Description of the Invention: [Technical Field] The present invention relates to a method for fabricating a decorative film. [Prior Art] Conventionally, the casing of a portable electronic product is mostly manufactured by an IML (In-Mold Film Injection Molding) process. The outer casing made by this process usually comprises a transparent plastic φ film, a trademark or pattern formed on the surface of the plastic film, and a plastic substrate layer on the film and the trademark or pattern. The film needs to have a certain hardness to ensure the implementation of the subsequent hot press forming process, and the film has better wear resistance. At present, in order to make the surface of the film have a soft touch = the usual method is to spray on the surface of the film - a soft touch of the skin 2 layers. Since the leather lacquer layer is disposed on the thin appearance surface, and the skin/layer does not have strong abrasion resistance, the effect of the material is lost. ❹ [Summary of the Invention] The touch film is provided with a decorative film which has both a soft touch and a strong abrasion resistance. The body is not only required to provide a casing for applying the above decorative film, and the shell has a strong abrasion resistance and a better use effect. Second = it is necessary to provide a method of manufacturing the above casing. ^, comprising a first film layer and a first film; a 1 -th thin layer and a second thin layer - phase layer, the casing comprising a soft touch layer. An outer skin layer and a substrate 6 201008795 layer bonded to the outer skin layer, the outer skin layer includes a first film layer and a second film layer, and a soft layer is disposed between the first film layer and the second film layer Touch layer. A method of fabricating the above-described housing includes the steps of: providing a thin film layer, a second film layer and a soft touch layer; providing two relatively rotating rollers, a narrow gap formed between the two rollers Sewing the two rollers to rotate relative to each other, and passing the first film layer, the soft felt layer and the second film layer to each other through the slit between the two wheels, the first film The layer, the soft touch layer and the second film layer are laminated into one body; a base layer is bonded to the surface of the second film layer. The housing of the present invention has a soft touch feeling by pressing a soft touch layer between the first film layer and the second film layer, and since the film layer still serves as an appearance surface of the outer skin layer The appearance and wear resistance of the casing will not change, and the soft touch will not be lost due to wear during use, and the use effect is better.实施 [Embodiment] Referring to Figure 1 of the preferred embodiment of the present invention, the housing includes an outer skin 11 and a base layer 15 bonded to the outer skin n. Referring to FIG. 2, the outer surface layer 11 includes a decorative film and a decorative layer 117. The decorative film includes a first film layer ηι, a soft touch layer 113 bonded to the first film layer ill, and a bonding layer. The second film layer 115 of the soft touch layer ιΐ3. The decorative layer 117 is disposed on the surface of the second thin layer relative to the soft touch layer 113. The first film layer 111 is made of transparent plastic, and the plastic may be selected from the group consisting of polypropylene 7 201008795 olefin (PP), polyamine (PA), polycarbonate (PC), polyethylene terephthalate (PET). Or any of the polymethyl methacrylate (PMMA). The soft touch layer 113 can be a soft silicone layer which has a soft touch and is transparent. The thickness of the soft touch layer 113 may be equal to or slightly larger than the thickness of the first film layer 111. / The material and thickness of the second film layer U5 may be the same as that of the first film layer U1.

The base layer 15 is a plastic layer which can be formed on the decorative layer 117 by injection molding. The material forming the base layer 15 may be selected from the group consisting of ethylene (PE), polycarbonate (P(:), acrylonitrile-styrene-butadiene copolymer (ABS), polymethyl methacrylate (pMMA). Or a plastic such as polyethylene terephthalate (PET). A preferred embodiment of the present invention for manufacturing the housing 10 includes the following steps: Referring to FIG. 3, a first film layer is provided. , a * JS 11-2 a permanent soft touch layer 113 and a second film layer 115. The first film layer ill is made of transparent plastic, the plastic may be selected from polypropylene (PP), polyamine (PA) Any of polycarbonate (PC), polyethylene terephthalate (PET) or polymethyl methacrylate (PMMA). The soft tactile layer 113 can be a soft silicone layer, the soft The silicone rubber has a soft touch and is transparent. The thickness of the soft touch layer 113 may be equal to or slightly larger than the thickness of the second film layer 111. ' 8 201008795 The second film layer 115 The material and thickness may be the same as those of the first film layer 111. Two rollers 17 and 19 are provided, and the surfaces of the two rollers 17, 19 are flat. 17 is rotated relative to the roller 19 on the same horizontal surface. For example, the roller 17 rotates clockwise, the roller 19 rotates counterclockwise, and a slit 20 is formed between the roller 17 and the roller 19, the slit The width of 20 is slightly smaller than the sum of the thicknesses of the first film layer 111, the soft touch layer 113 and the second film layer 115. The two rollers 17, 19 are relatively rotated, and the first film is The layer 111, the soft touch layer 113 and the second film layer 115 protrude into each other into the slit 20 formed by the roller 17 and the roller 19 when the contract is applied to each other. The first film layer 111, the soft touch layer 113 and the second The film layer 115 is simultaneously moved downward under the pulling of the roller 17 and the roller 19, and one surface of the first film layer 111 is crushed by the roller 17, and one surface of the second film layer 115 is pressed by the roller 19. When the first film layer 111, the soft touch layer 113 and the second film layer 115 are all passed through the slit 20, the first film layer 111, the soft touch layer 113 and the second film layer 115 are combined.
