Problems solved by technology

[0004] However, the above-mentioned processing methods all process gaps on the shell first, and then carry out bottom injection reinforcement
Because the thickness of the shell is relatively thin, the strength of the matrix becomes worse after the gap is processed in this way, and the shell is easily deformed during re-injection molding.

preparation example Construction

[0044] The present invention also provides a method for preparing a metal casing of a communication device, wherein the method includes the following steps:

[0045] 1) injecting resin on at least a part of the inner surface of the metal substrate to form a plastic support layer;

[0046]2) More than one slit is formed in the area of ​​the metal substrate where the plastic support layer is formed, and the slit penetrates the metal substrate and does not penetrate the plastic support layer.

[0047] According to the present invention, the thickness of the metal substrate and the thickness of the plastic supporting layer are not particularly limited, and those skilled in the art can make appropriate selections according to specific communication devices. For example, the thickness of the metal substrate may be 0.1-0.6 mm, preferably 0.2-0.5 mm; the thickness of the plastic support layer may be 1-2 mm, preferably 1.2-1.8 mm.

[0048] According to the invention, the resin is pref...

[0069] 1) Injection molding on one surface of the metal substrate

[0070] An aluminum alloy (purchased from Dongguan Gangxiang Metal Materials Co., Ltd., grade 6063, thickness 0.6 mm) was cut into a size of 15 mm x 80 mm as a metal substrate. Degreasing and washing with water were performed on the above metal substrate to remove surface stains and oil stains, and then dried at 80°C for 20 minutes to obtain the cleaned and dried metal substrate A11.

[0071] Put the above metal substrate A11 into a mold, and use polyphenylene sulfide resin to inject the inner surface of the metal substrate A11. Injection molding conditions are: mold temperature 280°C, nozzle temperature 400°C, holding time 30s, injection pressure 260MPa, injection time 20s, delay time 20s, cooling time 40s, forming a plastic support layer (thickness 2.0mm), so as to obtain Metal housing A12 with injection molded support layer.

Abstract

The invention discloses a communication equipment metal shell and a preparation method thereof. The communication equipment metal shell comprises a metal substrate, slits and a plastic support layer, wherein the plastic support layer covers at least one part of the inner surface of the metal substrate; the slits run through the metal substrate and do not run through the plastic support layer; and the section shapes of the parts, located on the plastic support layer, of the slits are one or more of an inverted cone, an arc shape, a rectangle and an inverted trapezoid. The slits of the communication equipment metal shell disclosed by the invention do not deform and the communication equipment metal shell has smooth consistency in appearance.

Description

technical field [0001] The invention relates to a metal shell of communication equipment and a preparation method thereof. Background technique [0002] For mobile phones, tablet computers, notebook computers and other similar portable electronic communication devices, compared with plastic casings, metal casings are more beautiful, more textured, and have superior performance such as wear resistance and scratch resistance. Therefore, whether it is from the manufacturer Or from the user's point of view, the use of metal casings in large areas has become a future development trend. However, in the prior art, since electromagnetic waves cannot penetrate metals, electronic communication equipment can only be designed with non-metallic casings, or when metal casings are used, non-metallic materials must be used for partitioning at the antenna. [0003] In the prior art, in order to ensure the normal communication of the communication equipment under the premise of using the met...
