The vertical ultrasonic spraying machine for mobile phone housings is widely adopted for coating mobile‑phone casings. Ultrasonic spraying delivers more uniform, fine‑grained coatings, which reduces material waste and improves production efficiency. Major mobile‑phone manufacturers have started integrating this technology into their production lines.

The adoption of vertical ultrasonic spraying equipment for mobile‑phone housings will continue to expand and deepen within the mobile‑phone manufacturing industry. Ultrasonic spraying can be applied to more mobile‑phone components including metal frames and glass back covers, to improve surface texture and visual quality of finished phones. Furthermore, as processes keep getting optimized and costs are further lowered, ultrasonic spraying is expected to become one of the mainstream process technologies for mobile‑phone manufacturing.

 

 

 

1. Ultrasonic power supply
The spraying system is equipped with an ultrasonic power supply, which converts electrical energy into high‑frequency mechanical vibration.

2. Liquid feeding
Spray materials with viscosity below 30 cps are delivered to the nozzle via a dedicated pipeline, where they are atomized by ultrasonic vibration.

3. Spraying process
Well‑atomized fine droplets exit the nozzle and deposit onto the surface of phone housings to form a homogeneous coating layer.

4. Curing and drying
The deposited coating is cured either by ambient air‑drying or thermal heating, yielding a hard protective outer layer on the substrate.

 

 

 

1. Ultrasonic Spraying for Xiaomi Smartphone Housings Xiaomi's 2022 flagship smartphone adopts ultrasonic spraying technology for the treatment of its metal middle frame, delivering a more refined and evenly distributed coating finish. This process not only upgrades the device's visual aesthetics and tactile texture but also effectively boosts production efficiency and yield consistency.

 

2. Ultrasonic Fingerprint Recognition for Samsung Galaxy Series Launched in 2021, Samsung Galaxy S21 series devices feature an integrated in-body ultrasonic fingerprint recognition solution. Compared with traditional optical fingerprint technology, this ultrasonic solution offers higher security and stability, and performs reliably in complex scenarios such as humid and wet environments.

 

3. Ultrasonic Processing for OPPO Find X3 Camera Modules The 2022 OPPO Find X3 series applies ultrasonic spraying technology to its camera module surface treatment. The technology creates an ultra-smooth, uniform surface finish for the camera module, while significantly improving the device's overall water and dust resistance.
