Problems solved by technology

The outer coating can protect the metal layer to a certain extent, but the outer coating itself has the disadvantages of weak bonding with the metal layer, easy to fall off and easy to be worn, so it is still difficult to play a good role in protecting the metal layer. protective effect

Embodiment Construction

[0013] The manufacturing method of the casing of the preferred embodiment of the present invention comprises the following steps:

[0014] A transparent film is provided. The film can be made of plastic material, such as polyethylene terephthalate (PET) plastic or polycarbonate (PC) plastic. The film made of polyethylene terephthalate or polycarbonate has good abrasion resistance and high surface hardness.

[0015] A transparent or translucent decorative layer is formed on one surface of the transparent film. The decoration layer can be a transparent or translucent ink layer, which can be formed on the surface of the film by screen printing. The decorative layer can also be a transparent or translucent baking varnish layer, which can be formed on the surface of the film by means of paint spraying. The decorative layer can be colorless or colored.

[0016] A coating layer is plated on the decoration layer. The coating layer can be a coating layer with metal texture. The m...

Abstract

A manufacturing method of a casing is disclosed, and the method comprises the following steps: providing a transparent film; forming a transparent or translucent decorative layer on the film; plating a metallic filming layer on the decorative layer; combining a substrate layer on the filming layer. A casing manufactured by the method is also disclosed, and the method comprises a transparent film layer and a substrate layer, the film layer is provided with a transparent or translucent decorative layer, the decorative layer is provided with a metallic filming layer, the filming layer is provided with a protective layer, and the substrate layer is combined on the protective layer.

Description

technical field [0001] The invention relates to a manufacturing method of a shell and a shell made by the method. Background technique [0002] Existing plastic casings of portable electronic devices such as mobile phones and personal digital assistants are usually coated with a decorative layer to beautify the appearance of the product. For example, vacuum coating can be used to coat a metal layer on the surface of the casing, so that the surface of the casing has a metallic texture. However, the metal layer formed by the vacuum coating method generally has certain chemical activity, and the metal layer is easily oxidized when exposed to the air, and the metal layer is also easily scratched and worn during use, thus affecting the quality of the product. Exterior. In order to avoid oxidation, scratches and wear of the metal layer, people spray topcoat on the metal layer to form an outer coating. The outer coating can protect the metal layer to a certain extent, but the ou...
