Description of the invention: * [Technical field to which the invention pertains] 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 matte effect on a surface of a casing. [Prior Art] As the level of consumption increases, consumers' demands for electronic products not only pay attention to their quality, but also pay more attention to the decorative effect of the surface of the outer casing. For example, some consumers prefer the shiny outer surface, while others prefer the matte surface of the outer surface. In order to achieve the matte effect of the outer casing, it is conventional practice to texture the surface of the formed outer casing or apply a matte finish coating on the outer surface of the outer casing. A process is added to achieve the matte effect, and the coating having a matte effect formed by coating is not wear-resistant, so that the coating is easily worn during use of the product, thereby affecting the appearance of the product. Moreover, the above two methods form a matte effect on the outer casing, and each of the formed outer casings needs to be separately processed, and the process is repeated and complicated, and the cost is 13⁄4. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a method of manufacturing a casing which can obtain a matte effect on the surface of the casing and which is simple to manufacture and low in cost. A method of manufacturing a casing for obtaining a matte effect on a surface of the casing, comprising the steps of: providing a molding die on which a texture having a matte effect is formed; providing a film and placing it In the mold; 6 201014496 injection molding a substrate layer on the film. - the method for manufacturing the casing of the present invention, by forming a matte surface and a texture of effect on the molding die, transferring the texture to the surface of the film when the base layer is injection molded, thereby making the casing surface while making the casing The matte effect is formed, the process is simple and easy, the cost is low in mass production, and the surface matte effect of the prepared shell surface is reproducible, which is beneficial to ensure the quality of the product. [Embodiment] The manufacturing method of the casing of the present invention is for obtaining a matte effect on the surface of the casing. The manufacturing method of the housing comprises the following steps: Referring to FIG. 1, a molding die 10 is provided. The molding die 10 includes a female die 11 and a male die 13 that cooperates with the female die 11. A cavity 110 is defined in the master mold 11, and a surface 112 of the cavity 110 corresponds to an appearance surface of a casing (not shown) to be formed. The male mold 13 is provided with a projection 130 whose surface corresponds to the inner surface of the casing to be molded. The molding die 10 can be selected in accordance with the shape or structure of the casing to be obtained. A matte effect texture is formed in the entire or a portion of the surface 112 of the cavity 110 of the master mold 11. The texture of the matte surface of the cavity 110 is such that the surface 112 of the cavity 110 is rendered non-smooth and diffusely reflected. The texture can be formed by spark discharge etching, chemical etching or sand blasting. The preferred embodiment forms the texture by spark discharge etching. Referring to FIG. 2, a plastic film 20 is provided. The material of the plastic film 20 may be selected from the group consisting of polycarbonate (PC), polyethylene terephthalate 201014496 (PET), polymethyl methacrylate (pMMA) or other transparent or opaque, plastic. A decorative layer 3 is provided on one surface of the film 20, such as a color map, a trademark or a trademark of a product. The decorative layer 3 can be an ink layer which can be formed by conventional screen printing.
