Problems solved by technology

Although the method of direct injection molding the shell is simple, it also has its own shortcomings, such as the injection molding plastic layer is difficult to thin; and the plastic is in a high temperature state during pouring, and the volume of the plastic shrinks when it is cooled and molded, so it is difficult to accurately Control the size of the formed product
However, with the IML process, on the one hand, it is still difficult to accurately control the size of the product when injecting the base layer, and the thickness of the product is difficult to thin. On the other hand, the IML process itself has many procedures, high cost, and a high probability of defective products.

Embodiment Construction

[0007] The portable electronic device casing 100 of the preferred embodiment of the present invention is as figure 1 As shown, it includes a first film layer 10 and a second film layer 12 bonded to the surface of the first film layer 10 .

[0008] The first film layer 10 is a transparent plastic layer, and the plastic can be selected from any one of polypropylene (PP) or polyamide (PA). The first film layer 10 includes an outer surface 101 and an inner surface 103 opposite to the outer surface 101 . The thickness of the first film layer 10 can be between 0.15mm and 0.2mm.

[0009] The second film layer 12 is a transparent plastic layer bonded to the inner surface 103 of the first film layer 10 . The material forming the second film layer 12 can be selected from any one of polycarbonate (PC), polyethylene terephthalate (PET) or polymethyl methacrylate (PMMA). The first film layer 10 and the second film layer 12 can be combined together by rolling with two rollers. The thick...

Abstract

The invention relates to a portable electronic device shell made by forming a plastic film layer in a thermal pressing forming mode. The portable electronic device shell has small thickness and satisfies the requirement of thin products, and the manufacture method thereof is simple and practical and has few working procedures and low cost.

Description

technical field [0001] The present invention relates to a casing, in particular to a casing of a portable electronic device. Background technique [0002] At present, the casings of portable electronic products such as mobile phones are all developing towards thinning, so as to make the products smaller in size and lighter in weight. Existing methods for making casings of portable electronic products usually include direct injection molding of plastics in molds or the use of IML (Injection Molding Molding) technology. Although the method of direct injection molding the shell is simple, it also has its own shortcomings, such as the injection molding plastic layer is difficult to thin; and the plastic is in a high temperature state during pouring, and the volume of the plastic shrinks when it is cooled and molded, so it is difficult to accurately Control the size of the formed product. However, with the IML process, on the one hand, it is still difficult to accurately contro...
