Problems solved by technology

However, the appearance of the above casing can only show the color and appearance of the printing ink, and it is difficult to have a metallic texture
Moreover, the surface of the plastic film is relatively smooth, and the hand feel is relatively simple.

Embodiment Construction

[0015] The housing 10 of a preferred embodiment of the present invention (such as figure 1 Shown) the preparation method comprises the following steps:

[0016] A transparent plastic film 11 is provided. The material of the plastic film 11 can be selected from polypropylene (PP), polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET) and polymethyl methacrylate (PMMA) any of the.

[0017] On one surface of the plastic film 11, a leather varnish layer 12 having a soft touch is formed (eg, coated).

[0018] A decorative layer 13 is formed (such as printed) on the surface of the plastic film 11 opposite to the leather paint layer 12 . The decoration layer 13 can be transparent or a colored ink layer with a certain degree of transparency, which can be formed by conventional screen printing.

[0019] A non-conductive metal layer 14 is formed on the surface of the decoration layer 13 . The non-conductive metal layer 14 can be made by vacuum evaporation or sputteri...

Abstract

The invention provides a production method of a shell, comprising the following steps of: providing a transparent plastic film; forming a leather paint layer with soft feel on one surface of the plastic film; forming a decorative layer on the surface of the plastic film opposite to the leather paint layer; forming a nonconductive metal layer on the surface of the decorative layer; setting a protective layer on the nonconductive metal layer; and carrying injection molding to form a basal body on the protective layer so as to form the shell. The invention also provides a shell prepared by the method. The shell has metal texture and soft feel.

Description

technical field [0001] The invention relates to a manufacturing method of a casing and a casing made by the method, in particular to a manufacturing method of a casing having both a metal appearance and a soft feel and the casing 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 matrix injected on the inner surface of the ink layer Floor. 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 appearance of the above cas...
