Sonaer ultrasonic spray nozzle by Sonia Corporation - Case Study Included (0002)

Case study of the Sonia Corporation's ultrasonic spray nozzle (0002) This time, it is about the thin film coating of stents. To create fine liquid droplets, a lot of energy is required. For example, a two-fluid spray nozzle that combines liquid pressure and air pressure. Even if the droplets are fine, if they have velocity, it can lead to poor coating efficiency and yield. The solution to this problem is the ultrasonic spray nozzle. Ultrasonic vibrations from piezoelectric ceramics are transmitted to the spray nozzle, causing the liquid film to vibrate, forming fine droplets, and then spraying them. Since no pressure is applied to the liquid, the droplet particles have no speed. As a result, there is very little scattering or rebound, and the liquid being applied is sprayed without waste.
