What is ultrasonic Wet Milling and Micro-Grinding?   Ultrasonic wet grinding is a material processing method that combines ultrasonic technology with wet grinding process. It is mainly used for the refinement and dispersion of granular materials. The following is a detailed introduction to its principles, equipment, applications and advantages: Principle: In the wet grinding process, the material is usually mixed with an appropriate amount of liquid (such as water or other solvents) to form a slurry. Then, the ultrasonic generator is used to generate high-frequency vibration, and the electrical energy is converted into mechanical energy through the transducer, so that the ultrasonic energy is transmitted to the slurry. Under the action of ultrasonic waves, the liquid medium in the slurry will produce strong cavitation effect, mechanical vibration and stirring. The cavitation effect will form countless tiny bubbles in the liquid. When these bubbles collapse instantly, they will produce local high temperature, high pressure, strong shock waves and microjets, which can effectively impact and crush material particles and reduce their size. At the same time, mechanical vibration and stirring help to evenly disperse the material particles, prevent particle agglomeration, and further improve the grinding effect. Equipment: It mainly includes ultrasonic generators, transducers, grinding containers and other parts. The ultrasonic generator is used to generate high-frequency electrical signals to provide energy for the entire system; the transducer converts the electrical signal into mechanical vibration and transmits the ultrasonic wave to the grinding medium; the grinding container is the place to hold the material and the grinding medium, and is usually made of corrosion-resistant and wear-resistant materials to meet the grinding needs of different materials. Application Nanomaterial preparation: When preparing nano-scale metals, ceramics, semiconductors and other materials, ultrasonic wet grinding can grind the initial coarse particles into nano-scale particles, which helps to control the size and shape of the particles and improve the performance of the materials. Electronic material processing: For electronic materials such as electronic ceramics and magnetic materials, high-purity and fine-grained powders can be obtained by ultrasonic wet grinding, which is conducive to improving the performance and reliability of electronic components. Biomedicine: In drug research and development and production, ultrasonic wet grinding can be used to grind drug raw materials into fine powder, increase the specific surface area of ​​drugs, and improve the dissolution rate and bioavailability of drugs. In addition, it can also be used to prepare nano drug carriers, etc. Paint and ink industry: Grind solid particles such as pigments and fillers into fine particle sizes so that they can be evenly dispersed in paints and inks, improve the covering power and gloss of the coating and the printing performance of the ink. Advantages High efficiency and energy saving: Compared with traditional grinding methods, ultrasonic wet grinding can achieve a higher grinding fineness in a shorter time, improve production efficiency, and because its energy is concentrated on the material particles, the energy consumption is relatively low. Good particle refinement effect: The material particles can be ground to nanometer or submicron level, and the particle size distribution is relatively uniform, which can meet the strict requirements of high-end materials for particle fineness. Gentle grinding process: Ultrasonic wet grinding is carried out in a liquid medium, avoiding the high temperature and mechanical stress that may be generated during dry grinding, and has little effect on the crystal structure and chemical properties of the material. It is suitable for some materials that are more sensitive to grinding conditions. Green and environmental protection: The liquid medium used in the wet grinding process can usually be recycled, reducing dust pollution and waste generation, and meeting environmental protection requirements.

What is the Ultrasonic Battery slurry dispersion machine? Battery slurry is a key material used in battery manufacturing, usually composed of active materials, binders, conductive agents and solvents. The following is a detailed introduction to its composition and function: Active material: It is the main substance in the battery where electrochemical reactions occur, and determines key indicators such as battery capacity, energy density and charge and discharge performance. For example, in lithium-ion batteries, commonly used active materials include lithium cobalt oxide, lithium iron phosphate, ternary materials (such as nickel cobalt manganese oxide), etc. as positive electrode active materials, while negative electrode active materials are usually graphite, etc. Binder: Its function is to bind particles such as active materials and conductive agents together to form an electrode structure with certain strength and stability, and enable the electrode to be firmly attached to the current collector. Common binders include polyvinylidene fluoride (PVDF), sodium carboxymethyl cellulose (CMC), styrene butadiene rubber (SBR), etc. Conductive agent: In order to improve the conductivity of the electrode, a conductive agent needs to be added. It can form a conductive network between the active material particles, reduce the resistance of the electrode, and enable electrons to be quickly transmitted in the electrode, thereby improving the battery's charge and discharge efficiency and rate performance. Commonly used conductive agents include carbon black, graphene, carbon nanotubes, etc. Solvent: Mainly used to dissolve binders and disperse other components to give the slurry good fluidity and coating properties. In the preparation of battery slurry, the solvent can help the components to mix evenly and form a stable suspension. When the slurry is applied to the current collector, the solvent will evaporate, leaving solid electrode materials. Commonly used solvents in lithium-ion battery slurries include N-methylpyrrolidone (NMP), etc. The performance of battery slurry has a crucial impact on the overall performance and quality of the battery. Parameters such as slurry uniformity, viscosity, solid content, etc. need to be strictly controlled to ensure the consistency and stability of the electrode, thereby improving the performance, life and safety of the battery.   The ultrasonic machine is used to disperse positive and negative electrode materials, nano-electrode materials, and induce crystallization of lithium batteries. It improves the uniformity of slurry, shortens the time of traditional slurry stirring, improves slurry making efficiency, and reduces costs. After making the battery cell, the internal resistance of the product is reduced, the consistency is improved, the cycle life is long, and the capacity retention rate is high. It is more significant in the mixture with nano-level materials, effectively breaking up the agglomerates, and the storage time is long and stable.   Ultrasonic waves can be used to disperse battery slurry for the following reasons: Cavitation: When ultrasonic waves propagate in liquid, cavitation occurs. When the sound pressure of ultrasonic waves reaches a certain level, tiny bubbles in the liquid will expand rapidly in the negative pressure stage and then collapse sharply in the positive pressure stage. This instantaneous collapse of bubbles will produce local high temperature, high pressure, strong shock waves and microjets, which can effectively break up the agglomerates in the slurry, evenly disperse the particles in the liquid, prevent particle precipitation and agglomeration, and improve the stability of the slurry. Mechanical vibration: The high-frequency vibration of ultrasonic waves can subject the particles in the battery slurry to periodic mechanical forces. This mechanical force can overcome the interaction forces such as van der Waals force and electrostatic attraction between particles, and disperse the agglomerated particles. At the same time, vibration can also promote the mixing of the components in the slurry, so that additives are evenly distributed in the slurry, which is conducive to improving the consistency and performance of the slurry. Accelerate the mass transfer process: Ultrasonic waves can enhance the mass transfer process in liquids. In battery slurry, it can accelerate the interaction between solvent molecules and particle surfaces, promote the wetting and penetration of solvent into particles, and make particles more easily surrounded by dispersion medium, thereby improving the dispersion effect. In addition, the acceleration of mass transfer process is also conducive to chemical reactions. For example, in the slurry preparation process, if some additives are involved in dissolution or chemical reactions, ultrasound can make these processes more complete and uniform.  

What is the ultrasonic tinning machine?   Ultrasonic tinning is a tinning process assisted by ultrasonic technology. Tinning is a process of coating tin on the metal surface. It is often used in the pins, wire joints and other parts of electronic components to improve conductivity, solderability and corrosion resistance. The ultrasonic tinning machine applies ultrasonic waves to the tin liquid, which will produce high-frequency vibrations of more than 20,000 times per second and cause cavitation effects; once the metal workpieces that need to be tinned or soldered are immersed in the tin liquid, the oxide layer on the surface of the workpiece will be stripped off and removed, and the gap air will be precipitated, so that the tin liquid will be more evenly and firmly attached to the surface of the metal workpiece. In the traditional tinning process, flux is usually required to remove the oxides on the metal surface so that the tin can be well attached to the metal surface. Ultrasonic tinning introduces ultrasonic vibrations during the tinning process. When ultrasonic waves propagate in a liquid medium (such as tin liquid), cavitation effects, mechanical stirring effects and thermal effects will occur. The tiny bubbles generated by the cavitation effect will produce local high temperature and high pressure when they burst, which can effectively remove oxides and impurities on the metal surface, make the metal surface cleaner, and facilitate the wetting and adhesion of tin. Mechanical stirring helps to evenly distribute the tin liquid and improve the quality and uniformity of tin plating. The thermal effect can make the temperature of the tin liquid more uniform, promote the alloying reaction between tin and the metal surface, and thus improve the bonding strength of the tin plating layer. The tinning process does not require the use of flux, which improves the solderability and ductility of the metal; the workpiece parts that need to be tinned only need to be directly immersed in the tin bath for 3 to 10 seconds. It is commonly used for surface treatment and welding of metal parts in the electronics, electrical, automotive, new energy and other industries, such as tin plating or welding of silver, copper, nickel, aluminum and other wire harnesses, tabs, and sheets. Characteristics of ultrasonic tin plating: Improve the quality of tin plating: It can more thoroughly remove oxides and impurities on the metal surface, make the bond between the tin layer and the metal matrix closer, reduce defects such as cold soldering and leaking soldering, and improve the quality and reliability of the tin plating layer. Enhance solderability: The metal surface treated with ultrasonic tin plating has significantly improved solderability, which is beneficial to the subsequent welding process, can reduce the occurrence of poor welding, and improve the strength and conductivity of the welded joint. Environmental protection and energy saving: Compared with the traditional tinning process, ultrasonic tinning can reduce the use of flux and reduce the pollution of flux to the environment. At the same time, the energy consumption of ultrasound is relatively low, which has a certain energy-saving effect. Wide range of applications: It can be applied to the tinning treatment of various metal materials, including copper, aluminum, iron, etc., especially for some metal materials that are difficult to tin, ultrasonic tinning technology has better effects. Ultrasonic tinning equipment is mainly composed of the following parts: 1. Ultrasonic transducer vibration system: including ultrasonic generator, transducer, etc. The ultrasonic generator generates an ultrasonic electrical signal, and the transducer converts the electrical power into ultrasonic mechanical energy to form ultrasonic vibration, providing the required high-frequency vibration energy for the tinning process. 2. Tin tank with heating device: used to hold tin liquid, the heating device can keep the tin liquid at a suitable temperature, generally higher than the melting point of tin 20-30°C, to ensure the fluidity of the tin liquid, which is conducive to tinning. 3. Temperature control device: accurately control the temperature of the tin liquid in the tin tank to ensure temperature stability and avoid affecting the tinning quality due to excessively high or low temperature. 4. Transducer cooling device: Since the ultrasonic transducer generates heat when working, especially in a high-temperature tin-plating environment, the cooling device can cool the transducer to prevent it from overheating and ensure its performance and service life. 5. DC polarized power supply: Some ultrasonic tin-plating devices will have a DC polarized power supply, which can improve the propagation effect of ultrasonic waves in the tin liquid and the effect on the metal surface to a certain extent, which helps to improve the quality of tin-plating. In addition, some ultrasonic tin-plating equipment may also include control components such as foot switches to facilitate operators to control the operation of the equipment; and water tanks to provide a water circulation system for ultrasonic transducer cooling 5. For special-purpose ultrasonic tin-plating equipment, such as special equipment for ultrasonic tin-plating of aviation aluminum cables, two identical ultrasonic transducer vibration systems may be used, and the end face of the amplitude rod is an arc-shaped concave surface, so that the cable surface can be evenly tinned.

