Ultrasonic Automotive Manufacturing Coating Spray
Protective hard coatings and functional coating films in automotive manufacturing
Ultrasonic atomization spraying is very suitable for the manufacturing of coatings in the automotive industry, and is suitable for applications such as protective hard coatings and functional coating films in automotive manufacturing. Replace wasteful immersion and pressure spray gun processes with unobstructed ultrasonic spraying. Provide excellent uniform flux coverage while significantly reducing flux consumption, lowering maintenance requirements, and minimizing overspray. Ultrasonic atomization spraying has been successful in various paint flux formulations, including standard brazing flux. All reports show a 60% reduction in coating and flux consumption, while reducing maintenance by over 90%.
Compared with traditional pressure spray, the non clogging performance of FUNSONIC ultrasonic nozzle is a significant and direct technological advantage. The unique atomization spray produced by using the ultrasonic nozzle can significantly improve the spray efficiency. Unlike pressure nozzles, ultrasonic nozzles do not use high pressure to force liquid through very small holes. On the contrary, using large pores and high-frequency vibration is used to atomize the liquid into uniform micrometer sized droplets.
Compared with other application methods, one of the main advantages of ultrasonic spray is the fragmentation of agglomerated particles when the suspension moves downward along the nozzle body. During the whole spray process, the liquid will be subject to continuous ultrasonic vibration, so that the suspension can be deposited more effectively and evenly. And because it is a closed spraying process, there is no need to worry about outdoor drying of the flux/adhesive mixture during the process.
Common automotive industrial components manufactured using ultrasonic spraying technology include:
1. Windshield
2. Console panel and dashboard components
3. Lens and headlights
4. Fabric
5. Touch screen
6. Head up Display (HUD)
7. Mirror components
