Pretreatment of the surface of the plastic shell; vacuum plating or spray coating the surface of the plastic shell to make the surface of the plastic shell appear bright and shiny;
The mobile phone market is becoming more and more life-like, and intelligence has stepped into our every moment. People are becoming more and more rigorous about the functions and appearance of mobile phones. Mobile phones with metal frames have texture and beauty. At the same time visually make the fuselage look thinner and more beautiful. High-quality laser marking and packaging technology is becoming more and more mature. At present, beyond laser, it can realize the processing process of bright fog and homogeneity on the surface of plastic shells; it includes the following steps:
1. Pre-treatment of the surface of the plastic shell; vacuum plating or spray coating on the surface of the plastic shell to make the surface of the plastic shell appear shiny;
2. Pretreatment of the surface of the plastic shell; on the surface of the plastic shell, select the bright surface parts that need to be processed, and install a suitable fixture to block the bright surface parts that do not need to be processed, and then, Surface parts are etched or etched or hardened;
3. Spray painting treatment; spray painting treatment on the parts after corrosion or etching or hardening treatment;
4. Disassembly jig; after the matte surface formed above is cured and formed, disassemble the jig; the processing process for realizing bright fog and homogeneity on the surface of the plastic shell provided by the present invention enables the bright fog and homogeneity on the surface of the plastic shell Effect, simple processing technology, fast and convenient operation, and low production cost.