Do you know what is the Ultrasnic water spout vibration and fall？   Ultrasnic water spout vibration and fall is a device that uses ultrasonic technology to remove the sprue of plastic products. The process of separating the injection mold product from its runner by applying ultrasonic energy to the limited area of ​​the sprue (runner opening) of the injection mold product is called dewatering. When the ultrasonic energy activates the sprue with a very small cross-section, the high temperature activates the friction between the plastic molecules, and the stress here increases, causing the injection molded product and the runner to break at the sprue. The Ultrasnic water spout vibration and fall Equipment uses high-frequency vibrating ultrasonic energy to convert electrical energy into mechanical energy through a transducer, so that the tool head (commonly known as an ultrasonic welding head) generates high-frequency vibration. When the ultrasonic welding head contacts the sprue of the plastic product, this high-frequency vibration causes violent friction of the plastic molecules at the sprue, thereby rapidly heating up to the melting point of the plastic. Under the combined action of high temperature and pressure, the connecting part between the sprue and the product body is melted and separated, achieving the purpose of removing the sprue. Equipment composition Ultrasonic generator: Generates high-frequency electrical signals to provide energy source for the entire equipment. Its power and frequency can be adjusted according to different processing requirements. Transducer: Converts the high-frequency electrical signal generated by the ultrasonic generator into mechanical vibration. It is usually made of materials such as piezoelectric ceramics and has high energy conversion efficiency. Ultrasonic welding head: Also known as the tool head, it is the part that directly contacts the plastic product. Its shape and size are customized according to different product shapes and sprue positions. It can transmit the mechanical vibration generated by the transducer to the sprue part to achieve precise dewatering operation. Fixture: Used to fix the plastic product to be processed, ensure the stability of the product position during the dewatering process, and ensure processing accuracy and quality. The fixture is usually specially designed according to the shape and size of the product to achieve fast clamping and positioning.   Principle: Put the plastic workpiece taken out of the injection molding machine into the fixed model, start the switch button, press the start switch, and the ultrasonic welding head descends and presses the plastic workpiece for high-frequency vibration. When the sprue with a small cross-section is activated by ultrasonic energy, the friction between the plastic molecules is activated due to the high temperature. At this time, the stress increases, resulting in the fracture of the flow channel at the injection molded product and the sprue. The surface of the nozzle workpiece after cutting is flat and smooth, without whitening, and it is as beautiful as direct injection molding, which saves a lot of labor and improves production efficiency. There are two types of ultrasonic nozzle cutting machines, one is vertical, similar to the structure of the welding head moving up and down, and the other is horizontal, contact structure, which does not require too much pressure; the horizontal structure is convenient for cooperation with the manipulator of the injection molding machine to achieve automatic operation. Ultrasonic nozzle cutting is particularly suitable for hard thermoplastics such as polystyrene, nylon, acrylonitrile-butadiene-styrene copolymer, polycarbonate, acrylonitrile-butadiene-styrene copolymer, polymethyl methacrylate, etc. The cross-sectional consistency of soft thermoplastics after water removal is poor.   Advantages of ultrasonic nozzle cutting High precision: It can accurately remove the nozzle without damaging the body of the plastic product, ensuring the appearance quality and dimensional accuracy of the product. The traditional method of mechanical cutting or manual trimming of nozzles is prone to problems such as uneven cutting and large dimensional deviation, especially for some plastic products with complex shapes and high precision requirements, it is difficult to ensure the quality of nozzle removal.   High efficiency: The ultrasonic dewatering process is fast and can complete the dewatering of a large number of products in a short time, thus improving production efficiency. Traditional dewatering methods, such as manual trimming, are slow, and long hours of work can easily lead to worker fatigue, affecting production efficiency.   Environmental protection and energy saving: Compared with traditional dewatering methods such as mechanical cutting or chemical dissolution, ultrasonic dewatering equipment does not require the use of tools or chemical solvents, which reduces tool wear and chemical pollution, and also reduces energy consumption. High degree of automation: It can be combined with automated production lines to achieve a series of operations such as automatic loading, positioning, dewatering and unloading, reduce manual intervention, and improve production stability and consistency. Application areas: It is widely used in the plastic processing industry, such as the production of plastic products in the fields of automotive parts, electronic appliances, medical devices, and daily necessities. For example, plastic buckles for automotive interior parts, edge dewatering of electronic housings, and plastic accessories for medical devices can all be processed efficiently and accurately using ultrasonic dewatering equipment.   What are the application scenarios of ultrasonic dewatering equipment? Ultrasonic dewatering equipment has a wide range of application scenarios in plastic processing and related industries. The following are some of the main aspects: Automotive parts manufacturing Automotive interior parts such as dashboards, door panels, seats, etc. are usually composed of multiple plastic parts, which will have sprues left after injection molding.

Plastic parts around automobile engines, such as intake manifolds, radiator grilles, etc., have high requirements for dimensional accuracy and appearance quality. Ultrasonic dewatering equipment can efficiently remove sprues without damaging the parts, meeting the high-quality production requirements of automotive parts. Electronic and electrical industry Plastic shells of various electronic products, such as mobile phone shells, computer cases, TV shells, etc., need to remove sprues during the production process to achieve a good appearance. Ultrasonic dewatering equipment can achieve fine processing, ensure that the edges of the shell are neat and smooth, and improve the overall quality and market competitiveness of the product. Small plastic parts in electronic appliances, such as connectors, sockets, switches, etc., have extremely high requirements for dimensional accuracy and consistency. Ultrasonic dewatering equipment can accurately remove the water outlet, ensure the quality stability of these parts, and meet the high-precision requirements of the electronics industry for products. Medical device production Disposable medical devices such as medical plastic syringes, infusion sets, and blood bags have strict standards for product cleanliness and appearance quality. Ultrasonic dewatering equipment uses a non-contact processing method that does not produce debris and contaminants, and can effectively remove the water outlet to ensure the safety and hygiene of medical devices. Plastic accessories in medical devices, such as medical catheters, dentures, and medical device housings, also require high-precision dewatering processing. Ultrasonic dewatering equipment can be customized according to different product shapes and sizes to meet the strict requirements of the medical device industry for product quality. Daily necessities and toy manufacturing In the production of daily necessities, the removal of water outlets for products such as plastic cups, plastic buckets, and plastic hangers is an important link. Ultrasonic dewatering equipment can quickly and efficiently complete the dewatering work, improve production efficiency, and at the same time ensure the appearance quality of the product to meet consumers' needs for the beauty and practicality of daily necessities. In the toy manufacturing industry, the shells and parts of various plastic toys need to be dewatered after injection molding. Ultrasonic dewatering equipment can achieve fine processing, ensuring that the surface of the toy is smooth, free of burrs and water residue, and ensuring the safety and comfort of children.

What is the Normal Application of ultrasonic welder?   Ultrasonic welding is a process that converts 50/60 Hz current into 15, 20, 30 or 40 KHz electrical energy through an ultrasonic generator. The converted high-frequency electrical energy is converted into mechanical motion of the same frequency again through a transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude-changing horn devices. The welding head transmits the received vibration energy to the joint of the workpiece to be welded, where the vibration energy is converted into heat energy by friction to melt the plastic. Ultrasonic waves can not only be used to weld hard thermoplastics, but also to process fabrics and films. The main components of an ultrasonic welding system include an ultrasonic generator, a transducer/horn/welding head triplex, a mold and a frame. Working principle: When ultrasonic waves act on the contact surface of thermoplastic plastics, high-frequency vibrations of tens of thousands of times per second will be generated. This high-frequency vibration with a certain amplitude will transmit ultrasonic energy to the welding area through the upper weldment. Since the acoustic resistance of the welding area, i.e. the interface between the two welds, is large, local high temperature will be generated. Due to the poor thermal conductivity of plastics, it cannot be dissipated in time and gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, it will be fused into one. When the ultrasonic wave stops acting, the pressure is allowed to continue for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding, and the welding strength can be close to the strength of the raw materials. The quality of ultrasonic plastic welding depends on three factors: the amplitude of the transducer welding head, the applied pressure and the welding time. The welding time and welding head pressure can be adjusted, and the amplitude is determined by the transducer and the horn. There is an appropriate value for the interaction of these three quantities. When the energy exceeds the appropriate value, the amount of plastic melted is large and the weld is easy to deform; if the energy is small, it is not easy to weld firmly, and the applied pressure cannot be too large. This optimal pressure is the product of the side length of the welded part and the optimal pressure per 1mm of the edge.   Ultrasonic welding is an efficient and environmentally friendly welding technology that is widely used in many fields. Its advantages mainly include the following points: 1. Fast welding speed: Ultrasonic welding uses high-frequency vibration to make the molecules on the surface of the weldment rub against each other to generate heat, achieving rapid welding.

Little damage to materials: Ultrasonic welding is a non-contact welding method. During the welding process, there is no need to apply excessive pressure and heat to the weldment, avoiding the influence of high temperature and mechanical force on the performance of the weldment material, such as deformation and embrittlement, etc. It is particularly suitable for some heat-sensitive or easily deformed materials. 5. Environmental protection and energy saving: During the ultrasonic welding process, there is no need to add welding materials such as flux and welding rods, no harmful gases and smoke will be generated, and there is no pollution to the environment; at the same time, due to the fast welding speed and low energy consumption, it has a good energy-saving effect. 6.

Among them, ultrasonic plastic welding machines, as a key technology, are gradually changing the production methods of automotive parts. ​ Ultrasonic plastic welding machines use high-frequency vibration waves to transmit to the surface of plastic parts, so that high-speed friction and instantaneous temperature rise occur between the contact surfaces, thereby achieving efficient welding of plastics. This technology has extremely wide applications in the field of automobile manufacturing. From plastic parts of the car body to car interiors and exterior parts, ultrasonic welding technology can be seen. ​ In the manufacturing of automotive plastic parts, ultrasonic plastic welding machines play an irreplaceable role.

