Embodiment Construction

[0030] see figure 1 , which discloses a portable electronic device 10 according to an embodiment of the present invention. The electronic device 10 may be a digital photo frame, an e-book reader, or an MP3 player. The electronic device 10 includes a casing 11 and a display area 13 .

[0031] Please also refer to figure 2 , the housing 11 includes a plastic substrate layer 110 and a pattern layer 12 formed on the plastic substrate layer 110 . In the first embodiment, the pattern layer 12 sequentially includes an adhesive layer 111 , a metal coating layer 112 and a transparent protection layer 113 .

[0032] In this embodiment, the transparent protective layer 113 is a layer of transparent plastic film with a thickness between 0.1 mm and 0.5 mm. The material of the transparent protective layer 113 may be polyethylene terephthalate, polycarbonate or polymethyl methacrylate.

[0033] The metal coating layer 112 is sputter deposited on one surface of the transparent protectiv...

Abstract

A shell comprises a plastic base material layer. The shell also comprises a transparent protection layer which adheres on an outer surface of the plastic base material layer. A metal coating layer which is deposited through sputtering on the transparent protection layer is arranged between the transparent protection layer and the plastic base material layer. The metal coating layer is directly deposited through the sputtering on a transparent film and then adheres on the plastic base material layer. By using the method of the invention, a printing ink shrinkage phenomenon generated by a printing ink protection layer coated after directly using a PVD method to deposit the metal coating layer on the plastic base material layer can be avoided.

Description

technical field [0001] The invention relates to a casing, in particular to a casing applied to a portable electronic device and a manufacturing method thereof. Background technique [0002] In order to make the portable electronic device have a better appearance and special visual perception, some decorative textures, patterns and trademarks are usually formed on the casing of the portable electronic device. [0003] In-mold labeling technology (IML, IN MOLDING LABEL) is a film with a printed pattern placed in the injection mold. After the injection molding is completed, the film and the plastic are tightly integrated through the action of the adhesive, so that it can be used in portable electronic devices. A method of forming a pattern on the casing. The traditional IML process sequentially includes: material cutting, flat printing, ink drying, positioning punching, thermoforming, cutting, material injection molding and other steps. In the IML process, the film is general...
