A method for manufacturing the panel element () according to an aspect of the present invention includes: a process of printing a printed layer () formed of an ink that does not transmit light on a front side of a resin sheet (); a process of superimposing and printing a printed layer () on an upper surface of the printed layer () to form a laminated printed layer (); and a process of irradiating the laminated printed layer () with laser light on a front side thereof to remove a part of the laminated printed layer () and to form a hole portion having a vertical end face in the laminated printed layer ().

Method for manufacturing panel element

A production method of a metallic decorative sheet () which is insert-molded integrally with a thermoplastic resin molded body () to constitute an insert molded body () has steps of: laminating a specular ink layer () on one surface of a transparent thermoplastic resin film () in a region except an edge region serving as an edge portion of the insert molded body () and in a region for displaying a metallic design on an outer surface of the insert molded body (), and laminating a non-specular ink layer () on the specular ink layer () and on the surface of the transparent thermoplastic resin film () where the specular ink layer () is not laminated.

Production method of metallic decorative sheet, and production method of insert molded body using the metallic decorative sheet

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 layeron a back surface of a transparent thermoplastic resin film; removing a first region J for displaying a non-metallic design on an outer surface of the thermoplastic resin filmand a second region K which is at least a part of edge region of the thermoplastic resin filmfrom the metal thin-film layer; and laminating an ink layeron at least the metal thin-film layerand the second region K.

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 () for coating is arranged within a cavity (), and molten resin is injected so that a film insert molded article () molded integrally with the film () for coating and having a coating plane coated with the film () for coating is obtained. A printing ink layer () and a binder layer () are formed in a raw material film (). The raw material film () is cut out and the film () 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 () arranged in an outer circumferential side portion () by adding a width exceeding a heat shrinking amount of the film. After the film () for coating is preheated, the film () for coating is thermoformed so that a predetermined three-dimensional shape () and the outer circumferential bending portion () are formed. The film () for coating in which the three-dimensional shape () and the outer circumferential bending portion () are formed, is arranged within the cavity () such that the binder layer () comes into contact with molten resin. The molten resin is then injected.

Manufacturing method of film insert molded article

A display panel which is adapted to be mounted on an electronic apparatus, includes a first printed display layer, a transparent material layer that is provided on the first printed display layer, and a second printed display layer that is provided on the transparent material layer so as to correspond to the first printed display layer. The first printed display layer, the transparent material layer and the second printed display layer are integrally formed to each other. The second printed display layer is displayed from the first printed display layer side through the transparent material layer.
