Example Embodiment

[0019] Please refer to FIG. 1 and FIG. 2, the metal casing 10 of the first preferred embodiment of the present invention can be applied to portable electronic devices, such as mobile phones.

[0020] The metal shell 10 includes a surface 12 on which a plurality of first patterns 122 arranged at intervals and a plurality of second patterns 124 arranged at intervals are formed on the surface 12. The plurality of first lines 122 have the same curvature, and the second lines 124 have the same curvature. The first pattern 122 and the second pattern 124 are reversely interlaced. The so-called reverse staggering means that the first pattern 122 and the second pattern 124 have an intersection, and the extending direction of the first pattern 122 and the extending direction of the second pattern 124 are symmetrical with respect to a straight line passing through the intersection. , And the straight line is located on a plane formed by the extending directions of the first pattern 122 and t...

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, the application of portable electronic devices such as mobile phones, PDA (Pe to personal Digital Assistant, personal digital assistant) and notebook computers is becoming more and more common. 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 of the product and cannot meet the requirements of consumers for the appe...
