Embodiment 1

[0031] figure 1 It is a structural schematic diagram of the material tape of the mobile phone back cover provided by the present embodiment; figure 2 It is a structural schematic diagram of the finished product of the mobile phone back cover provided by this embodiment. A method for processing the back cover of a stainless steel mobile phone, the method at least includes the step of etching and reducing weight on the material belt 1 of the back cover of the mobile phone, which is used to reduce the weight of the back cover of the mobile phone and improve the bonding force of in-mold injection molding, wherein the mobile phone The material strip 1 of the back cover is made of 0.4-0.8mm stainless steel, the etching depth of the material strip 1 of the mobile phone back cover is 0.2-0.5mm, and the material thickness of the material strip 1 of the mobile phone back cover can be thicker or thicker according to actual needs. For thinner stainless steel materials, the etching depth...

Embodiment 2

[0043] This preferred embodiment discloses a method for processing the back cover of a stainless steel mobile phone, which is basically the same as the first preferred embodiment. The method at least includes the step of etching the material tape of the mobile phone back cover to reduce the weight of the mobile phone back cover and improve the bonding force of in-mold injection molding, wherein the material tape of the mobile phone back cover is selected as 0.4-0.8mm Made of stainless steel, the etching depth of the tape on the back cover of the mobile phone is 0.2-0.5mm.

[0044] The difference is that the weight reduction step of etching can be carried out before stamping, or after the rough machining or surface treatment of CNC machine tools, which can reduce the weight of the back cover of the mobile phone and improve the plasticity of the in-mold injection molding process. The bonding force with the back cover of the mobile phone is sufficient.

Abstract

The invention discloses a machining method for a stainless steel mobile phone rear cover, belongs to the field of machining methods for mobile phone parts, and aims to solve the problems of high machining cost, lower strength and the like of the conventional mobile phone rear cover. The machining method at least comprises the step of etching a material strip of the mobile phone rear cover to reduce the weight of the mobile phone rear cover. The step is used for reducing the weight of the mobile phone rear cover and improving the binding force of intra-mold injection, the material strip of the mobile phone rear cover is made of a stainless steel material of 0.4-0.8mm, and the etching depth of the material strip of the mobile phone rear cover is 0.2-0.5mm. According to the machining method, the machining procedure is simple, and the machining cost is lower. The mobile phone rear cover machined according to the method is attractive, elegant and higher in strength.

Description

technical field [0001] The invention relates to the field of processing methods for mobile phone parts, in particular to a processing method for the back cover of a stainless steel mobile phone. Background technique [0002] Mobile phones have gradually become one of the necessities of modern people's life and play an important role in modern people's lives. Therefore, various factors such as the overall aesthetics of the mobile phone, the firmness of the mobile phone screen and back cover, and manufacturing costs require mobile phone manufacturers. Gradually improve. [0003] Existing mobile phone back covers are usually made of aluminum or plastic materials using traditional processing methods. The back covers made of these two materials have low strength, high manufacturing costs, and unattractive appearance. Therefore, the overall cost of the mobile phone is reduced. service life and aesthetics. Contents of the invention [0004] The object of the invention is to pro...
