A trim element, in particular for a vehicle interior, which conveys a particular aesthetic impression. A trim element with a first decorative layer that is light-transmissive at least in part between a light-transmissive intermediate layer on a rear side of the first decorative layer and a transparent cover layer and a second decorative layer of the intermediate layer on a front side of the second decorative layer and a carrier, where the second decorative layer is visible at least in part through the intermediate layer.

A toilet seat includes: a bottom plate including an engaging part; a top plate including a sidewall part provided on the bottom plate and a seating part supported by the sidewall part; and a bonding member having an exposed surface exposed externally. The engaging part is provided at a position opposing the sidewall part and has a recessed shape recessed downward. The sidewall part includes a sidewall base, a first hanging part extending downward from the sidewall base and engaging the engaging part, and a second hanging part provided to be separated from the first hanging part at the sidewall base to provide a recess recessed upward between the first hanging part and the second hanging part, the second hanging part being disposed at a position not overlapping the bottom plate. A side surface of the engaging part faces away and also extends away from the second hanging part.

Interior materials are attached to an outer surface of a plastic injection mold and expose, to outside, light selectively emitted from a light source arranged in the plastic injection mold. The interior materials include a wood pattern layer formed of natural wood and having a plurality of first lighting holes through which the light passes, a light block layer coupled to a rear surface of the wood pattern layer, blocking light, and having a plurality of second lighting holes formed therein corresponding to the plurality of first lighting holes, and a touch sensor electrode coupled to a rear surface of the light block layer. As texture of natural wood is embodied on the surface of the interior materials, and the surface of interior materials emits light and simultaneously, an operation of a preset function in the interior materials may be controlled by touching the surface of interior materials.

A housing for an electronic device comprising: a core layer comprising a first thermoplastic material; a first skin layer comprising a second thermoplastic material located on a first side of the core layer; a second skin layer comprising the second thermoplastic material located on a second side of the core layer opposite the first side; wherein the core layer comprises a foam structure, a honeycomb structure, or combinations thereof; and wherein the thickness of the core layer is 30% to 75% of the total thickness of the housing.

The invention relates to a method for producing a plastic molded part (1), comprising the steps of: a) providing a first decorative film (11), which at least partially has an opaque coating (112); b) introducing at least one decorative element of a decoration into the first decorative film (11) by machining using a machining tool; c) providing a second decorative film (12); d) placing the decorative films (11, 12) into an injection mold (2) having a first (21) and second mold half (22), which together form a cavity (23) for molding the plastic molded part (1), the first decorative film (11) being placed on a first wall (22f) of the cavity (23) and the second decorative film (12) on a second wall (21f) of the cavity (23) lying opposite the first wall (22f); e) back-injecting the decorative films (11, 12) with a polymer melt, so that the first decorative film (11) forms a first surface and the second decorative film (12) forms a second surface of the plastic molded part (1) opposite the first surface.

An injection-molding process for injecting a shoe soling including at least two adjacent injection-molding layers onto a shoe upper drawn over a shoe last, uses a mold cavity including a frame, the cavity being covered at the top by the upper also serving as a mold cover, with plastic material being injected into the cavity below the upper. To produce two adjacent injection-molding layers of plastic materials having different properties and reaction times in one operation, i.e. without needing an interim mold opening, before covering the cavity a film is clamped over it by a clamp mounted on the frame. When filling the cavity, the space below the film is first filled with plastic material to produce the first injection-molding layer and then, to produce the adjacent second injection-molding layer, the space above the film is filled with plastic material. Plastic materials are used that inseparably attach to the film.

A structural component, comprising at least two organo-sheet pieces which at least sectionally lie one on top of the other and which each include a fiber layer, wherein at least in the fiber layers of the organo-sheet pieces at least one pair of mutually aligned holes is formed, at which the organo-sheet pieces are positively connected to each other. There is furthermore proposed a method for manufacturing a structural component.

A method of joining a first workpiece substrate and a second workpiece substrate is disclosed in which a local mold tool is positioned into contact with the first workpiece substrate and the second workpiece substrate. The local mold tool defines a mold cavity and encloses an edge portion of the first workpiece substrate and an edge portion of the second workpiece substrate such that the edge portion of the first workpiece substrate and the edge portion of the second workpiece substrate are contained within the mold cavity. Once the local mold tool is positioned, a liquid polymer molding compound is injected into the mold cavity. The liquid polymer molding compound is hardened in the mold cavity into a polymer joint that adheres the edge portion of the first workpiece substrate and the edge portion of the second workpiece substrate together.

A molding tool and method for producing an interior trim part. A cavity is embodied between a first element and a second element, and a slide is displaceably connected to the first element. A decorative layer is arranged on the first element and a backing is arranged on the second element. A foamable mixture is added to the hollow area between the backing and a reverse side of the decorative layer, such that a foam layer fills the hollow area. A distance between the first element and the second element is increased to enlarge the hollow area. During this process, the slide is pressed against a side facing away from the reverse side of the decorative layer, such that the hollow area is sealed with the reverse side of the decorative layer pressed against a lateral surface of the backing and/or against a lateral surface of the second element.
