Do you know what is the ultrasonic spray coating machine?

Ultrasonic spraying technology is reshaping the face of medical manufacturing. This innovative technology uses high-frequency ultrasonic energy to transform liquids into uniform micron-sized droplets, providing unprecedented precision coating solutions for medical device manufacturing. As the medical industry's requirements for precision and reliability continue to increase, ultrasonic spraying technology has shown unique advantages and has become an important force in promoting the advancement of medical technology.

The core of the ultrasonic spraying system is the ultrasonic generator, transducer and atomizing nozzle. When the system is working, the ultrasonic generator generates a high-frequency electrical signal, which is converted into mechanical vibration through the transducer, causing the nozzle tip to generate high-frequency vibration. When the liquid flows through the vibrating surface, it is broken into uniform micron-sized droplets, forming a precisely controllable spray.

Compared with traditional spraying technology, ultrasonic spraying has significant advantages. It can produce droplets with uniform particle size distribution, and the minimum droplet diameter can reach less than 10 microns. The spray angle and flow rate can be precisely controlled, and the coating uniformity is significantly improved. At the same time, this technology has high atomization efficiency, and the material utilization rate can reach more than 95%, which is much higher than the 30-40% of traditional spraying.

In the field of medical manufacturing, ultrasonic spraying technology shows unique applicability. It can handle liquids of various viscosities, including drug solutions, biomaterials and nanosuspensions. The gentle atomization process will not destroy the activity of drugs, which is particularly suitable for the spraying of biological agents.

In the manufacture of tissue engineering scaffolds, ultrasonic spraying technology provides an innovative solution for biomaterial coating. It can evenly coat the surface of the scaffold with extracellular matrix proteins, growth factors and other bioactive substances to promote cell adhesion and proliferation. This precise coating technology significantly improves the biocompatibility and functionality of tissue engineering scaffolds.

In the application of antibacterial coatings, ultrasonic spraying technology shows great potential. It can evenly coat antibacterial agents such as silver ions and antibiotics on the surface of medical devices to form a durable antibacterial protective layer. In products such as catheters and orthopedic implants, this technology significantly reduces the incidence of hospital infections.
