Embodiment Construction

[0016] The casing 100 of the preferred embodiment of the present invention is as figure 1 As shown, it includes a first film layer 16, a leather paint layer 18 and a second film layer 14 bonded to the opposite surface of the first film layer 16, a decorative layer 12 formed on the surface of the second film layer 14 and a The base layer 10 combined on the decoration layer 12 .

[0017] The first film layer 16 is a transparent plastic layer, and the plastic can be selected from any one of polypropylene (PP) or polyamide (PA). The first film layer 16 includes an outer surface 161 and an inner surface 163 opposite to the outer surface 161 .

[0018] The leather paint layer 18 is a polyurethane varnish layer, which can be formed on the outer surface 161 of the first film layer 16 by coating.

[0019] The second film layer 14 is a transparent plastic layer bonded to the inner surface 163 of the first film layer 16 . The material forming the second film layer 14 can be selected f...

Abstract

The invention relates to a shell, which comprises a thin film layer, a decorative layer formed on the thin film layer and a substrate layer combined with the decorative layer. A leather dope layer is formed on the surface of the thin film layer. The manufacturing method for the shell comprises the following steps: manufacturing a first thin film layer; coating the leather dope layer on the surface of the first thin film layer; providing a second thin film layer; providing two pairs of rollers which relatively rotate; forming a slit between the two rollers; making the two rollers relatively rotate; attaching the first thin film layer coated with the leather dope layer and the second thin film layer; making the attached layer vertically pass through the slit between the two rollers; crushing the two thin film layers into a whole body; arranging the decorative layer on the surface of the second thin film layer; and combining the substrate layer on the decorative layer.

Description

technical field [0001] The present invention relates to a casing and a manufacturing method thereof, in particular to a soft-touch casing and a manufacturing method thereof. Background technique [0002] The shells of existing portable electronic products are mostly made by IML (in-mold film injection molding) process. 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 layer 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 layer is a plastic layer. The printing ink layer is sandwiched in the middle, which can prevent the ink layer from falling off and Being worn, it can maintain the bright and bright color of the product for a long time, which is favored by consumers. However, although the film surface of the casin...
