Description

Plastic mobile phone rear cover

Technical Field

The utility model relates to a lid system field behind the plastics cell-phone, concretely relates to lid behind plastics cell-phone.

Background

At present, a plurality of problems exist in the process of manufacturing a plastic mobile phone rear cover by adopting optical-grade transparent plastics, for example, in the conventional method, the optical-grade transparent plastics are subjected to injection molding and then hardened, and then the explosion-proof film subjected to texture transfer printing, film coating and silk printing is attached to obtain the plastic electronic product rear shell with the three-dimensional background pattern. Meanwhile, when the high-reflectivity coating penetrates through the adhesive layer, appearance defects are amplified. Furthermore, the separation performance is poor when a plastic mold is used for UV transfer printing, and a release layer, such as a fluorine coating layer or a metal layer that reduces surface tension, is generally plated, but as the number of uses increases, the coating layer or the metal layer is gradually damaged, resulting in failure of the mold. Moreover, the edge of the rear cover of the plastic mobile phone is not protected, so that the plastic mobile phone is easy to lose in the installation process.