Can you make the automated ultrasonic spray coating system?   What is the ultrasonic spray coating? Ultrasonic spray technology, also known as ultrasonic atomization or ultrasonic atomization, is a technology used to accurately generate fine droplets or particles of liquid. It uses ultrasonic vibrations to break down liquids into very small and uniform droplets, and can be used in various industries such as coatings, pharmaceuticals, electronics, and materials science. The material to be sprayed is first in a liquid state, and the liquid can be a solution, sol, suspension, etc. The liquid coating is first atomized into fine particles by an ultrasonic atomizer, and then evenly coated on the surface of the substrate by a certain amount of carrier gas, thereby forming a coating or film. The biggest difference between ultrasonic spraying and traditional single-fluid or two-fluid spraying is that the atomizer or atomizer nozzle uses an ultrasonic atomizer, that is, an ultrasonic nozzle.   An automated ultrasonic spray coating system typically consists of the following components: Ultrasonic Nozzles: These are responsible for creating a fine mist of the coating material. Motion Control System: It can be used to move the nozzles or the substrate being coated in a precise pattern. Fluid Delivery System: To supply the coating material to the nozzles. Control Unit: This is where the programming comes in, to orchestrate the operation of all the above components.     How the syringe pump work for coating?   The automated ultrasonic spray coating machine combined with the generator, spray nozzle and the liquid supply system. We use the continuous liquid supply system with two tubes. It can continuous transmission liquid to the nozzle. The system has LCD display, you can operate very easy by the touch screen. You can set all the data on the touch screen. The syringe pump has high precision control.  The flow rate is from 0.01ml/min to 70ml/min. A continuous ultrasonic syringe pump for coating is a specialized piece of equipment that combines the functions of a continuous - flow syringe pump and ultrasonic technology to achieve high - quality coating applications. Here is a comprehensive introduction:   Syringe and Pump Mechanism: The syringe serves as the reservoir for the coating material. The pump mechanism, typically driven by a motor (such as a stepper or servo motor), moves the plunger of the syringe at a regulated speed. This enables a continuous and accurate flow of the coating liquid from the syringe to the target surface. Ultrasonic Transducer: Made of piezoelectric materials, the ultrasonic transducer converts electrical energy into high - frequency mechanical vibrations. These vibrations are transmitted to the coating liquid as it passes through the system. Control System: It allows users to set and adjust various parameters such as the flow rate of the syringe pump, ultrasonic power, frequency, and the duration of the coating process. The control system ensures precise and repeatable operation. Nozzle or Dispensing Head: This component is responsible for directing the atomized coating material onto the substrate. Different nozzle designs can be used to achieve various spray patterns, such as a narrow jet or a wide - angle fan.   Working Principle Continuous Liquid Delivery: The pump mechanism pushes the plunger of the syringe at a constant speed, providing a continuous stream of the coating material. The flow rate can be precisely controlled according to the specific requirements of the coating task, whether it's a thin film or a thicker layer. Ultrasonic Atomization: As the coating liquid flows through the area where the ultrasonic vibrations are present, the high - frequency vibrations break the liquid into tiny droplets. This atomization process results in a fine and uniform mist of the coating material. Enhanced Coating Properties: The ultrasonic energy not only atomizes the liquid but also has additional effects on the coating. It can reduce the surface tension of the coating material, improving its wetting ability on the substrate. This leads to better adhesion and a more uniform coating distribution.   Advantages Uniform Coating Thickness: The combination of continuous flow and ultrasonic atomization ensures that the coating is applied evenly across the substrate, resulting in a consistent coating thickness. This is crucial for applications where precise thickness control is required, such as in microelectronics and optical coatings. Reduced Coating Defects: The fine atomization helps to minimize the formation of defects like streaks, bubbles, or uneven patches in the coating. This leads to a higher - quality finish and better performance of the coated product. Improved Adhesion: The ultrasonic - induced reduction in surface tension and the mechanical agitation of the coating material enhance its adhesion to the substrate. This results in a more durable coating that is less likely to peel or delaminate. Versatility: It can handle a wide range of coating materials, including viscous polymers, solvents, and aqueous solutions. This makes it suitable for various industries and applications. Applications Electronics: Coating printed circuit boards (PCBs) to protect against moisture, dust, and electrical shorts. It can also be used for applying conductive or insulating coatings on semiconductor devices. Optics: Applying anti - reflective, hydrophobic, or other functional coatings on lenses, mirrors, and optical filters to improve their optical performance. Medical Devices: Coating catheters, stents, and other medical implants with biocompatible materials to enhance their biocompatibility and reduce the risk of thrombosis or infection. Automotive and Aerospace: Applying thin protective or decorative coatings on small - scale components, such as sensors or interior parts, to improve their durability and appearance.  

Do you know the application of ultrasonic Electrolytic hydrogen spraying coating?     Ultrasonic atomization spraying electrolytic hydrogen production is a technology that applies ultrasonic atomization spraying technology to the field of electrolytic hydrogen production to improve the efficiency and performance of electrolytic hydrogen production. Electrolytic hydrogen production generates hydrogen and oxygen by electrolyzing water. In the electrolytic cell, a pair of electrodes immersed in the electrolyte are separated by a diaphragm to prevent gas penetration. When a certain voltage of direct current is passed, water decomposes. Principle: Ultrasonic atomization spraying technology uses the energy of ultrasonic waves to convert high-frequency sound waves into mechanical energy through piezoelectric transducers, and then applies mechanical energy to liquids to generate standing waves in the liquid film at the top of the ultrasonic nozzle. These stationary liquid waves extend upward from the top of the ultrasonic nozzle. When the droplets leave the atomization surface of the nozzle, they are decomposed into a uniform fine mist of micron-level or even nano-level droplets, and then evenly coated on the surface of the substrate by a certain amount of carrier gas to form a coating or film. Advantages: It has the advantages of high coating uniformity, high raw material utilization, high coating thickness control accuracy, thinner coating thickness, less splashing, no nozzle clogging, and low maintenance cost. Application of ultrasonic spraying in electrolytic hydrogen production Electrode coating formation: The catalytic material required for electrolytic hydrogen production is evenly sprayed on the electrode surface. Through ultrasonic spraying, the coating particles can be better dispersed and more closely combined with the electrode surface, improving the adhesion and stability of the coating, effectively increasing the surface area and activity of the electrode, and thus improving the efficiency and hydrogen production rate of electrolytic hydrogen production. Electrode cleaning: During the electrolytic hydrogen production process, the electrode surface may be contaminated by oxides, impurities or sediments, reducing the electrolysis efficiency. The ultrasonic vibration generated by the ultrasonic spraying system can effectively remove pollutants on the electrode surface, improve the cleanliness of the electrode, and ensure the stability and continuity of the electrolytic hydrogen production process.   The significance of ultrasonic atomization spraying for electrolytic hydrogen production It can improve the protection effect and service life of the electrode, reduce the direct contact between the electrode and the electrolyte, and thus reduce the degree of corrosion and oxidation. At the same time, due to its characteristics such as precise control and high material utilization, it can reduce production costs and environmental impact, meet the needs of different electrolytic hydrogen production processes, ensure the quality and stability of the coating, and help promote the development and application of electrolytic hydrogen production technology. Among several major water electrolysis technologies, proton exchange membrane water electrolysis (PEM) is considered to be an ideal choice for coupling with renewable energy. Ultrasonic atomization spraying technology has broad application prospects in PEM electrolytic hydrogen production. For example, when preparing the electrode coating of the PEM electrolyzer, it can accurately control the catalyst loading and coating thickness, improve the performance and stability of the electrode, and thus improve the overall efficiency and economy of the PEM electrolytic hydrogen production system. Ultrasonic atomization spraying can improve the efficiency of electrolytic hydrogen production by optimizing electrode performance, promoting electrolyte diffusion and bubble discharge, as follows: Optimize electrode performance Improve catalyst loading uniformity: Ultrasonic atomization spraying can atomize the catalyst solution into tiny droplets and spray them evenly on the electrode surface. This allows the catalyst to be more evenly distributed on the electrode, the active sites to be fully utilized, and the actual reaction area of ​​the electrode to be effectively increased, so that the electrolysis reaction can proceed more fully, thereby improving the efficiency of hydrogen production. Enhance the bonding force between the coating and the electrode: During the spraying process, this technology uses the energy of ultrasound to better embed the catalyst particles into the electrode surface to form a strong bond. This not only improves the stability of the coating and reduces the shedding of the catalyst during the electrolysis process, but also reduces the contact resistance between the electrode and the coating, making the electron transmission smoother and accelerating the electrolysis reaction rate. Accurately control the coating thickness: Ultrasonic atomization spraying can accurately control the thickness of the catalyst coating. The appropriate coating thickness can ensure that the catalyst has enough active sites to participate in the reaction, and can also avoid the ion diffusion path being too long due to the excessive thickness of the coating, thereby improving the efficiency of the electrolysis reaction. Promote electrolyte diffusion Improve electrolyte distribution: In the electrolytic cell, ultrasonic atomization spraying can evenly distribute the electrolyte on the electrode surface and nearby areas. This helps maintain the uniformity of the electrolyte composition on the electrode surface, avoids the reduction of reaction rate caused by local concentration differences, makes the electrolysis reaction more uniform over the entire electrode surface, and improves the overall hydrogen production efficiency. Accelerate ion transmission: The vibration of ultrasound can promote the transmission of ions in the electrolyte. On the one hand, vibration accelerates the diffusion rate of ions in the electrolyte. On the other hand, it also helps to break the diffusion layer on the electrode surface, making it easier for ions to reach the electrode surface to participate in the reaction, thereby increasing the rate of electrolysis reaction and thus improving the efficiency of hydrogen production. Facilitates bubble discharge Reduce bubble size: The ultrasonic cavitation effect generated during ultrasonic atomization spraying can break the bubbles in the electrolyte into smaller bubbles. Small bubbles have less adhesion to the electrode surface and are more likely to detach from the electrode surface, thereby reducing the adhesion of bubbles to the electrode surface and increasing the effective reaction area of ​​the electrode. Promote bubble detachment: The vibration of ultrasound can destroy the adhesion stability of bubbles on the electrode surface, making it easier for bubbles to detach from the electrode surface under the action of buoyancy and liquid flow. Timely discharge of bubbles can prevent bubbles from gathering on the electrode surface, hindering the contact between the electrolyte and the electrode, thereby improving the efficiency of hydrogen production by electrolysis.

