Problems solved by technology

[0003] However, the wear resistance of the surface formed by spraying and baking varnish is poor, the surface is extremely easy to wear and the sprayed varnish is easy to peel off, thereby affecting the appearance of the product, which cannot meet the requirements of consumers for the appearance of the product, and the surface formed by this method Very smooth, easy to slip and cause damage to the product
If you want to make the surface of the metal shell have patterns, etc. by spraying baking paint, it will make the processing more complicated

Embodiment Construction

[0017] The present invention provides a metal casing, and a preferred embodiment of the metal casing is applied to a mobile phone.

[0018] The surface of the metal shell has the appearance of a knurling pattern, and the knurling pattern can be milled twice in two diagonal directions on the surface of the workpiece through diamond engraving technology, so as to form the appearance of a knurling pattern composed of several rhombuses. The material of the metal shell can be any one or combination of copper, iron, aluminum, stainless steel and titanium, and the material of the metal shell in the preferred embodiment of the present invention is aluminum alloy.

[0019] Please refer to FIG. 1 and FIG. 2 for the manufacturing process and manufacturing method of the metal shell with a knurled surface, which specifically includes the following steps:

[0020] Stamping the metal sheet, the process is to punch the metal sheet through a stamping machine, stretch the edge, and then cut off...

Abstract

The invention provides a metal shell and a manufacture method thereof. A rolling pattern is formed on the surface of the metal shell. The method for manufacturing the metal shell comprises the following steps: forming the metal shell after punching a sheet metal; proceeding grinding and polishing treatments on the surface of the metal shell; applying a diamond engraving technology on the surface of the metal shell to form the rolling pattern. Processed by the manufacturing method, the surface of the metal shell is formed with the rolling pattern thus resulting in a beautiful appearance of a product and having an anti-slip function. The method for manufacturing the metal shell has the advantages of simple processing and convenient operating.

Description

technical field [0001] The present invention relates to a metal casing and a manufacturing method thereof, in particular to a metal casing applied to a portable electronic device and a manufacturing method thereof. Background technique [0002] With the rapid development of information technology, the application of portable electronic devices such as mobile phones, PDA (Personal Digital Assistant, personal digital assistant) and notebook computers is becoming more and more common. with attention. At present, metal shells are widely used in these portable electronic devices. The shells of the devices have high requirements on appearance. In the prior art, in order to improve the appearance of the metal shell surface, methods such as surface spraying and baking paint are generally used for decoration to enhance its appearance. beauty. [0003] However, the wear resistance of the surface formed by spraying and baking varnish is poor, the surface is extremely easy to wear and...
