Abstract

The embodiment of the invention discloses a preparation method of a mobile phone rear shell and the mobile phone rear shell. The preparation method comprises the following steps: acquiring a base material which is made of a mixture of PC and PMMA and is in a transparent plate shape through raw material cutting treatment; enabling the base material to be in a multi-color or gradient color through offset printing or dip dyeing treatment; enabling the base material to have a certain color and achieve shading through bottom color printing and bottom covering treatment; and forming fillets on the edge of the base material through hot bending forming treatment. By means of the mode, the mobile phone rear shell with the texture close to that of glass or ceramic materials can be manufactured, andshielding and interference of the metal mobile phone rear shell on mobile phone signals are avoided.

Description

Technical field [0001] This application relates to the technical field of mobile phone back shells, and in particular to a method for preparing a mobile phone back shell and a mobile phone back shell. Background technique [0002] Nowadays, mobile phones have become an indispensable part of people's daily life. The different needs of consumers have also prompted major mobile phone manufacturers to innovate and create more mobile phones that can satisfy users' aesthetics and practicality. With the development of technology, the 5G era is getting closer and closer to us. One feature of 5G is millimeter wave. The shorter the wavelength, the higher the transmission frequency and the faster the transmission speed. [0003] At present, the back shell of a mobile phone is usually made of metal, and the metal back shell can shield and interfere with signals, limiting the transmission speed. Summary of the invention [0004] The embodiments of the present application provide a method for pr...
