Embodiment Construction

[0015] The casing 100 of the preferred embodiment of the present invention is as figure 1 As shown, it includes a film layer 14 , a decoration layer 12 disposed on the film layer 14 and a base layer 10 combined on the decoration layer 12 .

[0016] The film layer 14 is a plastic layer, which can be made by injection molding. The material forming the film layer 14 can be selected from any one of polycarbonate (PC), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA) or polylactic acid (PLA). . The thin film layer 14 includes an outer surface 141 and an inner surface 143 opposite to the outer surface 141, and the outer surface 141 is formed with several geometric three-dimensional patterns, such as circular, square or other irregularly shaped grooves, Protrusions or other textures, the three-dimensional pattern on the outer surface 141 in this embodiment is a square groove. The inner surface 143 is flat.

[0017] The decoration layer 12 can be an ink layer, whic...

Abstract

The invention relates to a shell, which comprises a transparent thin-film layer, a decorative layer arranged on the transparent thin-film layer and a substrate layer combined with the decorative layer, wherein the thin-film layer comprises an external surface and an internal surface opposite to the external surface; the decorative layer is arranged on the internal surface of the thin-film layer; and the external surface of the thin-film layer is provided with a plurality of three-dimension patterns in geometrical shapes. The manufacturing method of the shell comprises the following steps: providing the transparent thin-film layer; providing two rolling wheels rotating relatively and keeping a slit between the two rolling wheels, wherein the surface of at least one rolling wheel is provided with the plurality of three-dimension patterns in the geometrical shapes; allowing the two rolling wheels to rotate relatively and vertically inserting the thin-film layer through the slit between the two rolling wheels to form the three-dimension geometrical patterns on one surface of the thin-film layer by the rolling of the rolling wheel; arranging the decorative layer on the surface, without rolled geometrical patterns, of the thin-film layer; and combining the substrate layer with the decorative layer.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a three-dimensional effect on the surface and a manufacturing method thereof. Background technique [0002] Most of the casings of existing portable electronic products are made by IML (in-mold film injection molding) technology. 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 shell made by this process is a wear-resistant and scratch-resistant transparent film, the middle is a printing ink layer, the inner surface is a plastic layer, and the printing ink is sandwiched in the middle, which can prevent falling off and being worn during use, so It can maintain the bright and bright color of the product for a long time, and is favored by consumers. In order to obtain a mor...