What is the ultrasonic degassing and defoaming machine?   Ultrasonic defoaming is a method that uses the physical effect of ultrasound to eliminate foam in liquids. Ultrasonic defoaming is mainly based on the cavitation effect and mechanical effect of ultrasound. When ultrasound propagates in liquid, it will generate a series of sparse and dense longitudinal waves, resulting in the formation of local high-pressure and low-pressure areas inside the liquid. In low-pressure areas, tiny bubbles in the liquid will expand rapidly, while in high-pressure areas, these bubbles will shrink sharply or even burst. This rapid expansion and rupture process of bubbles, namely the cavitation effect, will produce strong impact and shear forces, thereby destroying the liquid film of the foam and causing the foam to burst and disappear. At the same time, the mechanical effect of ultrasound will also cause violent vibrations in the liquid molecules, promote the flow and mixing of the liquid, accelerate the drainage process of the foam, and further promote the collapse of the foam. Ultrasonic degassing is a method of removing dissolved gases from liquids using ultrasonic technology. The vibration of ultrasound can accelerate the diffusion rate of gas molecules in liquids. On the one hand, ultrasound causes liquid molecules to vibrate violently, disrupting the distribution of gas molecules in the liquid and causing gas molecules to diffuse from areas of high concentration to areas of low concentration; on the other hand, vibration changes the microstructure of the liquid, reducing the diffusion resistance of gas molecules in the liquid, accelerating the migration speed of gas to the surface of the liquid, and facilitating the discharge of gas. The ultrasonic degassing device is mainly composed of an ultrasonic generator, a transducer, and a degassing container. The ultrasonic generator is used to generate high-frequency electrical signals, and the output power and frequency can generally be adjusted according to different application requirements. The transducer converts the electrical signal into ultrasonic mechanical vibration and transmits it to the liquid in the degassing container. The design of the degassing container needs to take into account the flow characteristics of the liquid and the propagation effect of ultrasound to ensure that the ultrasound can act evenly on the liquid and achieve efficient degassing. Some more complex devices may also be equipped with auxiliary equipment such as liquid circulation systems and temperature control systems to optimize the degassing process.   Ultrasonic equipment can effectively degas and defoam liquids. In this case, ultrasound removes small suspended bubbles from the liquid and reduces the level of dissolved gas to below the natural equilibrium level. 01 There are many uses for liquid defoaming and degassing: --Particle size measurement before sample preparation to avoid measurement errors; --Degassing of oil and lubricating oil before pumping to reduce pump wear due to cavitation; --Degassing of liquid foods (such as juice, soy sauce or alcoholic products) to reduce microbial growth and extend shelf life; --Defoaming of toiletries (hand soap, shampoo, laundry detergent, etc.);   When ultrasonically treating a liquid, the sound waves propagating from the radiating surface into the liquid medium create alternating cycles of high pressure (compression) and low pressure (rarefaction) at a rate that depends on the frequency. During the low pressure cycles, the high intensity of the ultrasound waves creates small vacuum bubbles or voids in the liquid. A large number of small bubbles are evenly distributed in the liquid, creating a large bubble surface area. Dissolved gases migrate into these vacuum (low pressure) bubbles through the larger surface area and increase the size of the bubbles. The sound waves support the contact and merging of neighboring bubbles, thus accelerating bubble growth. The sound waves will also help to detach bubbles from the container surface and force smaller bubbles located below the liquid surface to rise and release entrained gas into the environment. The degassing and defoaming process of a liquid is easy to see. In a glass beaker filled with fresh tap water, ultrasonic treatment will force small suspended bubbles to coalesce and move upward rapidly. You can see this effect in the progress image below The original liquid contains a large number of suspended bubbles. This is a problem especially in coolants, as the bubbles promote cavitation in pumps and nozzles, causing wear. The progress graph below shows the effect of ultrasonic defoaming. Ultrasonic treatment also produces bubbles in clear water after leaving the water to stand for 24 hours. The gas migrates into the bubbles, which fill with dissolved gas. As a result, the bubbles grow and move upward. The degassing effect is noticeable in any translucent liquid. Since ultrasound improves the rise of small suspended bubbles to the surface of the liquid, it also reduces the contact time between the bubbles and the liquid. Therefore, it also limits the redissolution of gas from the bubbles into the liquid. This is particularly interesting for high viscosity liquids, such as oils or resins. Since the bubbles have to move to the surface of the liquid, ultrasonic degassing is better if the container is shallow, so the time to the surface is shorter.

Have you ever used ultrasonic food cutter for cake cutting?   The principle of ultrasonic food cutting machine is to use the high-frequency vibration of ultrasound for cutting. Specifically, the ultrasonic driving power supply converts electrical energy into high-frequency and high-voltage alternating current, transmits it to the ultrasonic transducer, and the transducer converts electrical energy into mechanical energy (i.e. ultrasound).

Why need ultrasonic spray nozzle for carbon nanotube coating?   Ultrasonic carbon nanotube coating is a new type of coating that combines ultrasonic spraying technology and carbon nanotube material properties. The following is a related introduction: Composition and structure Carbon nanotubes are a nanoscale tubular material composed of carbon atoms, which has unique one-dimensional nanostructure, excellent mechanical properties, high conductivity and good chemical stability. In the coating, carbon nanotubes, as a key component, usually exist in a uniformly dispersed form, forming a network or interwoven microstructure, which provides basic performance support for the coating. Preparation method Ultrasound plays an important role in the coating preparation process. Generally, carbon nanotubes are mixed with appropriate solvents, binders, etc. to form a coating system, and then the high-frequency vibration generated by ultrasonic equipment is used to make the carbon nanotubes fully dispersed and uniform in the coating. The cavitation effect of ultrasound can break the agglomerates between carbon nanotubes, so that they are evenly distributed in the coating precursor in the form of single or small bundles. Subsequently, the coating is applied to the surface of the substrate by spraying, brushing, etc., and then the final coating is formed through processes such as drying and curing. Why choose ultrasonic  spray nozzle equipment?       Mainly because this equipment can efficiently atomize carbon nanotube suspension, spray evenly and accurately control the coating thickness. The following is a specific analysis: Efficient atomization: Ultrasonic atomization spray equipment uses high-frequency vibration of ultrasound to convert carbon nanotube suspension into tiny droplets. This atomization method can produce droplets with uniform particle size, and the droplet size can generally be controlled between a few microns and tens of microns. For carbon nanotube spraying, such a particle size can not only ensure that the carbon nanotubes are evenly distributed in the droplets, but also enable the droplets to better adhere to the substrate surface during the spraying process, avoiding the agglomeration or uneven distribution of carbon nanotubes due to excessive droplets. Uniform spraying: The tiny droplets produced by ultrasonic atomization can be more evenly distributed on the substrate surface during spraying. Compared with traditional spraying methods, such as pressure spraying or electrostatic spraying, ultrasonic atomization spraying equipment can reduce the splashing and uneven deposition of droplets. This is because the vibration of the ultrasonic wave makes the droplets have a more consistent speed and direction when leaving the nozzle, thus forming a more uniform coating on the surface of the substrate. For carbon nanotube coatings, uniformity is crucial, which can ensure that the performance of the coating remains consistent in different areas, such as no obvious differences in conductivity, mechanical properties, etc. Precise control: Ultrasonic atomization spraying equipment can accurately control the spraying amount and coating thickness of carbon nanotube suspension by adjusting the power, frequency, spraying time, speed and other parameters of the ultrasonic wave. In the application of carbon nanotube coatings, there are often strict requirements on the thickness of the coating. For example, in the electrode coating of electronic devices, the thickness of the carbon nanotube coating needs to be precisely controlled to achieve the best conductivity and electrical properties. This precise control capability of ultrasonic atomization spraying equipment helps to meet the strict requirements of carbon nanotube coating thickness in different application scenarios and improve the quality and consistency of the coating. Reduce agglomeration: Carbon nanotubes are prone to agglomeration due to their high specific surface area and surface activity. The cavitation effect and mechanical vibration during the ultrasonic atomization process can disperse the carbon nanotube agglomerates to a certain extent, so that the carbon nanotubes can maintain a good dispersion state in the suspension. In this way, during the spraying process, coating defects caused by carbon nanotube agglomeration, such as excessive local concentration and uneven coating, can be avoided, which is conducive to the formation of high-quality carbon nanotube coatings. Small impact on material properties: The ultrasonic atomization spraying process is relatively gentle, and during the atomization and spraying process, it will not cause significant damage or changes to the structure and properties of carbon nanotubes. Carbon nanotubes can maintain their original excellent properties, such as high strength and high conductivity, thereby ensuring that the carbon nanotube coating after spraying can give full play to its due performance advantages.

What is the different between ultrasonic batch/cleaner and ultrasonic probe machine for liuqid treatment?   Ultrasonic cleaning principle: mainly based on the physical effects such as cavitation effect, radiation pressure and mechanical vibration generated when ultrasonic waves propagate in liquids. Cavitation bubbles are generated, grown and collapsed in liquids, generating strong impact force, which can remove dirt, particle impurities and other impurities on the surface of objects. For example, when cleaning eyeglass lenses, ultrasonic cavitation can remove pollutants such as dust and grease attached to the surface of the lenses. ​ Ultrasonic sonochemical principle: In addition to the cavitation effect, it emphasizes the use of extreme physical and chemical environments (such as high temperature, high pressure, high-speed microjets, etc.) generated during the cavitation process to trigger chemical reactions. In solution processing, these conditions can significantly change the activity and reaction rate of molecules in the solution. For example, in organic synthesis reactions, ultrasonic waves can cause the chemical bonds of reactant molecules to break and recombine, thereby achieving chemical reactions that are difficult to carry out under normal conditions. ​   Poor extraction effect Lack of targeted parameter adjustment: The main design purpose of ultrasonic cleaning machines is to clean dirt on the surface of objects. For solution extraction work, its parameter adjustment is very limited. Taking the extraction of effective ingredients from Chinese medicinal materials as an example, professional extraction equipment can accurately control temperature, pressure, solvent flow rate, etc., and optimize extraction conditions according to the characteristics of medicinal materials. However, ultrasonic cleaning machines can only simply adjust the power and time. Unlike professional equipment, they cannot set appropriate extraction parameters according to the cell wall structure of different medicinal materials, the chemical properties of the active ingredients, etc., resulting in low extraction efficiency. Low extraction rate and long time: Compared with professional extraction devices such as Soxhlet extractors, the extraction rate of ultrasonic cleaning machines is obviously insufficient. Soxhlet extractors can continuously extract the extracts through repeated reflux of solvents, greatly improving the extraction efficiency. Ultrasonic cleaning machines use cavitation to extract. Although the cavitation effect can destroy the cell structure, it cannot achieve efficient recycling of solvents and extracts like professional equipment, which greatly prolongs the extraction time. At the same time, the extraction rate is difficult to reach the ideal level. It is not suitable for large-scale production or scenarios with high requirements for extraction volume. Limited dispersion capacity The processing volume is difficult to meet the demand: the amount of solution dispersion required in industrial production is often large, while the working tank volume of ultrasonic cleaning machines is generally small. In the production of coatings, a large amount of pigments need to be evenly dispersed in the solvent to form a stable coating solution. The amount of solution that an ultrasonic cleaning machine can process at one time is far from meeting the production scale. Frequent operation is not only inefficient, but also increases production costs and time costs. Poor treatment effect of special solutions: ultrasonic cleaning machines are unable to cope with high-concentration and high-viscosity solutions. In the production of inks, the ink solution has high viscosity characteristics. When ultrasonic waves propagate in such solutions, the energy decays rapidly, and cavitation bubbles are difficult to effectively generate and collapse, resulting in the inability to fully exert the cavitation effect, effectively break up particle agglomerates, and achieve uniform dispersion, which ultimately affects product quality. Different effects produced​ Ultrasonic cleaning effect: focuses on physical cleaning effects. Its main function is to clean the surface of objects, separate pollutants from the surface of objects and disperse them in the solution, but the chemical properties of the solution itself are slightly changed. For example, cleaning the oil stains on the surface of metal parts only peels off the oil stains from the surface of the parts into the cleaning solution, and the chemical composition of the cleaning solution remains basically unchanged. ​ Ultrasonic sonochemical effect: not only can physical dispersion be achieved, but also a series of chemical changes can be triggered. The high temperature (about 5000K) and high pressure (about 100MPa) environment generated at the moment of cavitation bubble collapse can promote the cracking of molecules in the solution, the generation of free radicals and other reactions. For example, in wastewater treatment, ultrasonic sonochemistry can produce strong oxidizing free radicals to oxidize and decompose difficult-to-degrade organic pollutants into harmless small molecules, thereby achieving a deep change in the chemical composition of the solution. ​ Different application scenarios​ .Ultrasonic cleaning application scenarios: Applicable to situations where dirt and impurities on the surface of objects need to be removed and the cleanliness of the surface of objects needs to be restored. It is commonly used in the fields of electronic component cleaning and pretreatment before medical device disinfection. It mainly focuses on the surface cleaning of objects and does not require high depth of solution treatment. ​ Ultrasonic sonochemistry application scenarios: Widely used in scenarios where solutions need to be chemically modified and chemical reactions need to be promoted. In material synthesis, it can be used to prepare nanomaterials, and the particle size and structure of the materials can be precisely controlled through chemical reactions triggered by ultrasound; in the field of environmental remediation, it is used to treat contaminated water bodies and deeply purify solutions.

