  • Patent number: 9469079
    Abstract: A cover member of an illuminating unit is formed of a film insert molded product, in which a film is disposed on a decorative face. The film is arranged so an end part of the film is positioned in front of an end part of the decorative face, whereby a film end protecting area formed of an exposed part of a molded resin layer is provided between the end part of the decorative face and the end part of the film, and a surface of the film end protecting area is made flush with the surface of the film. A corner between the end part of the decorative face and an end face of the molded resin layer is set to be an acute angle, and the end face of the molded resin layer functions as a contact face with respect to a ceiling trim.

  • Patent number: 8728577
    Abstract: Provided is a production method of a metallic decorative sheet capable of preventing from getting detached at edge portions. The production method of a metallic decorative sheet for insert molding comprises steps of forming a metal thin-film layer 12 on a back surface of a transparent thermoplastic resin film 11; removing a first region J for displaying a non-metallic design on an outer surface of the thermoplastic resin film 11 and a second region K which is at least a part of edge region of the thermoplastic resin film 11 from the metal thin-film layer 12; and laminating an ink layer 14 on at least the metal thin-film layer 12 and the second region K.

  • Publication number: 20130108838
    Abstract: A film insert molded product is molded by injecting molten resin into a mold, after a film has been set on a cavity face of the mold, and then, hardening the resin. A back face of the film and a surface of a molded resin layer are adhered to integrate each other, and the film is disposed on a decorative face of the molded product. The film is so arranged that an end part of the film is positioned in front of an end part of the decorative face, whereby a film end protecting area formed of an exposed part of the molded resin layer is provided between the end part of the decorative face and the end part of the film, and a surface of the film end protecting area and the surface of the film are formed in flush with each other.

  • Patent number: 7655163
    Abstract: A manufacturing method of a film insert molded article in which no resin layer is seen in the front and no wrinkle is generated in a film is provided. A thermoformed film (11) for coating is arranged within a cavity (15), and molten resin is injected so that a film insert molded article (50) molded integrally with the film (11) for coating and having a coating plane coated with the film (11) for coating is obtained. A printing ink layer (20) and a binder layer (30) are formed in a raw material film (10). The raw material film (10) is cut out and the film (11) for coating is formed so as to have a size for coating the coating plane and being able to form an outer circumferential bending portion (12) arranged in an outer circumferential side portion (41) by adding a width exceeding a heat shrinking amount of the film.

  • Publication number: 20090226649
    Abstract: An insert molded article is comprised of a thermoplastic resin molded article and a thermoplastic resin film-like body molded integrally with the molded article by insert molding. The film-like body is heated, during insert molding, to a temperature in which a secondary shrinkage factor thereof becomes equal to or larger than a shrinkage factor of the thermoplastic resin of the molded article. A manufacturing method of the insert molded article includes providing the thermoplastic resin film-like body to a concave portion of a female mold, forming a cavity of a shape capable of shaping the molded article on one surface of the film-like body, and injection molding the thermoplastic resin so that the film-like body is heated, inside the cavity, to a temperature in which the secondary shrinkage ration thereof becomes equal to or larger than the shrinkage ratio of the thermoplastic resin forming the molded article.
