Problems solved by technology

However, plastic shells and painted shells cannot present a good metallic texture
On the other hand, because the vacuum coating technology itself is relatively complicated and difficult to precisely control, the color of the metal vacuum coating layer formed on the surface of the shell in the prior art is limited. Compared with baking paint, anodizing and other processes, the color of the vacuum coating layer is not enough. rich, limiting its competitiveness in the field of decorative coatings
At the same time, the wear resistance of the color film layer sputtered by PVD is generally poor, so that the shell will be discolored and peeled off during use, and it is difficult to maintain a long-term good decorative appearance

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof. Background technique [0002] With the continuous advancement of technology, various electronic devices such as mobile phones, personal digital assistants (PDA, Personal Digital Assistant), and computers are also developing rapidly, and their functions are becoming more and more abundant. In order to make the casing of the electronic device rich in color, traditionally, colored plastics can be used to form the colored plastic casing, or a color layer is formed on the surface of the casing of the electronic device by spraying paint. However, plastic shells and painted shells cannot present a good metallic texture. On the other hand, because the vacuum coating technology itself is relatively complicated and difficult to precisely control, the color of the metal vacuum coating layer formed on the surface of the shell in the prior art is limited. Compared with baking paint, anodizing an...