Ultrasonic blood collection tube spray coating system    Ultrasonic blood collection tube atomization spraying: opening a new chapter in precision medicine in modern medical diagnosis, blood collection tubes are key tools for obtaining human blood samples. With the continuous advancement of medical technology, the performance requirements for blood collection tubes are becoming increasingly stringent. Ultrasonic blood collection tube atomization spraying technology came into being. With its unique advantages, it has brought revolutionary changes to the production and manufacturing of blood collection tubes, and has strongly promoted the development of precision medicine.   The core of ultrasonic blood collection tube atomization spraying technology is to use the high-frequency vibration of ultrasound. Through the ultrasonic generator, the signal is transmitted to the transducer, which converts electrical energy into mechanical energy, thereby triggering high-frequency vibration of the nozzle. When the spray liquid flows through the nozzle, it is efficiently dispersed into extremely small droplets under the action of high-frequency vibration. These tiny droplets are sprayed on the inner wall of the blood collection tube in a uniform and fine state, forming a thin and uniform coating. Compared with traditional spraying technology, ultrasonic atomization spraying can make the coating thickness more accurately controllable, usually accurate to the micron level, which is a precision that traditional technology cannot achieve.   Ultrasonic blood collection tube spray systems are specifically designed for applying blood collection tube coatings such as clot activators and anticoagulants. Ultrasonic technology provides excellent coating uniformity and repeatability. An example of a common ultrasonic spray application for blood collection tubes is spraying silica coatings to accelerate clotting. A silica slurry is sprayed onto the tube wall to form a uniform film of silica particles. Ultrasonic spray is beneficial in this specific application because the ultrasonic vibrations of the spray head break up any silica agglomerates, ensuring uniform coating on the tube wall. In addition, spray heads of different lengths can be configured, depending on the diameter and length of the tube.   The ultrasonic spray system evenly applies clot activators and anticoagulants including heparin, EDTA, silica, and acid citrate dextrose. Designed for easy integration into high-volume OEM production lines. Ultrasonic spray technology provides excellent coating uniformity and repeatability, and the precise fine-tuning function produces tighter droplet distribution and smaller droplets for consistent and fast-drying dispersions.   2. Significant advantages 1. Excellent coating uniformity: Traditional spraying methods are prone to uneven coating thickness, which may cause abnormal blood coagulation or uneven distribution of additives in blood collection tubes when storing blood samples. Ultrasonic atomization spraying technology, with uniform tiny droplets generated by high-frequency vibration, ensures that the coating is evenly covered on the inner wall of the blood collection tube. Whether it is a straight tube section or a curved part, the coating thickness deviation is extremely small, ensuring the stability and consistency of the blood sample in the tube. 1. Saving raw materials: Ultrasonic atomization spraying can accurately control the coating thickness, avoiding material waste caused by excessive spraying. Traditional spraying methods often require repeated spraying to achieve a uniform effect, consuming a lot of raw materials. Ultrasonic technology only needs one precise spraying to meet the coating requirements, greatly reducing production costs. According to statistics, in large-scale production, the use of ultrasonic atomization spraying can save about 30% - 40% of raw materials. 1. Improve production efficiency: This technology has a fast spraying speed and a good one-time molding effect. On a continuous production line, blood collection tubes can quickly pass through the spraying area to complete high-quality coating operations. Compared with the traditional cumbersome processes of multiple spraying and drying, ultrasonic atomization spraying greatly shortens the production cycle. For example, after introducing this technology, the daily output of a large blood collection tube production company increased by more than 50%.

Why need ultrasonic cutter for jumbo bag cutting?   Ultrasonic jumbo bag sealing and cutting is an advanced technology used in the processing and packaging of ton bags. The following is a related introduction: Ultrasonic ton bag sealing and cutting uses the high-frequency vibration energy of ultrasound to convert electrical energy into mechanical energy through a transducer to generate high-frequency vibration. The vibration is transmitted to the sealing and cutting tool or mold through the amplitude rod, so that the local area in contact with the ton bag material quickly generates heat. Under the combined action of heat and a certain pressure, the material of the ton bag (such as synthetic fibers such as PP and PET) melts rapidly, and the edges are fused and sealed while cutting, thereby preventing material leakage and ton bag edge wear.

Good incision quality: The cutting edge is neat and smooth, without burrs or slag, which will not damage the ton bag material, nor affect the overall strength and appearance of the ton bag. Strong adaptability: It can adapt to ton bags of various materials, such as synthetic fiber materials such as polypropylene and polyester, as well as ton bags made of some composite materials. High degree of automation: It can be used in conjunction with other automated packaging equipment to realize the fully automated production process of ton bag packaging, reduce manual operations, and improve the stability and consistency of production. Application scenarios Chemical industry: It is used to package various chemical raw materials, powders, granules, etc., such as plastic raw materials, fertilizers, pigments, etc., to ensure the safety and stability of chemical products during transportation and storage. Food industry: It can be used for ton bag packaging of bulk foods such as grain, feed, and sugar to ensure the hygiene and quality of food and prevent moisture and contamination. Building materials industry: For ton bag packaging of building materials such as cement, sand, and gravel, ultrasonic sealing and cutting can provide a firm seal and good sealing, which is convenient for transportation and use. Mineral industry: It is widely used in the packaging of mineral resources such as ore powder and metal particles, which helps to achieve efficient and safe material transportation and storage.   Compared with traditional sealing and cutting technology, ultrasonic sealing and cutting technology has many significant advantages in processing quality, production efficiency, environmental protection and energy saving, as follows: Processing quality The incision is smoother: Ultrasonic sealing and cutting uses high-frequency vibration to melt and cut the material locally, and the incision has almost no burrs or burrs, and the edges are very regular, while traditional hot knife cutting or mechanical cutting is prone to uneven incisions and jagged edges. Better sealing: Ultrasonic sealing and cutting can achieve good heat sealing effects while cutting, so that the sealing of the ton bag is tightly sealed and effectively prevents material leakage. In contrast, traditional sealing and cutting technology may require additional sealing processes, and the firmness and sealing of the sealing may not be as good as ultrasonic sealing and cutting. Little material damage: Ultrasonic waves act on the material for a short time and concentrate energy, and the heat-affected area of ​​the ton bag material is small, which is not easy to cause deformation, embrittlement and other problems of the material, and can maintain the original performance of the ton bag material to the greatest extent. Traditional high-temperature heat sealing and cutting technology may cause the material to be overheated, resulting in a decrease in material performance, while mechanical cutting may cause stress concentration near the incision, affecting the overall strength of the ton bag. Fast cutting speed: Ultrasonic sealing and cutting has a high working frequency and can quickly complete cutting and sealing operations. Its cutting speed is usually much faster than traditional mechanical cutting, which can effectively improve the production efficiency of ton bags and meet the needs of large-scale production. No need for preheating and cooling: Unlike some traditional heat sealing and cutting technologies, ultrasonic sealing and cutting does not require a long preheating process to reach the appropriate cutting temperature, nor does it require additional cooling time to solidify the seal, saving a lot of production time. High degree of automation: Ultrasonic sealing and cutting equipment is easier to integrate with automated production lines to achieve automated feeding, cutting, sealing and other operations, reducing manual intervention and improving the continuity and stability of production, while traditional sealing and cutting technology may have certain limitations in automated integration.

Which industries are ultrasonic defoaming used in?   Ultrasonic defoaming has been widely used in many industrial production fields due to its high efficiency and environmental protection. The details are as follows: 1. **Food processing industry**: During the production process of juice, beer, beverages, etc., a large amount of foam is easily generated. For example, in the juice concentration process, ultrasonic defoaming can effectively eliminate foam caused by material characteristics and process operations, ensuring the smooth progress of the concentration process and avoiding material loss and equipment contamination caused by foam overflow. In beer brewing, a large amount of foam will be produced during the fermentation stage. Ultrasonic defoaming can control the amount of foam and ensure the normal fermentation process without affecting the quality and taste of the beer.   2. **Chemical Industry**: In the production of chemical products such as coatings, adhesives, and inks, foam often occurs due to stirring, adding surfactants, etc. The use of ultrasonic defoaming can improve the quality and stability of products and avoid problems such as product surface defects and performance degradation caused by the presence of foam. For example, in paint production, foam will affect the leveling and glossiness of the paint. Ultrasonic defoaming can make paint production smoother and product quality more guaranteed.   3. **Biopharmaceutical industry**: During the biological fermentation process, the metabolic activity of microorganisms will produce a large amount of foam. Excessive foam will not only occupy space in the fermentation tank and affect fermentation efficiency, but may also increase the risk of bacterial contamination. Ultrasonic defoaming can effectively eliminate foam and maintain the stability of the fermentation process without affecting the growth and metabolism of microorganisms. In addition, in the production of pharmaceutical preparations, such as injections, oral liquids, etc., ultrasonic defoaming can also be used to remove foam generated during the production process to ensure product quality and safety.   4. **Sewage treatment industry**: In the sewage treatment process, the activated sludge method is a commonly used treatment method. However, a large amount of foam will be generated during the aeration process. These foams not only affect the treatment effect, but may also cause pollution to the surrounding environment. Ultrasonic defoaming can eliminate foam promptly and effectively, improve the operating efficiency of the sewage treatment system, and reduce the impact of foam on the environment.   5. **Papermaking Industry**: During the papermaking process, pulping, papermaking and other processes will produce foam. For example, in the pulping process, due to the addition of various chemicals, a large amount of foam is easily generated, which affects the quality of the slurry and the subsequent papermaking process. Ultrasonic defoaming can quickly eliminate foam, ensure the continuity of the papermaking process and the quality of the paper, and reduce paper holes, paper breaks and other defects caused by foam problems.   6. **Petroleum Extraction and Processing Industry**: During the oil extraction process, especially during the dehydration and degassing of crude oil, a large amount of foam will be generated. Ultrasonic defoaming can help improve the separation efficiency of crude oil, reduce the water and gas content in crude oil, and improve the quality of crude oil. In the petroleum refining process, foam generated in processes such as distillation and cracking can also be eliminated through ultrasonic defoaming technology to ensure the safety and stability of the production process.    

