Injection part surface treatment process

Abstract

The invention discloses an injection part surface treatment process. The process comprises the following steps: spraying, coating a titanium metal layer, screen printing, electroplating and injection molding. A product treated by using the injection part surface treatment process disclosed by the invention has the remarkable effects of high corner angle and high stereoscopic impression in surface, better appearance, good hardness, wear-resisting property, chemical erosion resistance and ultraviolet resistance conforming to the corresponding standard and can be widely applied to plastic shells of cell phones, panel personal computers and other consumer electronics.

Description

Technical field [0001] The invention relates to a surface treatment process for injection molded parts. Background technique [0002] With the continuous improvement of people's living standards, consumer electronic products such as mobile phones and tablet computers have become more and more popular. On the basis of increasingly powerful functions, the texture of the plastic shell and the three-dimensional sense of the pattern have become more and more consumers' choice. index of. At present, there are many problems when painting the plastic shell of the product: (1) The spray paint layer is too thick; (2) The spray paint particles are too thick; (3) The spray paint uniformity is poor; (4) The wear resistance is poor; (5) Spray paint There are dead corners; (6) the use of spray paint substrate; (7) spray paint affects the strength of the material; (8) dirty spots on the spray paint surface. [0003] In addition, the three-dimensional effect of the plastic shell is not good, the ...

Problems solved by technology

At present, there are many problems in the process of painting the plastic shell of the product: (1) the paint layer is too thick; (2) the paint particles are too thick; (3) the paint uniformity is poor; (4) the wear resistance is poor; (5) the paint There are dead corners; (6) The application of the painted substrate; (7) The strength of the material is affected by the sprayed paint; (8) Dirty spots on the painted surface

[0003] In addition, when making three-dimensional effects on plastic shells, the effect is not good, the three-dimensional effect is not strong, and sharp corners and angular structures cannot be processed, which has obvious limitations, is not suitable for mass production, and has defects such as low efficiency.
