Abstract

The invention relates to a method of manufacturing a metal shell, the metal shell and a terminal and belongs to the field of a mechanical design. The method comprises carrying out primary polishing treatment on a metal base to obtain a surface treatment layer, forming an anodic oxide layer with a plurality of micropores on the metal base with the surface treatment layer, carrying out pore half-sealing treatment on the anodic oxide layer so that each one of the micropores is partially closed, forming a transparent paint layer on the anodic oxide layer subjected to the pore half-sealing treatment, and carrying out secondary polishing treatment on the transparent paint layer. The method solves the problem that the metal base fading results in low color saturation of the surface of the metal shell and the surface of the metal shell has high roughness. The method guarantees the color saturation of the surface of the metal shell and reduces metal shell surface roughness. The method is applied to manufacture the metal shell.

Description

technical field [0001] The disclosure belongs to the field of mechanical design, and in particular relates to a method for manufacturing a metal shell, the metal shell and a terminal. Background technique [0002] In recent years, mobile terminals with metal shells have become more and more popular. Since a variety of colors can be formed on the surface of aluminum alloy, mobile terminals with metal shells made of aluminum alloy are especially favored by consumers. [0003] In the related art, there are two common manufacturing methods for the metal shell made of aluminum alloy. The first method is to sequentially anodize and polish the metal base to obtain the metal shell; the second method is to first The base is polished, and then anodized, and an anodized layer is formed on the surface of the anodized metal base, and the metal base with the anodized layer is sequentially dyed, sealed and baked to obtain a metal shell. Hexagonal columnar micropores are formed on the anod...
