Embodiment Construction

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

[0014] A transparent film layer is provided. The transparent film layer is made of transparent plastic, which can be selected from polypropylene (PP), polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET) and polymethyl Either of methyl acrylate (PMMA). The thickness of the transparent film layer is about 0.125-0.175mm.

[0015] A decoration layer is printed on one surface of the transparent film layer. The decorative layer can be a colored transparent or translucent ink layer, which can be formed by conventional screen printing. The thickness of the decoration layer is between 3.5-4.5 μm.

[0016] A non-conductive metal layer is arranged on the surface of the decoration layer. The non-conductive metal layer can be made by vacuum evaporation or sputtering. The target material for evaporating or sputtering the non-conductive metal...

Abstract

The invention provides a manufacturing method of a shell and a shell obtained by the same. The manufacturing method of the shell comprises the following steps of: providing a transparent film layer; arranging a non-conducting metal layer on one surface of the transparent film layer; arranging a protective layer on the non-conducting metal layer; and molding a substrate on the protective layer by injection. The shell comprises the film layer, the substrate, the non-conducting metal layer formed on the surface of the transparent film layer and the protective layer formed on the surface of the non-conducting metal layer, and the substrate is combined with the protective layer in the manner of injection molding.

Description

technical field [0001] The invention relates to a manufacturing method of a shell and a shell made by the method, in particular to a manufacturing method of a shell with a metal appearance and the shell made by the method. Background technique [0002] The IML process is currently widely used in the manufacture of casings for portable electronic products. The casing made by this process usually includes a transparent plastic film, an ink layer printed on the inner surface of the plastic film and a plastic matrix layer injected on the surface of the ink layer. The outer surface of the casing made by this process is a wear-resistant and scratch-resistant transparent film, the middle is a printing ink layer, and the inner surface is a plastic layer. The printing ink is sandwiched in the middle, which can prevent the ink from falling off and being damaged during use. Wear and tear, so it can maintain the bright and bright color of the product for a long time, which is favored b...
