Stereoscopic plastic piece surface treatment technology

Abstract

The invention discloses a stereoscopic plastic piece surface treatment technology. The technology comprises the steps of spraying, titanium metal layer coating, screen painting, electroplating and injection molding. A product obtained after processing through the injection molded product treatment technology has the advantages of substantial highly-angular and highly-stereoscopic effects, beauty, and good hardness, has wear, chemical corrosion and UV resistances according with corresponding standards, and can be widely used in plastic shells of mobile phones, panel computers and other consumer electronics.

Description

technical field [0001] The invention relates to a surface treatment process of plastic parts with three-dimensional effect. 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 effect of the pattern have increasingly become the choice of consumers. index of. 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.

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.
