Method of preparing electronic device case

Abstract

The invention provides a manufacturing method of the casing body of an electronic device. The casing body of the electronic device comprises a thin film layer and a matrix, wherein, the thin film layer forms the outer layer of the casing body of the electronic device, figures are formed on the outer layer, the manufacturing material thereof adopts plastics, glass, ceramics, and the like, the matrix forms the main component part of the casing body of the electronic device, the manufacturing material thereof adopts resin, and the matrix is integrally molded with the thin film layer to form the casing body of the electronic device. The main method comprises the following steps: the thin film layer is placed in the mould cavity of the die firstly, then the plastic or the resin is cast and fully combined with the thin film layer, the formed casing body is taken out, patterns are printed on the thin film layer of the casing body to from the casing body of the electronic device with figures. The figures are printed on the thin film layer of the casing body after the casing body is molded, the method is novel, and the quality of the patterns is ensured.

Description

technical field [0001] The invention relates to a manufacturing method of an electronic device casing, in particular to an electronic device casing with graphics and a manufacturing method thereof. Background technique [0002] With the development of mobile communication technology, various electronic devices such as mobile phones are emerging, so that consumers can fully enjoy the convenience brought by mobile technology anytime and anywhere. More and more people's attention and attention. [0003] The forming process of the shell of traditional electronic devices is generally as follows: after the shell is formed, it is then painted, and then the surface of the shell after baking is printed to form a pattern on the surface of the shell. This manufacturing process needs to be painted, and then print graphics on the surface of the shell. The manufacturing process is relatively cumbersome, and the graphic printing effect on the shell is closely related to the baking process...

Problems solved by technology

However, this technology also has certain defects. Since the graphics are printed on the film before forming, considering that the graphics are composed of some ink particles, during the forming process, the ink particles are subject to higher mold pressure. Diffusion or volatilization occurs due to high temperature, resulting in edge staining on the graphics on the molded shell, which affects the aesthetics of the graphics
