by:Jolly     2021-12-08


Mobile phone cases are generally divided into metal and plastic materials. In the process of producing plastic phone cases, iml mobile phone case factories generally need to be sprayed after injection molding.



The spraying of mobile phone shells is divided into manual spraying and automatic spraying. Nowadays, large-scale mobile phone shell manufacturers use automatic spraying production lines for spraying processing. For example, Shenzhen Volkin is equipped with a 315-meter dust-free automatic Spraying line. In the process of spraying, there are generally primers and topcoats. In order to achieve a high level of color, gloss and wear resistance on the surface of the processed mobile phone case, the thickness of the spray must be controlled. The primer is thinner, generally 3~ 5μm; The thickness of the topcoat is generally 8~10μm.



After a series of spraying processes, the mobile phone case manufacturer conducts abrasion resistance test on the final mobile phone case wholesale, and after passing the test, it can be officially mass-produced.
