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, reducing its competitiveness in the field of decorative coatings

Embodiment Construction

[0016] see figure 1 , the housing 10 of a preferred embodiment of the present invention is described by taking a mobile phone housing as an example. The casing 10 includes a base 11 , a bonding layer 13 and a color layer 15 . The combination layer 13 is disposed on the surface of the substrate 11 , and the color layer 15 is disposed on the surface of the combination layer 13 .

[0017] The substrate 11 can be metal material or non-metallic material such as glass and plastic.

[0018] combined reference figure 2 , provide a coating machine 100, the coating machine 100 includes a coating chamber 20 and a vacuum pump 30 connected to the coating chamber 20, the vacuum pump 30 is used to evacuate the coating chamber 20. The coating chamber 20 is provided with a turret (not shown) and symmetrically arranged titanium targets 22 . The turret drives the substrate 11 to revolve along the circular trajectory 21 , and the substrate 11 also rotates when revolving along the trajectory 2...

Abstract

The invention provides a shell, which comprises a matrix, a bonding layer and a color layer. The bonding layer is formed on the surface of the matrix. The color layer, being a Ti-O-N film, is formed on the surface of the bonding layer. A chroma region presented by the color layer has an L* coordinate value ranging from 42 to 55 in a CIELAB color system, an a* coordinate value ranging from 5 to 18, and a b* coordinate value ranging from 6 to 15. The invention also provides a making method of the shell. The shell shows an orange red appearance, and enriches vacuum coating colors.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to an orange-red and metallic 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 sur...
