Description of the invention: [Technical field to which the invention pertains] The present invention relates to an in-mold method which refers to a method of obtaining a metallurgical method and the finished product. Injection molding method and its finished product, in-mold injection molding of a special product [Prior Art] Referring to Fig. 1, a conventional method of 佶揸 & amp && Because of the desired effect of the I decoration, the metal film 12 is formed in a touch-sensitive manner by forming a metal film 12 on the plastic film U: a pattern outline is formed, and an ink is overprinted on the metal film 12. The pattern 13 is such that the area of the ink pattern 13 has a metallic texture at the same time. Finally, the plastic film 11 is placed in a mold for in-mold injection molding to obtain a finished plastic product. However, since the process is to form a thin metal M 12 of a pattern wheel gallery, the ink pattern 13 is overprinted on the metal film 12. Therefore, in the process of overprinting the ink pattern 13, the outline of the ink pattern is often easily generated. The outline of the metal film 12 is slightly misaligned, so that a gap shadow is formed between the two, which affects the effect of the entire decorative pattern and the texture of the product. Referring to Fig. 2, an "in-mold decorative injection molding process" of the Republic of China application No. 941,874, which is similar to the formation of the metal film 15 before a plastic film 14, and then overprints the pattern 16, and finally The liquid plastic 17 is coated with the entire plastic film 14, the metal film 15, and the pattern 16 by injection molding. The above-mentioned conventional disadvantage is that, since the plastic film 14 is usually pre-processed to form a 3D structure, the metal film 15 is formed, and finally the ink film pattern 16 is printed on the 200904614, and the plastic film i4 has a molded outer shape. , the ink pattern 16 of the energy sleeve can generally only be confined to the local 2D plane of the plastic film crucible, and the ink pattern 16 cannot be distributed over the structure of 3 £>. In addition to the process, the process of coating the entire plastic film 14, the metal film 15 and the pattern 16 with the liquid plastic 17 requires not only the consumption of a large amount of the liquid plastic 17 but also the cost of the raw material, and if the process is It is only necessary to combine the liquid plastic 17 that is injected early in the plastic thin film to form the metal film 15 and the __ side of the figure 16, so that the liquid plastic (7) is more likely to be bonded to the plastic film 14 after it is suspected. Insufficient to separate from the plastic film 14, affecting the stability of product quality. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an in-mold injection molding method in which a process is relatively simplified and there is no problem that a decorative pattern of a finished plastic product and a metal film cause a problem of a defective shadow. Another object of the present month is to provide an in-mold injection molding method in which a decorative pattern can be distributed in a 3D structure so that the finished product has a metallic texture. A further object of the present invention is to provide a finished plastic product having a metallizing effect which is different from the conventional agricultural product and which can reduce the finished product. - A further object of the invention is to provide a finished metal product having a high stability of connection between plastics. Therefore, the in-mold injection molding method for making the finished product have a metallic texture is to form a decorative layer composed of a pattern, a pattern, a character or a color, and a metal film in a plastic film, and the decorative layer is interposed between the metal film and the metal film. After the plastic film is coated with an adhesive layer on the surface of the metal film, 200904614. Finally, it is placed in a mold for in-mold injection molding to obtain a plastic mouthpiece with a metallic shell and a decorative pattern with a stereoscopic effect. mouth. According to the in-mold injection molding method of the present invention, the metal-finished plastic product comprises a first plastic layer composed of the plastic film, a second plastic layer composed of injection molded plastic, and the like: (iv) a decorative layer between the layer and the second plastic layer, consisting of: a metal layer between the second plastic layer and - between the metal layer and the second plastic layer Adhesive layer. In the in-mold injection molding method for making the finished product have a metallic texture, after the metal thin film is formed, the decorative layer may be removed to obtain a metal thin film which is hollowed out, and the hollow film of the metal thin film is provided; The outline of the decorative layer is used to achieve the decorative effect by using the metal film alone and its hollowed-out area with a specific numb. By using the in-mold injection molding method of the present invention, the metal film is formed by forming the decorative pattern first, not only omitting the conventional step of the metal film, but also avoiding the occurrence of the decorative pattern during the overprinting process. The difference between the yin and the yin (4) (4) is the effect, and the result is (4) in the conventional == decorative effect... In addition, since the present invention is formed first, the material is thinned and the H-shaped solid structure is added. In this way, the decorative pattern is distributed on the three-dimensional structure, and the defect can be printed on the plane.
