Problems solved by technology

[0003] However, the surface formed by spraying and baking paint has poor wear resistance, is easy to wear and peel off, affects the appearance of the product, and cannot meet the requirements of consumers for the appearance of the product, and the surface formed by this method is very smooth and easy to slip off. product damage
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

[0016] The present invention provides a metal casing, and a preferred embodiment of the metal casing is applied to a mobile phone.

[0017] The surface of the metal shell has the appearance of wood grain texture. The wood grain can be engraved twice on the surface of the workpiece through wood grain engraving technology to remove excess material on the surface of the workpiece and repair the surface of the workpiece. There are differences in inter-space spacing and reverse staggering, resulting in the appearance of woodgrain texture. The material of the metal shell can be one of copper, iron, aluminum, stainless steel and titanium or an alloy of a combination thereof, and the material of the metal shell in a preferred embodiment of the present invention is aluminum alloy.

[0018] Please refer to Figure 1 for the manufacturing process of the metal shell with a wood grain surface. The manufacturing method specifically includes the following steps:

[0019] Stamping the metal s...

Abstract

The method is in use for forming timber grain with concavo-convex lines on surface of metal shell. The method includes following steps: punching sheet metal to form a metal shell; grinding, polishing the surface of metal shell, and then cleaning the surface by using alkali solution; using technique for carving timber grain to process the surface of the metal shell; finally, carrying out anodic treatment. The invention makes product possess natural appearance, antiskid function, as well as raise wear resistance of shell of product. Features are: simple manufacturing procedure, and easy operation.

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 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 surface formed by spraying and baking paint has poor wear resistance, is easy to wear and peel off, affects the appearance of the product, and cannot meet the requirements of consumers for the appearance of the product, and the surface formed by this method i...
