A metallic unpainted injection molding for a vehicle is disclosed. The metallic unpainted injection molding for a vehicle is molded by injecting metallic resins into a molding part inside an injection mold through a plurality of gates to be molded, wherein at least a groove line is molded in a boundary section where metallic resins meet each other in the molding part.

A method for producing a trim component for vehicle interior is disclosed. The method may produce multilayer molded bodies (e.g. interior compartments/fittings for vehicles) in which a reverse side of a leather material is backed with a plastic by injection molding. In order to prevent the leather material from being damaged by the injection pressures and/or temperatures during the in-mold injection molding process, the method provides for introducing untreated leather material into the injection mold.

To obtain a decorative film for insert molding, which is decorated by an ultraviolet curing ink-jet ink, and which exhibits excellent flexibility upon insert molding. A decorative film for insert molding, having on a film substrate a decorative layer formed from an ultraviolet curing ink-jet ink, wherein the elongation of the decorative film for insert molding is 150% or more under conditions at 180 C. and 50% or more under conditions at 25 C.

A method for producing a vehicle interior decorative part comprises providing a substrate film, forming a composite layer by applying a decorative ply to a first side of the substrate film, micro-perforating the decorative ply in one or more regions, inserting the composite layer made of substrate film and micro-perforated decorative ply into a cavity of an injection mold wherein, when plastics material is injected into the cavity, the decorative ply of the composite layer is back-injected and a second side of the substrate film opposite the first side is pressed against a wall of the cavity, closing the cavity and injecting plastics material into the cavity to form the decorative part substrate, the decorative ply being back-injected and the decorative ply being applied to a surface of the substrate facing the decorative ply during substrate formation in the cavity, and opening the cavity and removing the decorative part.

In a method for producing a component (500) from a translucent plastic material (50), which comprises a front side having n contours (51), and in particular n raised contours, and a rear side covered with a colored film (40), initially an injection molding tool (100) is provided, which comprises a first tool part (10) and a second tool part (20), which together enclose a cavity (30) having the contours of the component (500) to be produced when the tool is closed. A surface of the first tool part (10) represents a negative of the front side of the component (500) and comprises n structures (11), in particular n indentations, corresponding to the n contours (51) of the component. A surface of the second tool part (20) represents a negative of the rear side of the component (500). The film (40) is positioned on the surface of the second tool part (20). The injection molding tool (100) is closed, and plasticized plastic material (50) is injected into the formed cavity (30). After the plasticized plastic material (50) has cured, the component (500) provided with the film (40) is demolded. In this method, the surface of the second tool part (20) is provided with n elevations (21), and the film (40) is provided with n cut-outs (43), prior to positioning, such that the n elevations (21) on the surface of the second tool part (20) engage in the n cut-outs (43) of the film during the positioning of the film (40).

A method for producing a shaped part that includes: a decorative layer having a front/visible side and a rear/opposite side. The decorative layer has a recess extending into the decorative layer from the rear side. The shaped part includes an illumination and/or display unit with one or more illumination/display elements for displaying a notification on the front side, where the illumination and/or display unit comprises a base body made of a light-conducting material, the illumination and/or display elements are embedded in the base body, the base body is arranged at least partially in the recess in the decorative layer, the display elements are embedded in the base body, and the base body is arranged in the recess. Thus, light emanating from the illumination and/or display element(s) can be guided via the base body, towards the front side, and through the recess.

Provided is a decorated molding article includes a workpiece and a molded film attached to an outer surface of the workpiece or an inner surface of the workpiece. Compared with the printing layer in the conventional In Mold Label (IML) and InSert molding (INS) that is made by a plurality of anti-impact and bonding processes, a plurality of stacked decorative layers of the embodiment not only provide various color effects, but also directly combined with injection molding material to form part products and have both a protection effect and an adhesive effect. Further, the present disclosure can effectively simplify the manufacturing steps of the composite layer structure and reduce the manufacturing cost.
