Abstract

The invention provides a manufacturing method of an aluminum alloy appearance part, which is characterized by mainly comprising the following steps of: (1) punch-forming; (2) degreasing; (3) electrolytic grinding; (4) stripping; (5) anodizing; and (6) hole sealing. Compared with the prior art, the manufacturing method of the aluminum alloy appearance part has the following advantages that a product has high glaze and also has the metal mirror texture appearance; the formula is environmental-friendly, and the anodizing surface treatment is adopted, so that the surface of the product is not easy to fall off and rust and is always new in color and luster; and various dyeing and other manufacturing processes can be matched, the diversified product appearance is provided, and more appearance design requirements are satisfied.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing an appearance part, in particular to a method for manufacturing a high-gloss mirror aluminum alloy appearance part that adopts electrolytic grinding treatment and anodic oxidation treatment. 【Background technique】 [0002] Existing electronic products, such as mobile phones, MP3 players, digital cameras, notebook computers, tablet computers, and digital plotters, all pursue fashionable and beautiful product appearances. At present, these electronic products usually use plastic shells, and through processes such as vacuum sputtering or in-mold transfer printing, the products have a bright metallic appearance and give people a visual impact. The appearance parts of electronic products processed in this way, after a period of use, the film layer on the outer surface is easy to peel off, lose luster, and the appearance becomes very unattractive. [0003] Chinese patent CN200510035990.3 discloses a proc...
