Embodiment Construction

[0017] see figure 1 and figure 2 , a preferred embodiment of the manufacturing method of the metal shell of the present invention comprises the following steps:

[0018] Step S1: Provide a plastic base 10, which can be formed by injection molding, and the plastic base 10 has the structure of the shell to be manufactured.

[0019] Step S2: providing a decorative film 20 . The material of this decorative film 20 can be plastic, also can be leather, fabric etc., wherein plastic can be selected from polymethyl methacrylate (Polymethyl Methacrylate, PMMA), polyvinyl chloride (Polyvinly Chloride, PVC), polyethylene terephthalic acid One or a combination of vinyl ester (Polyethylene Terephthalate, PET), polycarbonate (Polycarbonate, PC), polyethylene (Polyethylene, PE), etc.

[0020] Step S3: Form a non-conductive coating layer 30 with metallic texture on the surface of the decorative film 20 by vacuum evaporation or sputtering. The material forming the non-conductive coating la...

Abstract

The invention provides a manufacturing method of a metalline shell, comprising the following steps: providing a plastic matrix with the pre-manufactured shell structure; providing a decorative film; forming a metalline non-conducting coated layer on the surface of the decorative film; ensuring the decorative film covered by the non-conducting coated layer to form a predetermined shape; cutting the decorative film with the predetermined shape to ensure the contour of the decorative film to form the periphery shape fitting the plastic matrix; and sticking the cut decorative film to the surface of the plastic matrix. The invention also provides the shell manufactured by the method.

Description

technical field [0001] The invention relates to a manufacturing method of a shell with metal texture and the shell made by the method. Background technique [0002] Due to the characteristics of easy molding and light weight, plastics are widely used in the manufacture of electronic product appearance parts. As the electronic product market has higher and higher requirements on product appearance, people are no longer satisfied with the color of plastic itself, and electronic products with metallic luster have become the new favorite of the market. [0003] In order to obtain a metallic luster on the surface of the plastic housing of an electronic product without affecting the appearance of the radio frequency, an existing method is to form a film with a metallic luster on the surface of the plastic molding by a non-conductive vacuum coating process (NCVM). Then perform other decorative treatments on the surface of the film with metallic luster as required, such as spraying...
