Ultrasonic spraying is the use of ultrasonic vibration to generate capillary wave atomization function, which atomizes the liquid flowing through the working end of the ultrasonic nozzle to produce micron-sized droplets; adding appropriate pressure gas to make the mist particles more fragmented and homogenized under the action of airflow At the same time, it guides the running direction of the atomized particles and increases the running power of the atomized particles, so as to achieve the purpose of precision spraying on the surface of the object to be coated. After years of research and development, there are now fuel cells, medical stents, balloon surface drugs, thin-film solar cells and metal film electrodes.

Ultrasonic atomization has fine particles, high surface activity, and proper adjustment of the drainage air pressure, which can be well absorbed on the surface of the sprayed object, with little rebound and splash loss, ensuring the uniformity of the sprayed object and the utilization rate of the material (95%-99%)
