Vertical ultrasonic spraying machines are widely used to apply coatings on mobile phone housings. Compared with conventional coating methods, ultrasonic spraying produces finer, more even coating layers. This helps cut material consumption and boost overall production efficiency, which is why many leading handset makers have rolled out this technology on their production lines.

 

Within the mobile phone manufacturing sector, vertical ultrasonic spraying equipment for phone housings will see broader and deeper adoption going forward. Beyond housings itself, ultrasonic spraying can also treat other phone parts such as metal mid-frames and glass back covers, enhancing the surface feel and visual finish of final products. With ongoing process refinement and falling operating costs, ultrasonic spraying is poised to emerge as one of the dominant coating processes in mobile phone mass production.

 

 

 

1. Ultrasonic Power Supply

The spraying system comes with an ultrasonic power supply. It converts electric energy into high-frequency mechanical vibration.

 

2. Liquid Feed

Spray materials with viscosity under 30 cps travel through dedicated tubing to the nozzle, where ultrasonic vibration breaks the liquid into fine atomized droplets.

 

3. Spraying Operation

These finely atomized droplets leave the nozzle and settle evenly over mobile phone housing surfaces, building up a uniform coating film.

 

4. Curing & Drying

The freshly applied coating can cure through natural air drying or thermal heating. This creates a tough protective outer layer on the workpiece.

 

 

 

1. Ultrasonic Spraying on Xiaomi Smartphone Housings

Xiaomi's 2022 flagship smartphone uses ultrasonic spraying to coat its metal mid-frame. The process produces a finer, more consistent coating finish. It elevates both the phone's visual look and hand feel, while helping raise production efficiency and yield stability.

 

2. Ultrasonic Spraying for OPPO Find X3 Camera Modules

OPPO adopted ultrasonic spraying for surface treatment on camera modules of its 2022 Find X3 series. The technology yields an ultra-smooth, evenly finished surface on the camera module and greatly enhances the handset's dustproof and waterproof performance.
