Method for preparing terminal shell, terminal shell and mobile terminal

Abstract

The invention discloses a method for preparing a terminal shell, the terminal shell and a mobile terminal. The method for preparing the terminal shell comprises the steps that a coating layer is formed on the outer surface of a shell substrate through a vacuum electroplating method; a protection film is formed on the coating layer; the shell substrate with the protection film is pressed or heat-formed, so that the shell substrate has the preset shape; a color gradient layer is formed on the inner surface of the formed shell substrate; the shell substrate with the color gradient layer is processed, and the terminal shell is obtained. Therefore, cracking and falling caused by high temperature or high pressure to the color gradient layer in the shell forming process can be avoided, the methodis simple, the shell preparation effect is good, and the yield is high.

Description

technical field [0001] The present application relates to the technical field of terminal casing preparation, and in particular to a method for preparing a terminal casing, a terminal casing, and a mobile terminal. Background technique [0002] With the development of mobile communications, the popularity of smart phones is getting higher and higher, and their functions are becoming more and more powerful, and the requirements for the aesthetics of mobile phone shells are also getting higher and higher. [0003] At present, the use of gradient color effects for mobile phone shells has become the mainstream today. The more common preparation method for gradient color shells is to spray the gradient color on the front of the plate after silk screen printing logos and texture transfers on the back of the plate, and then perform optical coating on the back of the plate. And the background color of silk screen printing, and finally carry out high-pressure or hot-bending molding. ...

[0003] At present, the use of gradient color effects for mobile phone shells has become the mainstream today. The more common preparation method for gradient color shells is to spray the gradient color on the front of the plate after silk screen printing logos and texture transfers on the back of the plate, and then perform optical coating on the back of the plate. And the background color of silk screen printing, and finally carry out high-pressure or hot-bending molding. Although this production process can produce the required gradient color, in the process of high-pressure or hot-bending molding, the paint surface of the board is prone to cracking and falling off.
