Problems solved by technology

The above-mentioned methods of forming weaving patterns on the surface of the shell need to be carried out under high temperature and high pressure, which will easily cause thermal deformation of the fiber material, thereby affecting the appearance of the product and resulting in a decrease in product yield
In addition, the above method can only be applied to plastic shells at this stage, and it is difficult to realize the weaving and patterning of its appearance on metal shells

Embodiment Construction

[0018] The manufacturing method of the shell of the present invention is used to obtain the weaving pattern effect on the surface of the shell. The manufacturing method of the shell comprises the following steps:

[0019] see figure 1 As shown, a film 10 is designed and manufactured, and a light-shielding area 11 and a plurality of light-transmitting areas 13 are formed on the film 10 . The light-shielding area 11 is coated with a photosensitive material, such as opaque photosensitive glue. The light-transmitting regions 13 are arranged in a matrix, which are transparent films and not coated with photosensitive materials.

[0020] see figure 2 As shown, a housing 20 is provided. The shell 20 can be a metal shell, such as aluminum, aluminum alloy, titanium, titanium alloy or stainless steel, or can be a plastic shell. The appearance surface of the casing 20 includes several shielding areas 23 and the first brushed area 21 surrounding the several shielding areas 23 . The ...

Abstract

The invention discloses a manufacturing method of shell, which is used for causing the surface of the shell to obtain weaving pattern effect, comprising the following steps: designing and producing a film provided with a shading zone and a photic zone; providing a shell, and coating photosensitive material on the shell; sticking the film to the shell, and exposing the film so as to cause the photosensitive material corresponding to the film photic zone on the shell to generate photoreaction for solidification; removing the film, and cleaning the photosensitive material corresponding to the film photic zone on the shell, which exposes the zone on the shell; performing first-time wire drawing to the shell, and forming wire drawing grains on the bared shell; shading parts of zones forming the wire drawing grains on the shell; performing the second-time wire drawing to the shell in different directions.

Description

technical field [0001] The invention relates to a manufacturing method of a casing, in particular to a manufacturing method of a casing capable of forming colorful weaving patterns on the surface of the casing. Background technique [0002] With the improvement of consumption level, consumers not only pay attention to the quality of electronic products, but also pay more and more attention to the decorative effect of the shell surface. The shell with weaving pattern is very popular among consumers because of its novel and beautiful appearance. Existing methods for forming weaving patterns on electronic product casings usually include impregnating the weaving fibers in resin and forming them together with the resin by heating, pressurizing and hardening, or selecting fabrics with weaving patterns, such as cloth, using IML (in-mold Insert injection molding) process to bond it to the surface of the plastic housing. The above-mentioned methods of forming weaving patterns on th...
