Problems solved by technology

[0003] However, the wear resistance of the surface formed by spraying and baking paint is poor, and the sprayed paint is easy to wear and peel off, which affects the appearance of the product and cannot meet the requirements of consumers for the appearance of the product.
In addition, if you want to make the surface of the metal shell have patterns, etc. by spraying baking paint, the processing procedure will be more complicated.

Embodiment Construction

[0017] see figure 1 and figure 2 , the metal casing 10 of the preferred embodiment of the present invention, which can be applied to portable electronic devices, such as mobile phones.

[0018] The metal shell 10 includes a surface 12 on which a plurality of first textures 122 arranged at intervals and a plurality of second textures 124 arranged at intervals are formed. The plurality of first textures 122 have the same curvature, and the second textures 124 have the same curvature. The first textures 122 and the second textures 124 are anti-staggered. The so-called reverse interlacing means that there is an intersection between the first lines 122 and the second lines 124, and the extension direction of the first lines 122 and the extension direction of the second lines 124 are symmetrical with respect to a straight line passing through the intersection. , and the straight line is located on the plane formed by the extending directions of the first texture 122 and the seco...

Abstract

The invention provides a metal shell and a manufacturing method thereof. The surface of the metal shell is provided with a plurality of first lines which are arranged at intervals and have the same curvature and a plurality of second lines which are arranged at intervals and have the same curvature; the first lines are respectively crossed with the second lines to from a plurality of rectangular pyramid or rectangular platform protrusions. The first lines and the second lines are all grooves with V-shaped sections, and the first lines and the second lines are conversely crossed. The depth of the first lines and the second lines is 0.28mm, and the opening angle of the first lines and the second lines is 140 degrees.

Description

technical field [0001] The present invention relates to a metal casing and a manufacturing method thereof, in particular to a metal casing used in portable electronic devices and a manufacturing method thereof. Background technique [0002] With the rapid development of information technology, portable electronic devices such as mobile phones, PDA (Pe to personal Digital Assistant, personal digital assistant) and notebook computers are increasingly popular, and the aesthetics and feel of these electronic device casings are becoming more and more popular. attention and attention. At present, metal casings are widely used in these portable electronic devices. The casings of the devices have high requirements on appearance and wear resistance. Enhance the beauty of its appearance. [0003] However, the wear resistance of the surface formed by spraying and baking varnish is relatively poor, and the sprayed paint is very easy to wear and peel off, which affects the appearance o...
