Abstract

The invention relates to the technical field of mobile phone rear covers, in particular to a 3D printing production process of a gradient-color mobile phone rear cover. The process comprises the following steps of (1) cutting; (2) LOGO printing; (3) varnish printing; (4) 3D printing; (5) electroplating; (6) cover bottom printing; (7) high-pressure treatment, specifically, a substrate is arranged on a high-pressure forming machine to be subjected to high-pressure forming, and an arc side is formed; (8) reinforcement, specifically, hardening liquid is sprayed on the substrate to be curved to form a hardened film; and (9) CNC cutting, specifically, the substrate is subjected to numerical control cutting, and the gradient-color mobile phone rear cover is obtained. The gradient-color process isachieved through 3D digital printing, a product printed by 3D digital printing is colored evenly, the gradient effect is good, a plurality of color gradients can be printed, the production cost is low, the efficiency is high, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of mobile phone back covers, in particular to a 3D printing production process for gradient color mobile phone back covers. Background technique [0002] Today, as the mobile phone market is expanding, the competition in the processing of mobile phone back covers is also intensifying. Major mobile phone companies continue to develop new processes, hoping to use new processes to reduce production costs and improve the company's market competitiveness. Gradient color effect is a kind of appearance effect that is more popular in the market. The existing production process mostly adopts the method of printing semi-transparent color to produce gradient color products, but the printed products will have obvious color layering, and the gradient effect is poor. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to prov...
