Abstract

The invention discloses a machining method for achieving metal texture of a plastic shell with grain appearance. The method includes the following steps that pretreatment paint is sprayed to the plastic shell with grains; UV primer spraying is conducted on the plastic shell where the pretreatment paint is sprayed in a thin coating mode, and adhesion of a coating film is improved; supplementary coating is conducted on portions with low structural design strength and/or injection molding fusion line positions; non-conductive vacuum evaporation film coating is conducted on the plastic shell where UV primer is sprayed, and a metal-imitating effect is achieved; UV intermediate paint spraying is conducted on the plastic shell subjected to film coating, and UV intermediate paint is colored to meet the color requirement; UV surface paint spraying is conducted on the plastic shell sprayed with the UV intermediate paint so as to adjust the gloss of the plastic shell. The primer thin coating technology and the electroplating technology are combined, on the premise that the performance and the texture effect of the shell are guaranteed, the metal texture effect is achieved on a plastic substrate, and the requirements of customers for economical efficiency and appearance metal texture are met.

Description

technical field [0001] The invention relates to the technical field of manufacturing process of a product shell, in particular to a processing method for realizing a metal texture on a plastic shell with a textured appearance, and a plastic shell that realizes a metal texture by using the method. Background technique [0002] The shell of the product, especially the shell of the mobile phone, is gradually developing towards the design direction of the metal shell, which can improve the aesthetics of the product appearance, and then improve the product quality. [0003] Most of the metal shells are made of stainless steel and aluminum, and the material cost is relatively high. For low-cost products, the housing is mainly made of plastic, but consumers prefer metal bright edges, metal wire drawing, metal sandblasting, etc. that can reflect metal features and have a certain texture. Therefore, it is necessary Develop a low-cost method to realize the texture and metal texture e...