What is the ultrasonic defoaming?   Foam is a structure formed by gas wrapped in liquid, and is commonly found in products such as detergents, shampoos, and toothpastes. While foam can provide a good user experience in some products, it can be an undesirable factor in certain industrial processes. For example, in the food, pharmaceutical, chemical and other industries, foam can affect process control, product quality and production efficiency. Therefore, the research and application of foam elimination technology are of great significance. Principle of ultrasonic defoaming Ultrasonic defoaming is a physical phenomenon that uses ultrasonic vibration to act on foam. Ultrasound refers to sound waves with a frequency exceeding 20kHz. The principle of ultrasonic defoaming is to use the high-frequency vibration of ultrasonic waves to destroy the foam structure through the mechanical action of the foam liquid, causing the bubbles to collapse rapidly, thereby achieving the effect of eliminating foam. The specific principle is as follows 1. When ultrasonic vibration acts on foam liquid, a large number of tiny bubbles will be generated. These bubbles will rapidly expand and collapse under the action of ultrasonic vibration. 2. The shear force and pressure changes caused by ultrasonic vibration on the liquid reduce the interfacial tension between the gas and the liquid, which is conducive to bubble collapse. 3. The stirring effect of ultrasonic vibration on the liquid can bring the bubbles into better contact with the surrounding liquid, thereby accelerating the collapse of the bubbles.   Ultrasonic defoaming is a method that uses the characteristics of ultrasonic waves to eliminate foam. Its principles mainly involve the following aspects: 1. **Destroy the surface tension of foam**: Foam is formed by a liquid film wrapping a gas. There is surface tension between the molecules on the liquid surface, which keeps the foam in a relatively stable form. Ultrasound is a high-frequency mechanical wave. When ultrasonic waves act on the foam system, high-frequency vibrations will be generated. This vibration will produce strong disturbances in the liquid film of the foam, making the local surface tension distribution of the liquid film uneven. In the case of uneven surface tension, the stability of the foam is destroyed and the film is prone to rupture, resulting in the elimination of the foam.   2. **Cavitation**: When ultrasonic waves propagate in liquids, cavitation will occur. During the negative pressure half cycle of ultrasonic waves, tiny cavitation bubbles will form in the liquid. As these cavitation bubbles form and grow, they absorb gas and energy from the surrounding liquid. When the ultrasonic wave enters the positive pressure half cycle, the cavitation bubbles will quickly collapse and close. When the cavitation bubble collapses, it will produce extremely high pressure and temperature, as well as strong shock waves and micro jets. These energies and forces act on the foam, which can effectively destroy the structure of the foam and cause the foam to burst and disappear.   3. **Accelerate foam drainage**: The vibration effect of ultrasonic waves can accelerate the flow of liquid in the foam system and promote the liquid drainage process between foams. Under normal circumstances, the liquid between the bubbles will slowly drain out under the action of gravity and surface tension, causing the bubbles to gradually collapse. The effect of ultrasonic waves can speed up the discharge of liquid, causing the foam to lose liquid support faster, thereby accelerating the collapse of the foam.   4. **Inhibit foam generation**: In addition to eliminating existing foam, ultrasonic waves can also inhibit the formation of foam to a certain extent. Because the action of ultrasonic waves makes it difficult for the gas in the liquid to gather to form stable bubble nuclei, thereby reducing the possibility of new foam generation. This is because the high-frequency vibration and cavitation of ultrasonic waves will make the gas in the liquid disperse more evenly, making it difficult to form large bubbles that are large enough to develop into foam.  

What is the advantage of ultrasonic soldering iron?   Advantages of ultrasonic soldering iron compared to ordinary soldering iron Compared with ordinary electric soldering irons, ultrasonic soldering irons have a wider range of welding materials: ordinary electric soldering irons are mainly suitable for welding common metal materials, such as copper, iron, tin, etc. In addition to welding metal materials, ultrasonic soldering irons can also directly weld glass, ceramics, titanium alloys, stainless steel, molybdenum alloys and other materials that are difficult to weld with ordinary soldering irons. There is no need to pre-metalize these materials and other complex treatments, simplifying the process. , reducing costs.   Compared with ordinary electric soldering irons, ultrasonic soldering irons have the following advantages: Wider welding materials: Ordinary electric soldering irons are mainly suitable for welding common metal materials, such as copper, iron, tin, etc. In addition to welding metal materials, ultrasonic soldering irons can also directly weld glass, ceramics, titanium alloys, stainless steel, molybdenum alloys and other materials that are difficult to weld with ordinary soldering irons. There is no need to pre-metalize these materials and other complex treatments, simplifying the process. , reducing costs.   No flux required: Ordinary soldering irons usually require the use of flux to clean the welding surface and remove oxides during welding to ensure welding quality. Flux will produce harmful smoke during use, which is harmful to the human body and the environment, and additional cleaning is required after welding. The ultrasonic soldering iron uses the cavitation effect of ultrasonic waves to eliminate the need to use flux during the welding process, does not produce harmful smoke, avoids environmental pollution, reduces harm to the human body, and also eliminates the need to clean flux residue. , improve work efficiency.   Higher welding quality: Reduce false soldering: During the welding process of ordinary electric soldering irons, if the surface of the welded piece is improperly treated or heated unevenly, false soldering is likely to occur, resulting in poor contact at the soldering point and affecting the normal operation of the circuit. The ultrasonic soldering iron causes the solder to generate high-frequency friction on the welding surface through ultrasonic vibration, which can effectively remove oxides and impurities on the surface of the weldment, allowing the solder to better wet the surface of the weldment, thereby reducing the occurrence of false welding and false welding, and improving Welding reliability and stability.   Strong solder joints: The solder joints formed by the ultrasonic soldering iron are stronger and have high welding strength. The welding principle is to use ultrasonic vibration to cause the atoms on the surface of the solder and the weldment to diffuse and fuse with each other to form a metallurgical bond, rather than relying on the physical adhesion of the solder. Therefore, the solder joints after welding can withstand greater external force and vibration, and are less prone to problems such as falling off and loosening. They are suitable for occasions that require high welding quality, such as aerospace, automotive electronics and other fields.   Beautiful solder joints: The surface of the solder joints after welding with ordinary electric soldering irons may have defects such as unevenness and pores, which will affect the appearance quality of the product. The surface of the solder joints welded by the ultrasonic soldering iron is smooth, flat, without pores and defects, and the solder joints in the soldering area are more uniform and beautiful, which improves the overall quality and aesthetics of the product.   Higher welding efficiency: The welding speed of ultrasonic soldering iron is faster than that of ordinary soldering iron. On the one hand, there is no need to use flux and complex surface treatment, saving preparation time; on the other hand, its unique welding principle allows the solder to quickly wet and adhere to the surface of the weldment, reducing welding time. For example, in the mass production of electronic products, the use of ultrasonic soldering irons can significantly improve production efficiency and reduce production costs.    

What is the difference between ultrasonic lace machine and Ultrasonic radial sewing machine?     What is the ultrasonic lace machine? High-frequency oscillation is used to transmit sound waves from the welding head to the welding surface of the workpiece, which instantly causes friction between the molecules of the workpiece and reaches the melting point of the plastic, thereby completing the rapid dissolution and welding of solid materials. The traditional stitching step is abandoned and replaced by ultrasonic welding, making the operation simpler.     What is the Ultrasonic radial sewing machine? Its core technology lies in the use of a disc-shaped welding head for seam welding, which cleverly converts the longitudinal vibration of the transducer into the radial vibration of the disc-shaped welding head that radiates 360° outward in the diameter direction. The rotation of the welding roller and the pressure roller is completely synchronized, there is no difference in speed and angle, it will not cause the fabric to stretch or deform, and the accuracy is extremely high.    The bottom of the ultrasonic lace machine is an ultrasonic vibration plane, and the upper part is a steel sealing and cutting wheel. The wheel is often printed with patterns to make the welding surface beautiful. The cloth passes between the two, and through the ultrasonic vibration plane, the upper steel sealing and cutting wheel only needs to exert a small amount of pressure on the cloth to cut and weld the thermoplastic material. The vibration part of the ultrasonic sewing machine core is a circular vibrating disk. The cloth passes between the upper and lower disks, and both disks rotate at a certain speed. This can avoid wrinkles and out-of-synchronization problems caused by welding caused by one rotation of the lace machine.   The core technology of the ultrasonic seamless stitching system is the use of a disc-shaped welding head for seam welding, which cleverly converts the longitudinal vibration of the transducer into radial vibrations that the disc-shaped welding head radiates 360° outward in the diameter direction. And it is different from traditional lace machines, which generally consist of a flat tool head and a patterned roller. Since the tool head is stationary, it can easily cause fabrics such as fabrics to deform and wrinkle when working, and seam welding The seamless sewing equipment uses two discs to vibrate to sew fabrics, which solves this problem very well. This not only greatly reduces the size of the vibration system itself, but also greatly reduces the installation size. The whole machine is beautiful, the volume is reduced, and the weight is also greatly reduced.   Advantages of sewing machine core ◆High stability: During ultrasonic seamless sewing, the rotations of the welding roller and the pressure roller are completely synchronized, there is no difference in speed and angle, and the fabric will not be stretched or deformed, and the accuracy is extremely high. Due to the hot-melt effect, no needles and threads are needed, the product is more water-resistant, lighter in weight, and easier to fold.   ◆Welding and cutting synchronization: Ultrasonic seamless sewing equipment is not only suitable for continuous sewing, but also can cut textiles while welding to achieve automatic edge sealing.   ◆No heat radiation: During ultrasonic sewing, the energy penetrates the material layer for welding, and there is no heat radiation. During the continuous sewing process, heat will not be transferred to the product, which is especially beneficial for the packaging of heat-sensitive products.   ◆Controllable welding: the welding roller and pressure roller pull the fabric, and ultrasonic welding the fabric. Replacing the pressure roller can change the size and embossing of the weld, making it more flexible and convenient to use.   ◆Wide range of uses: All thermoplastic (softened after heating) fabrics, special tapes, and films can be welded using ultrasonic seamless sewing equipment. The rollers are made of quenched steel to extend their service life.

Cooling Systems: Often, a cooling system is used to maintain optimal temperatures during processing, especially for heat-sensitive components. 5. Pressure Application: In some setups, pressure can be applied to enhance cavitation effects. Considerations: The pressure conditions need to be optimized based on the specific slurry components. 6. Solvent Composition Influence: The choice of solvent (water, organic solvents, etc.) and its concentration can impact the dispersion quality. Viscosity: The viscosity of the solvent affects the efficiency of ultrasonic dispersion. 7. Particle Size Distribution Target Range: Monitoring the particle size before and after dispersion is crucial. Measurement: Techniques like laser diffraction or dynamic light scattering can be used to assess particle size distribution. 8. Additive Concentrations Conductive Additives: The concentration of conductive additives (e.g., carbon black, graphene) can be adjusted to optimize conductivity without compromising dispersion quality. Binders: The type and amount of binders also play a significant role in the slurry's final properties. 9. Batch Size Consideration: The volume of slurry being processed can affect the efficiency of ultrasonic dispersion. Scaling: Larger batch sizes may require different settings compared to small-scale experiments. Conclusion Optimizing these parameters is crucial for achieving the desired dispersion characteristics in electric slurries. By carefully adjusting frequency, amplitude, processing time, and other factors, manufacturers can enhance the performance and reliability of electric slurries in various applications, particularly in battery production.

