Ultrasonic spraying system for small scale coating and research processes

Ultrasonic spraying technology has the ability to create a thin and uniform nanoparticle coating using a low-velocity spray that realizes a precise targeted spray pattern. The low speed allows for a gentle touch and high controllability of the spray that will lower the waste of expensive material. There are even ultrasonic spraying systems suitable for scientific research institutions and for manufacturers with small volume production.

Benchtop system for creating uniform coating on fuel cells

With the UAM4000L, Cheersonic developed a solution that creates a coating using ultrasound technology. The system meets market needs in a wide range of industries and applications for the spraying of glass (e.g., optical lenses, electrochromic glass, flat panel displays or oleophobic coating), fuel cells, solar cells, sensors, PCB (Printed Circuit Board), semiconductors and photoresists.

The machine is provided with a syringe pump that moves the liquid to the ultrasonic nozzle that vibrates longitudinally. Ultrasonic technology converts high-frequency sound waves to mechanical energy, forming standing waves on the tip of the spray nozzle. When the liquid comes out of the nozzle, waves are separated into small droplets. As they reach a critical amplitude, the liquid is sprayed out as a mist. Compared to conventional technology based on pressure nozzles, the ultrasonic coating system has the ability to deposit droplets in a very gentle and accurate way on the substrate due to a low-pressure and low-velocity spray. By using very little pressure, the nozzle doesn’t clog, and the drops bouncing effect is eliminated.

Benefits

  • Customized nozzle heads according to the substance process requirements
  • Reduced overspray
  • Reduced downtime thanks to non-clogging nozzles
