no. 1 example

[0025] See figure 1 , figure 1 It is a manufacturing method of a shell provided by the first embodiment of the present invention, wherein the shell can be applied to any electronic device with a shell, such as a mobile phone, a computer, a tablet computer, a notebook computer, a personal digital assistant, a mobile Internet device Or wearable devices, etc. The manufacturing method of the shell includes:

[0026] S1: Please refer to image 3 , provide a shell material 100, the shell material 100 can be made of alloy (such as aluminum alloy).

[0027] Preferably, the shell material 100 can also be pre-treated. Taking the shell material 100 as an example made of aluminum alloy, the pre-treatment steps of the shell material include:

[0028] S10: Cutting the aluminum alloy to the required size, and then processing the inner cavity and the positioning column on the aluminum alloy to obtain a shell material intermediate.

[0029] S11: slotting the shell material intermediate to...

[0046] Please refer to figure 2 , figure 2 It is a method of manufacturing a casing provided by the second embodiment of the present invention. The difference from the first embodiment is that between steps S3 and S4:

[0047] S31: In the optical coating machine, alternately coat 3-6 layers of different coating materials on the color paint layer 40 according to the preset reflectance and transmittance, thereby forming an optical coating layer 30 . The optical coating layer 30 is used to increase the metallic luster of the shell material 100 . The material of the optical coating layer 30 is any one of titanium dioxide and silicon dioxide. The thickness of each layer of the optical coating layer 30 is 20-30 μm.

[0048] Preferably, in order to enhance the bonding force between the optical coating layer 30 and the color paint layer 40, a coating primer layer 60 can also be sprayed between the optical coating layer 30 and the color paint layer 40 Similarly, in order to enhan...

Abstract

The invention provides a manufacturing method of a shell. The manufacturing method comprises the following steps of providing a shell material, and spraying primer on the shell material to form a primer layer; spraying colored paint on the primer layer to form a colored paint layer; and spraying finish paint on the colored paint layer to form a finish paint layer so as to obtain the shell with high glossiness. The shell is made of metal or a complex of metal and plastic; the primer layer and the colored paint layer contain zirconium oxide powder; the mass percentages of the zirconium oxide powder in the primer and the colored paint are 1%-5% and 0.1%-1% correspondingly; and the primer layer, the colored paint layer and the finish paint layer are repeatedly sprayed and cured for at least three times. The invention further provides the shell manufactured according to the method, and the shell has high glossiness and metallic luster.

Description

technical field [0001] The invention relates to a metal casing, in particular to a metal casing with baking paint on the surface and a manufacturing method thereof. Background technique [0002] With the improvement of living standards, people have higher and higher aesthetic requirements for the appearance of various items (including electronic equipment products) used in daily life. The appearance of electronic equipment products has attracted widespread attention, and the surface treatment of product casings is also pursuing beauty and style. [0003] In the prior art, a paint layer is usually formed on the surface of the housing by spraying and baking paint, but the paint layer has poor wear resistance and is easy to wear and peel off during use, resulting in loss of luster. Contents of the invention [0004] The object of the present invention is to overcome the disadvantages of the prior art, and provide a casing and a manufacturing method of the casing, so as to so...