What is the difference between ultrasonic cutting and laser cutting?   Now in the cutting industry, laser cutting and ultrasonic cutting are relatively high-end and high-tech cutting methods. Just like laser cutting and waterjet cutting, there are big differences in principles, costs, cutting methods and applications. So today we will talk about the difference between laser and ultrasonic cutting. The principles are different (1) Laser cutting principle The principle of laser cutting: Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby Achieve cutting the workpiece. Laser cutting is one of the thermal cutting methods. (2) Principle of ultrasonic cutting When ultrasonic technology is used for cutting, the back-and-forth vibration generated by the ultrasonic vibrator installed behind the spindle is transmitted to the outer circumferential part of the grinding wheel blade through the spindle and the base of the grinding wheel blade, and is converted into expansion motion in the radial direction. Through this vibration conversion method, the ideal vibration direction required for ultrasonic processing can be obtained. The mechanical vibration energy generated by the ultrasonic generator exceeds 20,000 blade vibrations per second, which locally heats and melts the material being cut, causing the molecular chains to quickly break apart to achieve the purpose of cutting the material. Therefore, ultrasonic cutting does not require a particularly sharp blade or a lot of pressure, and will not cause chipping or damage to the material being cut. At the same time, due to the ultrasonic vibration of the cutting blade, the friction is small, by reducing the material is not easy to stick to the blade. Especially effective for sticky and elastic materials that freeze, such as food, rubber, etc., or where it is inconvenient to add pressure to reduce objects. Different characteristics (1) Laser cutting characteristics As a new processing method, laser processing has gradually been widely used in the leather, textile and clothing industries due to its advantages of accurate processing, fast processing, simple operation, and high degree of automation. Compared with traditional cutting methods, laser cutting machines are not only lower in price and consumption. And because laser processing puts no mechanical pressure on the workpiece, the effect, accuracy and cutting speed of the cut products are very good. It also has the advantages of safe operation and maintenance Simple and other features. Can work continuously for 24 hours. The edges of the dust-free non-woven fabrics cut by the laser machine will not turn yellow, and will automatically close up without loose edges. They will not deform or harden, and will have consistent and precise dimensions. They can cut any complex shape; they are highly efficient and cost-effective. Computer designed graphics can cut lace of any shape and size. Fast development speed: Due to the combination of laser and computer technology, users can realize laser engraving output as long as they design on the computer and can change the engraving at any time. They can design and produce products at the same time. (2) Characteristics of ultrasonic cutting Ultrasonic cutting has the advantages of smooth and reliable incision, accurate edge cutting, no deformation, no edge warping, fluffing, stringing, and wrinkles. The avoidable "laser cutting machine" has shortcomings such as rough cutting edges, burnt edges, and pilling. However, the automation of ultrasonic cutting machines is currently more difficult than that of laser cutting machines, so the efficiency of laser cutting is currently higher than that of ultrasonic cutting. Different applications Laser cutting application areas Machine tools, engineering machinery, electrical switch manufacturing, elevator manufacturing, grain machinery, textile machinery, motorcycle manufacturing, agricultural and forestry machinery, food machinery, special automobiles, petroleum machinery manufacturing, environmental protection equipment, household appliance manufacturing, large motor silicon steel sheets and other machinery manufacturing processing industry. Ultrasonic application fields Another great advantage of ultrasonic cutting is that it has a fusion effect at the cutting site while cutting. The cutting area is perfectly edge-sealed to prevent the tissue of the cut material from loosening (such as flashing of textile materials). The uses of ultrasonic cutting machines can also be expanded, such as digging holes, shoveling, scraping paint, engraving, slitting, etc. 1. Plastic and thermoplastic door cutting and die cutting. 2.

When these bubbles collapse, they create intense local forces that help break apart the graphene clusters, leading to a more even dispersion in the liquid. This method is commonly employed to enhance the stability and homogeneity of graphene dispersions, making it easier to incorporate graphene into various materials, such as composites, coatings, or inks. The resulting dispersion can be utilized in applications ranging from electronics and energy storage to biomedical devices and sensors. The ultrasonic graphene dispersion process contributes to improving the performance and functionality of materials incorporating graphene.   Why should use ultrasonic machine to dispersion the graphene？ What is the advantage? Using an ultrasonic machine for graphene dispersion offers several advantages: Improved Dispersion Quality: Ultrasonic waves provide effective and uniform dispersion of graphene particles. This results in a more homogeneous distribution of graphene throughout the liquid medium, reducing agglomeration and ensuring better overall quality. Reduced Agglomeration: Graphene tends to form agglomerates or clusters, which can impact its properties and functionality. Ultrasonic dispersion breaks down these agglomerates into smaller particles, leading to improved stability and preventing the formation of large clusters. Increased Surface Area: Ultrasonic dispersion increases the surface area of graphene sheets. This is beneficial for applications where a higher surface area is desired, such as in energy storage devices or catalysts, as it enhances the material's performance. Enhanced Material Properties: The uniform dispersion achieved through ultrasonication can lead to improved mechanical, electrical, and thermal properties of materials containing graphene. This is crucial for applications like composites, coatings, and inks. Process Efficiency: Ultrasonic dispersion is a relatively fast and efficient process. It allows for the production of well-dispersed graphene in a shorter amount of time compared to other dispersion methods, making it a practical choice for large-scale manufacturing. Versatility: Ultrasonic dispersion is applicable to various liquid media and solvents, providing flexibility in terms of the types of solutions and materials that can be used in the dispersion process. Scalability: The ultrasonic dispersion process is scalable, making it suitable for both laboratory-scale research and industrial-scale production. This scalability is important for transitioning from research and development to large-scale manufacturing. Overall, the advantages of using an ultrasonic machine for graphene dispersion contribute to the improvement of graphene-based materials' performance and facilitate their integration into a wide range of applications. Do you have the graphene dispersion customer? Yes, of course. We already sold this machines to different customers. Not only for lab test, but also for industrial use. For circulation processor.Here is the feedback of our customer:   How is the ultrasonic machine to improve Dispersion quality? Ultrasonic machines improve the dispersion quality of graphene through a process called ultrasonication. Here's how the ultrasonic machine achieves this: Cavitation Effect: Ultrasonic waves create high-frequency pressure waves in the liquid medium. These waves lead to the formation of microscopic bubbles in the liquid, a phenomenon known as cavitation. Bubble Collapse: The cavitation bubbles generated during ultrasonication undergo rapid expansion and collapse. When these bubbles collapse, they create localized high temperatures and pressures. Shear Forces: The collapse of cavitation bubbles near graphene agglomerates generates intense shear forces. These forces act on the graphene particles, breaking down agglomerates into smaller particles. Homogeneous Dispersion: The shear forces and pressure variations induced by ultrasonication result in the separation and dispersion of graphene sheets in the liquid. This process breaks up large clusters and ensures a more uniform distribution of graphene throughout the medium. Preventing Re-agglomeration: As the dispersed graphene particles are subjected to the ultrasonic waves, the process helps prevent the re-agglomeration of particles. Continuous ultrasonication maintains a stable dispersion by inhibiting the formation of large clusters. Increased Surface Area: The mechanical action during ultrasonication increases the surface area of graphene sheets. This increased surface area can be beneficial in applications where a higher surface-to-volume ratio is desirable, such as in catalysts or energy storage devices. Efficiency and Speed: Ultrasonication is a relatively fast process, allowing for efficient dispersion within a short duration. This efficiency is crucial for industrial applications where large quantities of dispersed graphene are needed. Customization: Ultrasonic machines often provide control over parameters such as intensity, duration, and frequency. This allows users to customize the dispersion process based on the specific properties of the graphene and the requirements of the application.   In summary, ultrasonic machines improve dispersion quality by leveraging the cavitation effect and generating intense shear forces that break down graphene agglomerates. This results in a more homogeneous and stable dispersion, contributing to improved material properties and performance in various applications.

Do you understand the Ultrasonic Impact Treatment ?   High Frequency Mechanical Impact (HFMI), also known as Ultrasonic Impact Treatment (UIT ), is a high-frequency weld impact treatment designed to improve the fatigue resistance of welded structures.In most industrial applications this process is also known as ultrasonic peening (UP). It is a cold mechanical treatment that involves striking the weld toe with a needle to create an enlargement of its radius and to introduce residual compressive stresses.       In general, the basic UP system shown could be used for treatment of weld toe or welds and larger surface areas if necessary.           Freely Movable Strikers The UP equipment is based on known from the 40’s of last century technical solutions of using working heads with freely movable strikers for hammer peening. At that time and later, a number of different tools based on using freely movable strikers were developed for impact treatment of materials and welded elements by using pneumatic and ultrasonic equipment. The more effective impact treatment is provided when the strikers are not connected to the tip of actuator but could move freely between the actuator and the treated material. The tools for impact treatment of materials and welded elements with the freely movable strikers that are mounted in a holder are shown. In the case of so-called intermediate element-striker(s) a force of only 30 - 50 N is required for treatment of materials. Sectional view through tools with freely movable strikers for surface impact treatment.   It shows a standard set of easy replaceable working heads with freely movable strikers for different applications of UP.   A set of interchangeable working heads for UP   During the ultrasonic treatment, the striker oscillates in the small gap between the end of the ultrasonic transducer and the treated specimen, impacting the treated area. This kind of high frequency movements/impacts in combination with high frequency oscillations induced in the treated material is typically called the ultrasonic impact.     Technology and Equipment for Ultrasonic Peening The ultrasonic transducer oscillates at a high frequency, with 20-30 kHz being typical. The ultrasonic transducer may be based on either piezoelectric or magnetostrictive technology. Whichever technology is used, the output end of the transducer will oscillate, typically with amplitude of 20 – 40 mm. During the oscillations, the transducer tip will impact the striker(s) at different stages in the oscillation cycle. The striker(s) will, in turn, impact the treated surface. The impact results in plastic deformation of the surface layers of the material. These impacts, repeated hundreds to thousands of times per second, in combination with high frequency oscillation induced in the treated material result in a number of beneficial effects of UP. The UP is an effective way for relieving of harmful tensile residual stresses and introducing of beneficial compressive residual stresses in surface layers of parts and welded elements. In the fatigue improvement, the beneficial effect is achieved mainly by introducing of the compressive residual stresses into surface layers of metals and alloys, decrease in stress concentration in weld toe zones and the enhancement of the mechanical properties of the surface layer of the material.   Industrial Applications of UP The UP could be effectively applied for fatigue life improvement during manufacturing, rehabilitation and repair of welded elements and structures. The UP technology and equipment were successfully applied in different industrial projects for rehabilitation and weld repair of parts and welded elements. The areas/industries where the UP was applied successfully include: Railway and Highway Bridges, Construction Equipment, Shipbuilding, Mining, Automotive and Aerospace.

