Abstract

The invention discloses a production process of a 3D glass back cover plate of a mobile phone, comprising the steps of: cutting a 3D glass raw material by using a glass substrate cutting machine to obtain a base material; performing CNC processing on the base material, then putting the processed base material into a graphite mold, and then conducting shaping with hot pressing and bending in a hotpressing bending machine, and conducting cooling to obtain a slab; polishing the slab, and then conducting tempering to obtain a tempered slab; and conducting LOGO screen printing and spraying ink onthe tempered slab, and conducting drying, so as to obtain the 3D glass back cover plate of the mobile phone. The production process of the 3D glass back cover plate of the mobile phone provided by theinvention has a simple process and a low defect rate, the obtained back cover plate has a high strength, and good wear resistance and heat resistance.

Description

technical field [0001] The invention relates to the technical field of mobile phones, in particular to a production process for a 3D glass rear cover of a mobile phone. Background technique [0002] 3D glass has the advantages of light and thin, transparent and clean, anti-fingerprint, anti-glare, and good weather resistance. It has been used in the production and manufacture of mobile phone back covers. The finished mobile phone cover has a better grip and aesthetic feeling, and is more ergonomic. Although the production and processing technology of the 3D glass mobile phone back cover has become increasingly mature, there are still some problems in the production process of the 3D glass back cover, such as the high rate of poor polishing, and the strength, wear resistance and durability of the produced back cover. The heat is not very ideal, etc., which limits its development. Contents of the invention [0003] Based on the technical problems existing in the background...
