Field of the Invention The present invention relates to a method of manufacturing a casing and a casing obtained by the method, and more particularly to a method of manufacturing a casing having a color gradation effect and Method of making the shell. [Prior Art] The IML process is currently widely used in the manufacture of sturdy electronic housings. The red-difficult casing usually comprises a transparent, wear-resistant and scratch-resistant plastic film on the outer surface of the casing on the outer surface of the ink layer and a base layer on the inner surface of the ink layer. The lion ink layer is sandwiched between the thief and the plastic substrate layer. During use, the ink can be prevented from falling off and being worn away. Therefore, the product can be kept for a long time, and the product is favored by the material. However, _ ink layer pass: = now a single color 'can not present multiple colors at the same time, with color [invention content] yue # this is necessary to provide a shell with a color gradient effect, the other side is necessary Provide the shell made by the method of Shangfa. - a method of manufacturing a casing, comprising the steps of: providing a plastic substrate; forming a primer layer on the surface of the Nakis; forming a vacuum having a metallic appearance; forming a transparent layer on the vacuum coating layer Forming a second-translucent 201103777 first-color lacquer layer on the surface of the plastic base-shaped lacquer layer, the second lacquer layer having at least a portion of the second lacquer layer The lacquer layer includes a shielding area and a transition area connected to the shielding area, and the paint density of the transition area gradually decreases from a position of the transition area adjacent to the shielding area to a direction in which the transition area borders the first color lacquer layer; Forming a transparent topcoat layer on the surface of the second color lacquer layer and the first color lacquer layer not covered by the second color lacquer layer. - a shell 'includes a --valve body, formed on the bottom of the surface of the base

The first color lacquer layer is formed directly on the surface of the vacuum lamina. The second color lacquer layer is formed on the first color lacquer layer, wherein few of the factory parts and the first color lacquer layer fall. The second color lacquer layer includes a masking area and a transition area. The masking area shields a portion of the first color lacquer layer. The paint forming the transition zone is from the transition zone adjacent to the cover position to the boundary between the transition zone and the first color lacquer layer. The topcoat layer is formed on the surface of the first color lacquer layer and the first color lacquer layer which is not necessarily covered by the second color lacquer layer. Compared with the prior art, the manufacturing method of the present invention is to spray a two-color paint layer on the first color paint layer, and to transfer the paint forming the second color paint layer to the first color paint layer. Square = evenly distributed until disappeared, so that the color of the second color lacquer layer and the third color: 曰 '贞 color 1 plus blending, thereby achieving the transition from one color to another _ [embodiment] = The manufacturing method is used to produce a housing having two or more colors, effects, and a touch. The following is an example of making a housing having two color gradient effects and a green hand feeling. 201103777 Please refer to FIG. 1 and FIG. 3, the manufacturing method of the preferred embodiment of the present invention includes the following steps: & (Figure 3 ·· Provided - plastic substrate u. Plastic matrix type, which has to be made The structure of the shell.

And poly-p-benzene step S2: Yu Qingji _ surface formation) Increase the adhesion of the substrate u to the subsequent film = cured paint layer. _ t is 1 external 13 formed on the primer layer 12 - a vacuum coated household having a metallic appearance 13 . When the casing 1 is used for the non-conductive vacuum/product shell of the shooter forging layer 13, the vacuum coating vacuum forms the vacuum mineral layer 13 by vacuum steaming or brightening* : Forming (e.g., spraying) - a transparent or translucent one-color lacquer layer 14 on the vacuum film layer 13. The first color paint sound 14 months old and abundant layer 14 covered true reading film 13 4 J color first color paint empty surface layer 13 all sound. ^ P Surface 'This embodiment covers the true cured paint. The paint of the first color paint layer 14 can be directly formed on the first color paint layer 15 of the first color paint. The second color lacquer layer 15 can cover part of the surface of the vacuum film layer 13 曰. When the first color paint layer 14 is partially overlapped to form the paint layer 15, the first color paint layer 14 may be formed on the real paint layer 13. The second color 201103777 of this embodiment is formed on a partial surface of the first color lacquer layer 14. • The second color lacquer layer U has a second color different from the first color lacquer layer 15. The second color lacquer layer 15 can be an ultraviolet curable paint. The second color lacquer layer 15 includes a masking area 152 and a transition zone 154. The paint of the masking area 152 is relatively thick, so that the masking area 152 completely shields the first color lacquer layer 14 corresponding to the area. The transition zone 154 is the junction zone where the second color lacquer layer 15 transitions to the first color lacquer layer μ. The paint distribution of the transition zone 154 is relatively thin, so that the transition zone 154 has not completely obscured the first color lacquer layer 14 corresponding to the zone. The paint density of the transition zone 154 gradually decreases from the position where the transition zone 154 abuts the shadow zone 152 toward the boundary of the transition zone 154 with the first color lacquer layer 14. Preferably, the paint of the transition zone 154 is gradually and uniformly thinned from the position where the transition zone 154 abuts the shadow zone 152 to the boundary of the transition zone i54 and the first color lacquer layer 14 until it disappears. Please refer to FIG. 2 at the same time, the specific method of spraying the second color paint layer u is as follows: first fix the plastic substrate 11 to be sprayed, take a plurality of spray guns 2 (such as 3 to 4), and fix a plurality of branches respectively. The relative position and angle of the sprayed 20 with the plastic substrate u to be sprayed. Then, based on the atomization pressure and the oil output of the sprayed area of the masking area, the atomization pressure and the oil output of the remaining sprays 20 are adjusted, so that the atomization pressure of each spray 20 is The distance between the sprayed area of the sprayed shot 20 and the shaded area 152 is increased (the larger the atomization pressure of the spray is, the smaller the sprayed paint particles are), and each shot is rushed out. The amount of oil decreases as the distance between the area where the spray gun 20 is sprayed and the shaded area 152 increases (the smaller the amount of oil discharged, the thinner the concentration of the sprayed paint). Finally, the plastic substrate 11 can be simultaneously sprayed using the plurality of sprays 20. Step S6: forming a transparent topcoat layer 16 on the surface of the second color lacquer layer 15 and the first color lacquer layer 14 not covered by the second color lacquer layer 15. The topcoat layer 16 can be a leather lacquer layer having a soft hand. 201103777

The masking zone 152 completely obscures the first color lacquer layer 14 corresponding to the area. The transition zone 154 is the junction zone where the second color lacquer layer 15 transitions to the first color lacquer layer 14.
