A method for manufacturing a seat shell for a chair includes three method steps (a) to (c). According to a first step (a), a carrier made of a plastic material is provided, on the front side of which a plastic film is arranged. According to a second step (b), the carrier with the plastic film is deep drawn by a deep drawing tool such that the front side of the carrier with the plastic film has a predefined three-dimensional surface contour after the deep drawing. According to a third step (c), a rear side of the carrier is encapsulated by injection molding with the plastic material.

The present invention discloses a keycap for keys of a keyboard device, wherein the keys are configured on the keyboard, and the keycap is configured on a key body. The keycap includes: a top fabric layer, a keycap body including an upper surface outline, and a molding film. The top fabric layer is used for engraving to have a symbol thereon to transmit light therethrough, wherein each symbol indicates a specific keycap. The molding film is disposed between the top fabric layer and the keycap body to render the top fabric layer in a specific shape matching with the upper surface outline. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

A method for manufacturing an electromechanical structure includes producing conductors and/or graphics on a substantially flat film, attaching electronic elements on the film in relation to a desired three-dimensional shape of the film, forming the film into the substantially three-dimensional shape, and using the substantially three-dimensional film as an insert in an injection molding process by molding substantially on said film.

A system for manufacturing an electromechanical structure includes first, second, and third entities. The first entity produces conductors on a planar, flat film. The second entity attaches electronic elements at locations on the film in relation to a three-dimensional shape of the film. The electronic elements include a number of surface mount technology components. The locations of the electronic elements are selected to omit substantial deformation during subsequent forming of the film into the three-dimensional shape. The third entity forms the film into the three-dimensional shape when the electronic elements are supported on the film. The third entity includes one or more machines that are continuously roll-fed, automatically in-precut-pieces-fed, computer numerical control, thermoforming, vacuum former, pressure forming, or blow molding. The first, second, and third entities are arranged relative to one another to manufacture the electromechanical structure.

An injection molding apparatus is equipped with a first mold and a second mold. The first mold or the second mold includes sliding members that are inserted into holes formed in a workpiece. The sliding members are capable of being displaced in a direction to approach toward or separate away from a cavity formed by the first mold and the second mold.

A resin molded article is equipped with a laminated body in which a core material layer, a cushion layer, and a skin layer are included and laminated. In this configuration, a lowermost layer and a peripheral edge portion of the laminated body are covered by a resin covering layer, and only the upper surface of the skin layer is exposed and serves as a design surface. Moreover, the peripheral edge portion of the laminated body is embedded in an interior part of the resin covering layer.

A cover for a radar sensor for motor vehicles, which has a wall provided with a three-dimensional relief structure, in which the wall including the relief structure is made of deep-drawn glass.

A system for carrying out a manufacturing method of an electromechanical structure apparatus includes an entity for producing conductors on a flat film, an entity for attaching electronic elements at locations on the flat film in relation to the desired three-dimensional shape of the flat film, the electronic elements including a number of SMT components, the locations of the electronic elements on the flat film selected such that the locations omit substantial deformation during subsequent 3D forming of the flat film, an entity for forming the flat film into a three-dimensional film and an entity for injection molding.

The main subject matter of the invention is a method for manufacturing a plastic part forming a human-machine control interface, characterised in that it comprises the following steps: formation of a decorative film; formation of a technical film including a layer of haptic actuators and a layer of capacitive sensors; assembly to form an interface film (6); positioning in an injection mould (7), including an upper portion (7a) and a lower portion (7b) including a moveable support pad (8) capable of coming into contact with the interface film (6) such that a thickness (E) is left free between the interface film (6) and the lower portion (7b) of the injection mould (7) outside of the support pad (8); injection of a plastic material into the free thickness (E) on either side of the support pad (8); opening of the injection mould (7) and ejection of the plastic part formed.

A vehicle interior board which has less deterioration and peeling near an end portion of a metal plate, has high quality, is thin, lightweight, and has high strength and excellent productivity. The vehicle interior board includes a pair of metal plates and a foamed polyurethane layer formed between the pair of metal plates. At the peripheral edge portion of the vehicle interior board, the foamed polyurethane layer covers peripheral end portions of the metal plates and is formed flush with outer surfaces of the metal plates. This makes it possible to suppress oxidation of the peripheral end portions which are cutting surfaces of the metal plates. Further, bonding is good between the metal plates and the foamed polyurethane layer. Further, it is possible to prevent peeling of the metal plates, chipping of the foamed polyurethane layer, and the like. Furthermore, it is easy to demold a vehicle interior board.
