Field of the Invention The present invention relates to a method of manufacturing a housing, and more particularly to a method of manufacturing a housing for an electronic device. [Prior Art] With the rapid development of information technology, applications such as mobile phones, PDAs (Personal Digital Assistants) and notebook computers are becoming more and more popular, and the quality of these electronic devices outside the casing is high. And the degree of beauty is getting more and more attention and attention. In the prior art, a plastic material is often used as an electronic product casing. In order to improve the appearance of the electronic product casing and make the surface of the casing various in color, a paint layer is often used to form a paint layer on the surface of the electronic product casing to enable electronic production. ° mouth has a good appearance quality. However, the paint layer formed on the surface of the shell by the method of mouth coating is poor in abrasion resistance, easy to wear and peel off, and loses the luster texture. In addition, during the spraying process, it is easy to produce paint on the edge of the casing and the window, which affects the appearance of the product and does not meet the consumer's requirements for the appearance of the product. In order to make the surface of the casing have a glossy texture without spraying paint, the electronic device housing directly replaces the plastic material with a metal material. However, metal materials are expensive and have a negative impact on antenna performance. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a method of manufacturing a casing that has a glossy texture and is less prone to paint smear. 200944297 A method of manufacturing a casing, comprising the steps of: providing a transparent casing comprising an inner surface and an outer surface opposite the inner surface; printing ink on the inner surface of the casing to form a frame shape An ink zone and a window region located in the frame-shaped ink zone; shielding the window region of the inner surface of the casing and the frame-shaped ink zone; and baking the inner surface of the δ hai body; The outer surface is subjected to a non-conductive vacuum plating metallization process. By the method, the housing of the electronic product is manufactured to avoid the occurrence of overflow paint during the baking of the paint, so that the window area of the casing is covered with the paint body and the use of the electronic product is affected. At the same time, the Nc VM technology is used to perform a key film on the outer surface of the casing to make the appearance of the electronic product have a metallic f sense and does not adversely affect the antenna performance. [Embodiment] A method for manufacturing a casing according to a preferred embodiment of the present invention is described by taking a manufacturing of a mobile phone casing as an example. The manufacturing method includes the following steps: Refer to FIG. 1 'a transparent eve cat system 4 The pre-fabricated telephone housing 1〇〇 of the month, the housing 100 includes an inner cymbal and a a., . . . surface 10 and an outer surface 20 opposite the inner surface 10 'the housing 1 〇 The slanting position ϋ is provided with an opening 30 corresponding to the swaying telephone button area. The casing 100 is made of an injection molding machine, and the process is processed into a plastic material, which is injected into the machine. 200944297 · Such as acrylic (PMMA, polymethylmethacrylate) After the injection molding machine is cooled, the mold is opened, and a pre-fabricated mobile phone casing 100 which is transparent is formed. Referring to FIG. 2, the inner surface of the housing 100 is printed after the housing 100 is formed to define the transparent window region 40 of the mobile phone. The preferred embodiment of the present invention adopts a pad printing technology, the process of which is: firstly, a pad printing machine is provided, the pad printing machine comprises a rubber head disposed on the bottom of the embossing rod and a steel mold, wherein the steel mold is concavely provided with a rectangle The frame body is filled with ink. The rubber head is pressed against the steel mold by the embossing rod, so that the ink area 50 of the rectangular frame on the steel mold is absorbed on the plastic head. The adhesive head is then lifted by the embossing rod and moved over the inner surface 10 of the prefabricated housing 100, and then pressed down to transfer the ink zone 50 onto the inner surface 10 of the housing 100 for the shell A transparent window region 40 is defined on the inner surface 10 of the body 100. Each of the ink zones 50 has a certain width. Referring to FIG. 3 and FIG. 4 together, the window region 40 and the ink region 50 of the inner surface 10 of the casing 100 are shielded by the adhesive tape 60, and the edge of the opening 30 of the outer surface 20 of the casing 100 is shielded. Next, the inner surface 10 of the casing 100 is subjected to a baking finish. The baking process fixes the housing 100 to the upper fixture such that the inner surface 10 of the housing 100 is required to be opposed to the spray gun, and the paint body sprays the paint body to cover the inner surface 10 of the housing 100 with a paint layer. Since the adhesive tape 60 shields the ink zone 50 having a certain width, the edge of the opening 30 of the outer surface 20 of the casing 100 is shielded. If the lacquer phenomenon occurs at the edge of the bonding of the adhesive tape 60 and the ink zone 50 during the baking process, since the ink zone 50 has a certain width, it is possible to avoid the flooding of the lacquer liquid in the transparent window region 40. In addition, the edge of the opening 30 of the outer surface 20 is covered by the adhesive tape 60, so that even if the paint liquid flows onto the outer surface 20 during the baking process, the outer surface 20 can be prevented from being covered by the paint liquid. The housing 100 is then removed from the upper fixture and the adhesive tape 60 covering the edge of the opening 30 of the window region 40 and the outer surface 20 of the housing 100 is removed. Finally, the outer surface 20 of the casing 100 is subjected to NCVM (Non-Conductive Vacuum Metallization) technology to form a non-metal plating film having a metal light. By this method, the housing of the electronic product is manufactured to avoid the occurrence of paint varnish during baking, and the housing is more beautiful. At the same time, the outer surface of the casing is coated by NCVM technology, which gives the appearance of the electronic product a metallic feel without adversely affecting the antenna performance. It can be understood that if the mobile phone casing can also remove the opening, the step of shielding the opening can be omitted. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
