Fabrication method of metal housing

Abstract

The invention provides a fabrication method of a metal housing. The method comprises the steps as follows: (1) a shell (1) is provided; the shell (1) is formed through a stamping process; and a pre-treatment process is carried out on the shell (1); (2) a structure reinforcer (2) is provided; the structure reinforcer (2) is an aluminum die casting; and the structure reinforcer (2) is combined in the shell (1) as a reinforcing structure; (3) a sand blasting process is carried out on the shell (1); and (4) an anodization process is carried out on the shell (1). The aluminum die casting is combined in the shell as the reinforcing structure, so that deformation of the shell in the sand blasting process is effectively reduced; and the obtained product is good in consistency and high in accuracy; the yield of a product is improved; the aluminum die casting in the sand blasting process can replace a sand blasting tool for protection; the production cost is saved; meanwhile, the corrosion influence on the structure reinforcer caused by a strong acid or alkali in the anodization process can be avoided; and the quality of the product is ensured.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a method for manufacturing a metal shell. Background technique [0002] With the rapid development of related technologies of electronic products, people have higher and higher requirements for electronic products. Metal alloys such as aluminum alloys are widely used in structures such as housings of electronic products due to their high strength and high-tech appearance. [0003] Under the trend of ultra-light and thin appearance of electronic products, the products need to be made thinner and thinner, which leads to easy deformation during the processing of the products. In order to overcome product deformation, some manufacturers directly process aluminum materials through CNC (Computer Numerical Control, CNC machine tools) and make various structures internally. However, the products produced by this method are relatively thick, the cost is relatively high, and the production...

AI Technical Summary

Problems solved by technology

However, in order to make the product thinner, the product will easily produce technical problems of deformation during the sandblasting process

Since the stamping parts are easily deformed during the sandblasting process, sandblasting fixtures need to be added to protect the product from deformation, which causes an increase in the cost of the process; and the product consistency obtained after the sandblasting process is relatively low. Poor, resulting in poor product yield

In addition, when plastic parts or magnesium-aluminum alloy parts are used as the reinforcement structure of stamping parts, during the anodic treatment process, the plastic parts or magnesium-aluminum alloy parts will be corroded by strong acid or alkali, resulting in defective products
