Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] Such as figure 1 As shown, the embodiment of the present invention provides a method for preparing a battery back cover, including: forming a transparent shell body with a hyperboloid structure through plastic pellets through an injection molding process; A pattern layer: performing wear-resistant treatment on the exposed outer surface of the shell body to form a transparent wear-resistant layer.

[0020] Due to the reincarnation of mobile phone casing...

Abstract

The invention relates to the field of battery rear covers, and discloses a battery rear cover preparation method. The method comprises the following steps: carrying out an injection molding process onplastic particles to form a transparent shell body having a hyperboloid structure; forming a pattern layer on the inner surface, used for making contact with a battery, in the shell body; and carrying out a wear-resisting process on the exposed outer surface in the shell body to form a transparent wear-resisting layer. The problem that the plastic battery rear cover of an existing hyperboloid mobile phone does not have a glass-imitating effect can be solved.

Description

technical field [0001] The invention relates to the technical field of a battery back cover, in particular to a method for preparing a battery back cover. Background technique [0002] The materials of mobile phone casings have changed from plastic to metal and then to non-metallic materials, and plastic is favored by the low-end market because of its low cost. [0003] In the production of mobile phone battery back cover, there is no obvious difference in the product appearance effect achieved by the IMT injection molding process and the composite sheet, but the shape of the composite sheet is hot-pressed, and the product size is unstable, and the composite sheet can only be made into a sheet. The mobile phone battery back cover with a single curved surface has limitations in application scenarios; while the IMT injection molding process can make a hyperboloid integrated back cover with dazzling effects, but all effects are realized on the surface of the product, which lack...
