Problems solved by technology

However, the existing technology restricts the development of this trend. Because metal has electromagnetic shielding effect, many manufacturers still choose plastic casings as electronic communication equipment casings, and some manufacturers use plastic strips to separate metal technology to avoid shielding electromagnetic signals.
[0003] Although the technology of using plastic strips to separate metal can avoid shielding electromagnetic signals, the entire shell is divided into several pieces from the outside light, and there is no appearance integration effect

preparation example Construction

[0040] The invention provides a method for preparing a metal casing of a communication device, wherein the method includes the following steps,

[0041] 1) Provide a metal substrate, the metal substrate is provided with more than one slit;

[0042] 2) Paste reinforcing ribs in the area where slits are opened on the outer surface of the metal substrate;

[0043] 3) inject molding at least a part of the inner surface of the metal substrate;

[0044] 4) Removing the ribs from the metal substrate.

[0045] In the present invention, the region where the slit is opened on the outer surface of the metal substrate refers to the region on the metal substrate corresponding to the antenna of the communication device.

[0046] In the present invention, the thickness of the metal substrate is not particularly limited, and those skilled in the art can properly select it according to the specific communication equipment. For example, the thickness of the metal substrate may be 0.1-0.8 mm,...

Embodiment 1

[0079] 1) Form a slit

[0080] Aluminum alloy (purchased from Dongguan Gangxiang Metal Materials Co., Ltd., grade 6061, thickness 0.4mm) was cut into a size of 15mmx80mm as the metal substrate. Adopt laser machine (the model that Everbright Laser Technology Co., Ltd. produces is FM20D laser machine) to carry out slit processing (wherein, slit is 9, and shape is straight line) on metal substrate, and described slit width is 20 μ m, The length of the slit is 30 mm, and the distance between adjacent slits is 1 mm. The laser processing power is 50W, the speed is 50mm / s, the frequency is 20kHz, and the wavelength is 1064nm, and a metal substrate A11 with slits is obtained.

[0081] 2) Injection molding

Abstract

The invention discloses a communication equipment metal shell and a preparation method thereof. The communication equipment metal shell disclosed by the invention comprises a metal substrate, more than one slit and a plastic support layer, wherein the more than one slit runs through the metal substrate; and the plastic support layer covers at least one part of the inner surface of the metal substrate and fully fills the slits. The communication equipment metal shell which is suitable for various antennas and has an integrated effect in appearance can be provided.

Description

technical field [0001] The invention relates to a metal shell of communication equipment and a preparation method thereof. Background technique [0002] For various portable electronic communication devices such as mobile phones, notebook computers, and tablet computers, the use of metal casings has a more beautiful appearance and better texture than plastic casings, and has better wear resistance and compression resistance. Therefore, the use of metal casings As the shell of electronic communication equipment, it will become a trend in the future. However, the existing technology restricts the development of this trend. Because metal has electromagnetic shielding effect, many manufacturers still choose plastic casings as electronic communication equipment casings, and some manufacturers use plastic strips to separate metal technology to avoid shielding electromagnetic signals. [0003] Although the technology of using plastic strips to separate metal can avoid shielding el...
