AI Technical Summary

Problems solved by technology

Usually, if the shell made of a single metal material is not supplemented with surface treatment such as baking paint and electrophoretic coating, the color and visual effect of the shell will be relatively simple, and it is difficult to improve the appearance competitiveness and added value of the product
If the metal shell is supplemented with surface treatment such as baking paint and electrophoretic coating, the metal texture of the shell will be reduced.

Embodiment Construction

[0013] The manufacturing method of the shell of a preferred embodiment of the present invention comprises the following steps:

[0014] A metal base is provided. The metal base can be made of stainless steel.

[0015] A plurality of grooves are etched on a partial area of ​​a surface of the metal base. The several grooves can be patterns with regular shapes or random patterns. The depth of the grooves can be between 0.1-0.12mm. The method for etching some grooves can be chemical etching, such as the metal substrate can be immersed in an etching solution containing copper ions, iron ions, chloride ions, sulfate ions and nitrate ions, and the metal ions in the etching solution A chemical reaction occurs with the area to be etched on the surface of the metal substrate to achieve the etching effect. The area on the surface of the substrate that does not need to be etched can be shielded by film masking.

[0016] Roughening treatment is performed on the plurality of grooves. ...

Abstract

The invention provides a shell making method and a shell made by the same. The making method comprises the following steps of: providing a metal matrix; etching a recess in part area of the metal matrix; covering a metal layer on the surface of the matrix and the recess; and removing the metal layer formed on the matrix surface. The shell comprises a metal matrix, wherein the recess is formed on a surface of the metal matrix, and the metal layer covers the surface of the recess.

Description

technical field [0001] The invention relates to a manufacturing method of a shell and a shell made by the method. Background technique [0002] The casings of existing electronic products are usually made of plastic or metal. Because the metal casing has the characteristics of high strength and noble appearance, electronic products with metal casings are more favored by consumers. Usually, if the shell made of a single metal material is not supplemented with surface treatment such as baking paint and electrophoretic coating, the color and visual effect of the shell will be relatively simple, and it is difficult to improve the appearance competitiveness and added value of the product. If surface treatments such as baking paint and electrophoretic coating are supplemented to the metal shell, the metallic texture of the shell will be reduced again. Contents of the invention [0003] In view of this, it is necessary to provide a method for manufacturing a metal texture shell...
