Production process and molding equipment for 3D (three-dimensional) battery cover

Abstract

The invention discloses a production process for a 3D (three-dimensional) battery cover. The production process is realized by the following steps: compounding a PMMA (Polymethyl Methacrylate) film with a PC (Polycarbonate) thin film to form a compound board; sequentially arranging a LOGO pattern printing layer, a UV(ultraviolet) transfer printing texture pattern layer, an optical film layer and abase color ink layer on the bottom surface of the PC thin film from top to bottom to form a to-be-molded sheet; putting the to-be-molded sheet on molding equipment for molding at high pressure to obtain a molded semi-finished product; carrying out shower coating of UV hardening liquid on the top of the surface of the molded semi-finished product by using a pressure gun; enabling the surface of the molded semi-finished product to be coated with the UV hardening liquid fully, and then drying to form a surface treatment part; cutting on the surface treatment part by reverse placement by using aCNC (Computer Numerical Control) cutter to form a finished product of the 3D battery cover. Compared with the prior art, the 3D battery cover has the advantages that the battery cover also has good toughness and higher hardness on the premise of reaching excellent strength as well as high rate of the molded finished product and highlight effect of the surface. The invention also discloses moldingequipment for the 3D battery cover.

Description

Technical field [0001] The invention relates to the field of manufacturing of mobile phone accessories, in particular to a manufacturing process of a 3D battery cover and a molding device used for 3D battery cover molding. Background technique [0002] Most of the battery covers of various communication electronics and household appliances on the market are made of plastic materials. At the same time, in order to prevent the surface pattern from being scratched, the pattern layer is generally set on the back of the battery cover, so that the pattern can keep the color vivid for a long time. Fading, this is also what the society wants. In order to enhance the appearance effect of the battery cover, UV varnish is usually used for repeated overlay printing to achieve the purpose of presenting a three-dimensional pattern effect. However, the battery cover made of this plastic material has a slightly lower hardness and cannot show a bright effect. At the same time, the traditional pl...
