Embodiment Construction

[0017] The manufacturing method of the shell of the present invention is used for making the shell with two or more colors, color gradient effect and soft hand feeling. The following is an example of making a shell with two color gradient effects and soft touch.

[0018] see figure 1 and image 3 , the housing 10 of the preferred embodiment of the present invention (such as image 3 Shown) the preparation method comprises the following steps:

[0019] Step S1 : providing a plastic base 11 . The plastic base body 11 can be injection molded, which has the structure of the housing to be produced. The plastic forming the plastic matrix 11 may be selected from polyethylene (PE), polyamide (PA), polycarbonate (PC), acrylonitrile styrene butadiene copolymer (ABS), polymethyl methacrylate (PMMA ) and polyethylene terephthalate (PET) and other plastics or a combination of several.

[0020] Step S2: forming (eg, spraying) a primer layer 12 on the surface of the plastic substrate 1...

Abstract

The invention provides a making method of a shell, comprising the following steps of supplying a plastic substrate; forming a priming paint layer on the surface of the plastic substrate; forming a vacuum film plating layer with the metal appearance on the priming paint layer; forming a transparent or semi-transparent first colored paint layer on the vacuum film plating layer; forming a transparent or semi-transparent second colored paint layer on the surface of the first colored paint layer, wherein the second colored paint layer comprises a shielding region and a transition region which is connected with the shielding region, and the density of paints is gradually reduced from the position of the transition region neighboring the shielding region to a common boundary of the transition region and the first colored paint layer; and forming a transparent finish paint layer on the surface of the second colored paint layer and the surface of the first colored paint layer without coating with the second colored paint layer. The invention also provides the shell fabricated through the method. The shell has the effect of gradual change of colors.

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 color gradient effect and the shell made by the method. Background technique [0002] The IML process is currently widely used in the manufacture of portable electronic product casings. The casing made by this process usually includes a transparent, wear-resistant and scratch-resistant plastic film on the outer surface of the casing, an ink layer printed on the inner surface of the plastic film, and a plastic substrate injected on the inner surface of the ink layer layer. The printing ink layer is sandwiched between the plastic film and the plastic substrate layer, which can prevent the ink from falling off and being worn out during use, so it can maintain the bright and bright color of the product for a long time, which is favored by consumers. However, the printing ink layer usually can only present a ...
