35khz Portable Ultrasonic Welding Equipment Ultrasonic Spot Welder

Introduction:

Why we use ultrasonic spot welding equipment to replace the traditional welding equiopment,there are some common problems with traditional welding:

1. High-temperature welding is easy to cause damage to the welding surface, and the product will be deformed in severe cases.

2. The welding equipment is bulky, not easy to handle by hand, and unable to complete complex procedures.

3. The welding mode is too single, the welding material is restricted, and the welding horn cannot be replaced at will.

4. Adhesives and fluxes are used for welding, the welding pollution is serious, and the welding strength is not high.

5. Adhesive, buckle or other mechanical fixation is used during welding, which has low efficiency and high cost.

When ultrasonic energy are applied to the surface of thermoplastics, high-frequency vibrations of tens of thousands of times per second are generated. The ultrasonic energy is transmitted to the welding zone through the weldment and local high temperatures are generated. Due to the poor thermal conductivity of plastic, heat is accumulated in the welding zone, which causes the plastic surface to melt rapidly, and after a certain pressure is added, it is integrated into one.

Handheld ultrasonic spot welder can be used for welding, riveting, spot welding of film, cloth, thermoplastic products, as well as the inlaying and blanking process between metal and plastic parts.

Advantages:

1. High stability: The digital electric box automatically tracks the resonance frequency and adjusts the output frequency to match the handheld device. Once a fault is found, the work stops and the alarm is issued, and most of the ultrasonic welding can be completed within 0.1-0.5 seconds.

2.Energy saving and environmental protection: the welding surface is not damaged and deformed, no scratches and glue residues, no need to use a large number of fixtures, flux, glue, reduce labor and reduce costs.

3. Reliable quality: solidified by ultrasonic welding, recombination between molecules to form a strong molecular chain, the strength of the weld can be close to the strength of the raw material, good air tightness, no water leakage, and no air permeability.

4. Simple operation: Ultrasonic welding is very easy to automate. As long as the welding parameters are set, welding can be performed without pre-heating and cleaning.

5.Wide range of applications: Handheld ultrasonic spot welders can be used for welding, riveting, spot welding of films, cloths, and thermoplastic products, as well as inlaying and blanking processes between metal and plastic parts.

Application:

ultrasonic spot welding equipment mainly used in two major areas: home appliances and automotive interior decoration. 

Specifics include: car door panels, car sound insulation boards, car interior trim parts, car sound insulation cotton, TV casings, computer casings, electrical plastic trims, etc. Detailed processes and materials: applicable to ABS, PP, PE, PC, PUC, PMMA, PS, PPS, PBT, PETG and other plastic spot welding, pressure welding, riveting and chain welding processes.
