[0028] Method Example 1
[0029] A surface treatment method of an electronic product housing includes the following steps:
[0030] 1) Spray primer on the shell surface; the primer is UV transparent paint (Ultraviolet Curing Paint, called ultraviolet curing paint), the thickness of the primer is 25-30um, the baking temperature is 55±5°, and the baking energy of UV paint is 600 -800mj / cm2.
[0031] 2) A metal coating is formed on the primer by vacuum coating; the vacuum coating adopts the NCVM process (Nonconductive vacuum metallization, called non-conductive vacuum plating). The vacuum coating is to dissolve the target material to be plated by direct heating or indirect heating under vacuum conditions, and then evaporate, or directly sublimate the solid into a gas, and atoms or molecules with sufficient energy fly to and deposit on the bottom On the lacquer surface, a metal film of a certain thickness is deposited.
[0032] 3) The texture is formed by laser engraving on the metal co...

[0042] 1) Spray primer on the shell surface; the primer is UV transparent paint, the thickness of the primer is 25-30um, the baking temperature is 55±5°, and the baking energy of UV paint is 600-800mj / cm2.
[0043] 2) A metal coating is formed on the primer by vacuum coating; the vacuum coating adopts the NCVM process. The vacuum coating is to dissolve the target material to be plated by direct heating or indirect heating under vacuum conditions, and then evaporate, or directly sublimate the solid into a gas, and atoms or molecules with sufficient energy fly to and deposit on the bottom On the lacquer surface, a metal film of a certain thickness is deposited.
[0044] 3) Spraying the medium paint on the metal plating film, the medium paint being UV transparent paint, the thickness of the medium paint is 3-5um, the baking temperature is 55±5°, and the baking ene...
