Abstract

The invention relates to a plastic part metalizing process with a hardware nanometer molding artwork line effect. The plastic part metalizing process comprises the following steps: step 1, taking a plastic base material, spraying priming paint on the surface of the plastic base material, baking, and thus obtaining a priming paint layer; step 2, spraying protective paint on the surface of the priming paint layer, baking, and thus forming a protective paint layer; step 3, spraying imitated anodized paint on the surface of the protective paint layer, baking, and thus forming a imitated anodizedpaint layer; and step 4, spraying cover paint on the surface of the imitated anodized paint layer, covering, and forming a cover paint layer. Thus, the shell of a mobile communication terminal has a good metal texture effect, the adhesive force between each coating and the plastic base material is good, and abrading and peeling are not easy. In addition, as a non-metallic material is used as the base material, the surface treatment steps of T treatment, nanometer molding, polishing, sand blasting, etc., are not needed, the processing technology is simplified, the production cycle is shortened,and further the production efficiency is improved. Moreover, the waste and overuse of metal materials are reduced.

Description

technical field [0001] The invention relates to the field of surface treatment technology of plastic devices, in particular to the metallization process of plastic parts with the effect of metal nano-injection molding lines. Background technique [0002] Metallized electronic product casings with a metallic feel, such as mobile phone casings, are mainly processed by metal materials. There are two main processing techniques: [0003] The first method: take metal material, die-casting molding—CNC hole processing—T treatment (heat treatment)—first cleaning—nano injection molding—polishing—second cleaning—sandblasting—first anodizing—CNC (high light)—second anodizing ; [0004] The second method: take metal aluminum material, split aluminum material - CNC hole processing - T treatment - first cleaning - nano injection molding - polishing - second cleaning - sandblasting - first anodizing - CNC (high gloss) - second anodizing. [0005] The above-mentioned processing technology ...
