Electronic product curved surface shell manufacturing method

Abstract

The invention belongs to the technical field of electronic equipment, and provides an electronic product hook face shell manufacturing method. The electronic product hook face shell manufacturing method is characterized in that an electronic product hook face shell is made of acrylic materials; and the method comprises the following steps that firstly, a semi-finished product is machined and formed; secondly, surface PVD coating treatment is conducted on the semi-finished product obtained in the first step; thirdly, surface hardening treatment is conducted on the semi-finished product obtainedin the second step; and fourthly, surface ink transfer printing treatment is conducted on the semi-finished product obtained in the third step. According to the electronic product hook face shell manufacturing method, the ink transfer printing scheme is adopted in the ink technology, cleanliness is achieved, pollution is little, and cost is low; and a surface hardening layer generated after surface hardening treatment can cover the hook face edge position of a PVD film generated after PVD coating treatment, the situation that the PVD film is cracked from the hook face edge to the middle in the ink transfer printing technology can be avoided, and the production quality of the PVD film is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a method for manufacturing a curved shell of an electronic product. Background technique [0002] At present, there are two schemes for the ink process of the shell of 3D electronic products: one is pad printing; the other is spraying. [0003] Pad printing is to directly transfer the pattern of the rubber head to the shell of the electronic product, and spray the ink directly to the surface of the shell of the electronic product through air pressure atomization and make a pattern with the help of a jig. In the manufacturing process of existing electronic product casings, the process of: shape processing → surface hardening → PVD vacuum film → spraying ink or shape processing → surface hardening → PVD vacuum film → pad printing ink, compared with spraying, pad printing It has obvious advantages: clean, less pollution, easy operation, good effect, substan...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a method for manufacturing a curved shell of an electronic product. The ink process adopts the scheme of pad printing ink, which is clean, less polluted, and low in cost, and the surface produced after surface hardening treatment The hardened layer can cover the edge of the curved surface of the PVD film layer formed after PVD coating treatment, which can prevent the PVD film layer from cracking from the edge of the curved surface to the middle during the pad printing ink process