How to use FEM ANSYS parameter optimization and probability design of ultrasonic welding horn     Foreword With the development of ultrasonic technology, its application is more and more extensive, it can be used to clean tiny dirt particles, and it can also be used for welding metal or plastic. Especially in today's plastic products, ultrasonic welding is mostly used, because the screw structure is omitted, the appearance can be more perfect, and the function of waterproofing and dustproofing is also provided. The design of the plastic welding horn has an important impact on the final welding quality and production capacity. In the production of new electric meters, ultrasonic waves are used to fuse the upper and lower faces together. However, during use, it is found that some horns are installed on the machine and cracked and other failures occur in a short period of time. Some welding horn The defect rate is high. Various faults have had a considerable impact on production. According to the understanding, equipment suppliers have limited design capabilities for horn, and often through repeated repairs to achieve design indicators. Therefore, it is necessary to use our own technological advantages to develop durable horn and a reasonable design method. 2 Ultrasonic plastic welding principle Ultrasonic plastic welding is a processing method that utilizes the combination of thermoplastics in the high-frequency forced vibration, and the welding surfaces rub against each other to produce local high-temperature melting. In order to achieve good ultrasonic welding results, equipment, materials and process parameters are required. The following is a brief introduction to its principle. 2.1 Ultrasonic plastic welding system Figure 1 is a schematic view of a welding system. The electrical energy is passed through the signal generator and the power amplifier to produce an alternating electrical signal of ultrasonic frequency (> 20 kHz) that is applied to the transducer (piezoelectric ceramic). Through the transducer, the electrical energy becomes the energy of the mechanical vibration, and the amplitude of the mechanical vibration is adjusted by the horn to the appropriate working amplitude, and then uniformly transmitted to the material in contact with it through the horn. The contact surfaces of the two welding materials are subjected to high-frequency forced vibration, and the friction heat generates local high temperature melting. After cooling, the materials are combined to achieve welding.   In a welding system, the signal source is a circuit part that contains a power amplifier circuit whose frequency stability and drive capability affect the performance of the machine. The material is a thermoplastic, and the design of the joint surface needs to consider how to quickly generate heat and dock. Transducers, horns and horns can all be considered mechanical structures for easy analysis of the coupling of their vibrations. In plastic welding, mechanical vibration is transmitted in the form of longitudinal waves. How to effectively transfer energy and adjust the amplitude is the main point of design. 2.2horn The horn serves as the contact interface between the ultrasonic welding machine and the material. Its main function is to transmit the longitudinal mechanical vibration outputted by the variator evenly and efficiently to the material. The material used is usually high quality aluminum alloy or even titanium alloy. Because the design of plastic materials changes a lot, the appearance is very different, and the horn has to change accordingly. The shape of the working surface should be well matched with the material, so as not to damage the plastic when vibrating; at the same time, the first-order longitudinal vibration solid frequency should be coordinated with the output frequency of the welding machine, otherwise the vibration energy will be consumed internally. When the horn vibrates, local stress concentration occurs. How to optimize these local structures is also a design consideration. This article explores how to apply ANSYS design horn to optimize design parameters and manufacturing tolerances.   3 welding horn design As mentioned earlier, the design of the welding horn is quite important. There are many ultrasonic equipment suppliers in China that produce their own welding horns, but a considerable part of them are imitations, and then they are constantly trimming and testing. Through this repeated adjustment method, the coordination of horn and equipment frequency is achieved. In this paper, the finite element method can be used to determine the frequency when designing the horn. The horn test result and the design frequency error are only 1%. At the same time, this paper introduces the concept of DFSS (Design For Six Sigma) to optimize and robust design of horn. The concept of 6-Sigma design is to fully collect the customer's voice in the design process for targeted design; and pre-consideration of possible deviations in the production process to ensure that the quality of the final product is distributed within a reasonable level. The design process is shown in Figure 2. Starting from the development of the design indicators, the structure and dimensions of the horn are initially designed according to the existing experience. The parametric model is established in ANSYS, and then the model is determined by the simulation experiment design (DOE) method. Important parameters, according to the robust requirements, determine the value, and then use the sub-problem method to optimize other parameters. Taking into account the influence of materials and environmental parameters during the manufacture and use of the horn, it has also been designed with tolerances to meet the requirements of manufacturing costs. Finally, the manufacturing, test and test theory design and actual error, to meet the design indicators that are delivered. The following step-by-step detailed introduction. 3.1 Geometric shape design (establishing a parametric model) Designing the welding horn first determines its approximate geometric shape and structure and establishes a parametric model for subsequent analysis. Figure 3 a) is the design of the most common welding horn, in which a number of U-shaped grooves are opened in the direction of vibration on a material of approximately cuboid. The overall dimensions are the lengths of the X, Y, and Z directions, and the lateral dimensions X and Y are generally comparable to the size of the workpiece being welded. The length of Z is equal to the half wavelength of the ultrasonic wave, because in the classical vibration theory, the first-order axial frequency of the elongated object is determined by its length, and the half-wave length is exactly matched with the acoustic wave frequency. This design has been extended. Use, is beneficial to the spread of sound waves. The purpose of the U-shaped groove is to reduce the loss of lateral vibration of the horn. The position, size and number are determined according to the overall size of the horn. It can be seen that in this design, there are fewer parameters that can be freely regulated, so we have made improvements on this basis. Figure 3 b) is a newly designed horn that has one more size parameter than the traditional design: the outer arc radius R. In addition, the groove is engraved on the working surface of the horn to cooperate with the surface of the plastic workpiece, which is beneficial to transmit vibration energy and protect the workpiece from damage. This model is routinely parametrically modeled in ANSYS, and then the next experimental design. 3.2 DOE experimental design (determination of important parameters) DFSS is created to solve practical engineering problems. It does not pursue perfection, but is effective and robust. It embodies the idea of 6-Sigma, captures the main contradiction, and abandons "99.97%", while requiring the design to be quite resistant to environmental variability. Therefore, before making the target parameter optimization, it should be screened first, and the size that has an important influence on the structure should be selected, and their values should be determined according to the robustness principle. 3.2.1 DOE parameter setting and DOE The design parameters are the horn shape and the size position of the U-shaped groove, etc., a total of eight. The target parameter is the first-order axial vibration frequency because it has the greatest influence on the weld, and the maximum concentrated stress and the difference in the working surface amplitude are limited as state variables. Based on experience, it is assumed that the effect of the parameters on the results is linear, so each factor is only set to two levels, high and low. The list of parameters and corresponding names is as follows. DOE is performed in ANSYS using the previously established parametric model. Due to software limitations, full-factor DOE can only use up to 7 parameters, while the model has 8 parameters, and ANSYS's analysis of DOE results is not as comprehensive as professional 6-sigma software, and can't handle interaction. Therefore, we use APDL to write a DOE loop to calculate and extract the results of the program, and then put the data into Minitab for analysis. 3.2.2 Analysis of DOE results Minitab's DOE analysis is shown in Figure 4 and includes the main influencing factors analysis and interaction analysis. The main influencing factor analysis is used to determine which design variable changes have a greater impact on the target variable, thereby indicating which are important design variables. The interaction between the factors is then analyzed to determine the level of the factors and to reduce the degree of coupling between the design variables. Compare the degree of change of other factors when a design factor is high or low. According to the independent axiom, the optimal design is not coupled to each other, so choose the level that is less variable. The analysis results of the welding horn in this paper are: the important design parameters are the outer arc radius and the slot width of the horn. The level of both parameters is "high", that is, the radius takes a larger value in the DOE, and the groove width also takes a larger value. The important parameters and their values were determined, and then several other parameters were used to optimize the design in ANSYS to adjust the horn frequency to match the operating frequency of the welding machine. The optimization process is as follows. 3.3 Target parameter optimization (horn frequency) The parameter settings of the design optimization are similar to those of the DOE. The difference is that the values of two important parameters have been determined, and the other three parameters are related to the material properties, which are regarded as noise and cannot be optimized. The remaining three parameters that can be adjusted are the axial position of the slot, the length and the horn width. The optimization uses the subproblem approximation method in ANSYS, which is a widely used method in engineering problems, and the specific process is omitted. It is worth noting that using frequency as the target variable requires a little skill in operation. Because there are many design parameters and a wide range of variation, the vibration modes of the horn are many in the frequency range of interest. If the result of modal analysis is directly used, it is difficult to find the first-order axial mode, because the modal sequence interleaving may occur when the parameters change, that is, the natural frequency ordinal corresponding to the original mode changes. Therefore, this paper adopts the modal analysis first, and then uses the modal superposition method to obtain the frequency response curve. By finding the peak value of the frequency response curve, it can ensure the corresponding modal frequency. This is very important in the automatic optimization process, eliminating the need to manually determine the modality. After the optimization is completed, the design working frequency of the horn can be very close to the target frequency, and the error is less than the tolerance value specified in the optimization. At this point, the horn design is basically determined, followed by manufacturing tolerances for production design. 3.4 Tolerance design The general structural design is completed after all design parameters have been determined, but for engineering problems, especially when considering the cost of mass production, tolerance design is essential. The cost of low precision is also reduced, but the ability to meet design metrics requires statistical calculations for quantitative calculations. The PDS Probability Design System in ANSYS can better analyze the relationship between design parameter tolerance and target parameter tolerance, and can generate complete related report files. 3.4.1 PDS parameter settings and calculations According to the DFSS idea, tolerance analysis should be performed on important design parameters, and other general tolerances can be determined empirically. The situation in this paper is quite special, because according to the ability of machining, the manufacturing tolerance of geometric design parameters is very small, and has little effect on the final horn frequency; while the parameters of raw materials are greatly different due to suppliers, and the price of raw materials accounts for More than 80% of horn processing costs. Therefore, it is necessary to set a reasonable tolerance range for the material properties. The relevant material properties here are density, modulus of elasticity and speed of sound wave propagation. Tolerance analysis uses random Monte Carlo simulation in ANSYS to sample the Latin Hypercube method because it can make the distribution of sampling points more uniform and reasonable, and obtain better correlation by fewer points. This paper sets 30 points. Assume that the tolerances of the three material parameters are distributed according to Gauss, initially given an upper and lower limit, and then calculated in ANSYS.   3.4.2 Analysis of PDS results Through the calculation of PDS, the target variable values corresponding to 30 sampling points are given. The distribution of the target variables is unknown. The parameters are fitted again using Minitab software, and the frequency is basically distributed according to the normal distribution. This ensures the statistical theory of tolerance analysis. The PDS calculation gives a fitting formula from the design variable to the tolerance expansion of the target variable: where y is the target variable, x is the design variable, c is the correlation coefficient, and i is the variable number.   According to this, the target tolerance can be assigned to each design variable to complete the task of tolerance design. 3.5 Experimental verification The front part is the design process of the entire welding horn. After the completion, the raw materials are purchased according to the material tolerances allowed by the design, and then delivered to the manufacturing. Frequency and modal testing are performed after manufacturing is completed, and the test method used is the simplest and most effective sniper test method. Because the most concerned index is the first-order axial modal frequency, the acceleration sensor is attached to the working surface, and the other end is struck along the axial direction, and the actual frequency of the horn can be obtained by spectral analysis. The simulation result of the design is 14925 Hz, the test result is 14954 Hz, the frequency resolution is 16 Hz, and the maximum error is less than 1%. It can be seen that the accuracy of the finite element simulation in the modal calculation is very high. After passing the experimental test, the horn is put into production and assembly on the ultrasonic welding machine. The reaction condition is good. The work has been stable for more than half a year, and the welding qualification rate is high, which has exceeded the three-month service life promised by the general equipment manufacturer. This shows that the design is successful, and the manufacturing process has not been repeatedly modified and adjusted, saving time and manpower. 4 Conclusion This paper starts with the principle of ultrasonic plastic welding, deeply grasps the technical focus of welding, and proposes the design concept of new horn. Then use the powerful simulation function of finite element to analyze the design concretely, and introduce the 6-Sigma design idea of DFSS, and control the important design parameters through ANSYS DOE experimental design and PDS tolerance analysis to achieve robust design. Finally, the horn was successfully manufactured once, and the design was reasonable by the experimental frequency test and the actual production verification. It also proves that this set of design methods is feasible and effective.
