Embodiment 1

[0022] Using the manufacturing method of an aluminum alloy appearance part provided by the present invention, the production of an aluminum alloy appearance part with anodic color effect, metallic high-gloss texture, unidirectional gradient color and lubricating hand feeling at the same time includes the following steps:

[0023] Stamping forming: According to the appearance design specifications of the product, the aluminum alloy bright panel is used to stamp and form aluminum alloy appearance parts;

[0024] Degreasing: Use calcium carbonate and calcium phosphate alkaline degreasing agent to degrease the aluminum alloy exterior parts to remove oil stains on the surface. During the degreasing process, the alkaline degreasing agent is at 55°C and the treatment time is 5 minutes;

[0025] Anodizing: The formed aluminum alloy appearance part is used as an anode, put into an oxidation tank, energized, and anodized. The treatment liquid used in anodized treatment is a mixed solutio...

Embodiment 2

[0031] Using the manufacturing method of an aluminum alloy appearance part provided by the present invention, the production of an aluminum alloy appearance part with anodic color effect, metallic high-gloss texture, two-way gradient color and lubricating hand feeling at the same time includes the following steps:

[0032] Stamping forming: According to the product's appearance design specifications, the aluminum alloy bright panel is used to stamp and form aluminum alloy appearance parts.

[0033] Degreasing: use calcium carbonate and calcium phosphate alkaline degreasing agent to degrease the aluminum alloy exterior parts to remove oil stains on the surface. During the degreasing process, the alkaline degreasing agent is at 55°C and the treatment time is 5 minutes.

[0034] Anodizing: The formed aluminum alloy appearance part is used as an anode, put into an oxidation tank, energized, and anodized. The treatment liquid used in anodized treatment is a mixed solution of formic ...

Abstract

The invention provides a manufacturing method of an aluminum alloy appearance piece, and the method is characterized by mainly comprising the steps of: (1) press-molding; (2) degreasing; (3) anodic oxidation; (4) dyeing; and (5) hole sealing. Compared with the prior art, the manufacturing method of an aluminum alloy appearance piece of the invention has the following advantages that: the product has an anode color effect, metal highlight texture, as well as an appearance effect of gradient color change; due to the employment of anodic oxidation surface treatment, the product surface is difficult to drop and rust, and the color always seems like new; the product has a surface with high abrasion resistance, and mild and smooth handfeel; and the method provides diversified product appearance choices for industrial design, and can meet more consumption demands. The manufacturing method of an aluminum alloy appearance piece of the invention can be used for producing the appearance pieces of various 3C products, especially laptops, tablet personal computers, mobile phones and digital audio and video players, etc.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing an aluminum alloy appearance part, in particular to a method for manufacturing an aluminum alloy appearance part with anodic color effect, metal high-gloss texture, gradient color change and lubricated appearance effect. 【Background technique】 [0002] Today, people are increasingly pursuing high-quality life, and people are paying more and more attention to the shape and appearance of household products, so the appearance of 3C products is becoming more and more colorful. At present, the development trend of 3C products is to develop in the direction of light and thin. Light metal stamping parts, especially aluminum alloy stamping parts, are more and more widely used in the shell of 3C products. [0003] At present, aluminum alloy appearance parts with various appearance effects have appeared on the market, but there is no aluminum alloy appearance part with anodic color effect, metal high-gloss te...
