Description of the Invention: [Technical Field] The present invention relates to a method of manufacturing a casing, and more particularly to a method of manufacturing a casing which can obtain a drawing effect on a surface of a casing. [Prior Art] With the improvement of the consumption level, the consumer's demand for electronic products not only pays attention to the decorative effect of the surface of the shell. For example, some of the singulars prefer the surface of the outer shell, while others prefer the matte or silky outer surface. In order to meet the needs of different preferences (four), there are also producers who make the surface part of the product shell shine, and other parts = the effect of pulling 4 . This kind of product is usually made by molding the outer casing first, and then drawing a part of the surface of the 5 hai shell by a special machine to form a wire drawing effect. The side seeding method needs to use an additional wire drawing machine to draw the surface of the outer casing. The cost of the wire drawing machine equipment, on the other hand, increases the process of pulling, and the work process is bound to increase the cost of the product and reduce the competitiveness of the product. SUMMARY OF THE INVENTION [2] In the present invention, it is necessary to provide a method for manufacturing a casing which can obtain a drawing effect on the surface of the casing and which has an early appearance and a low cost. A method for fabricating two kinds of shells for obtaining a drawing effect on the surface of the casing, comprising the steps of: providing a forming mold, forming a drawing texture on the forming mold; providing a film and placing it in the mold Medium; molding a substrate layer on the film. The manufacturing method of the casing of the present invention is formed by forming a drawing pattern 201002542 on a forming mold, transferring the drawing texture to the surface of the film when the base layer is injection molded, ... (4) forming a shell to reduce the surface of the shell Texture, its work peek = easy to operate, low cost, and the surface effect of the shell produced ^ to ensure the quality of the product. The invention is advantageous for the method of manufacturing the casing of the present invention for obtaining the drawing effect on the surface of the casing. The method of making 5 忒 包括 includes the following steps: 'Providing — forming a mold. The molding die includes a master die and a disk which are fitted with a male die. The master die is provided with a cavity which corresponds to the appearance surface of the molded casing. The surface of the male mold is provided with a surface = the surface corresponding to the inner surface of the casing to be formed. The forming die is selected to be such that the shape or structure of the casing is desired. U is formed according to the texture of the whole or a part of the surface of the cavity of the above-mentioned mother mold. Miscellaneous, compared with the material by (4) _, cut = square material. This embodiment uses a misprinted money engraving to form a brushed pattern. - Plastic film. The plastic thin material (10), polyethylene terephthalate (PET) \ self-made::: "曰 (mMA) or other transparent or opaque plastic. In the thin; methyl vinegar can be set - decorative layer 'such as Color pattern or product: Earth 'eight' is formed by "see screen printing." The film forming the decorative layer is pushed into the shell of the itn-shaped makeup., _ ^ is cut and hot-pressed into the side of the body to be formed, and the sub-district and the (four) heart are convex surfaces, and The decorative layer is combined with the surface of the surface 31 to be formed into a concave surface, and then 201002542 is placed in the cavity of the mother mold, and the (10) surface of the film is attached to the cavity. And clamping the male mold and the female mold, and injecting a base layer on the decorative layer of the concave surface of the film. The material for injection molding the base layer may be selected from the group consisting of polyethylene (PE), polyamine (PA), polycarbonate (PC), propylene-styrene-butadiene copolymer (ABS), and polyfluorene. Any of various plastics such as methyl acrylate (pMMA) or polyethylene terephthalate (PET). After the injection molding of the base body, the Vieirai has a force of about 2G to 3G seconds before cooling, and in this process, the part of the mold cavity formed with the brushed texture acts on the convex surface of the film in the high temperature and high pressure environment, thereby A drawing effect complementary to the brushed texture in the cavity of the master mold is formed on the convex surface. After the drawing texture is formed on the film, the casing of the mold is cooled and cooled. After cooling, the male mold and the female mold are placed, and the casing is taken out. The manufacturing method of the casing of the present invention can be applied to the manufacture of a casing of an electronic product such as a mobile phone, a computer, a music player, and the like, and can also be applied to a daily decoration or a glasses case, a gift box, etc. which can be molded by injection molding. The surface has a brushed effect. The manufacturing method of the casing of the present invention is to form a drawing texture on the surface of the forming mold, and the drawing texture is transferred to the surface of the film when the base layer is injected, and the surface of the casing is formed into a wire-drawing texture while the casing is being formed. The process is simple and easy, the cost is low, and the surface effect of the prepared shell is reproducible, and the quality of the product is ensured.
