The invention relates to a seating frame for a vehicle seat, the frame comprising a back frame component for supporting a back rest, wherein the back frame component includes a plurality of interconnected reinforcing ribs that form a single unit, and wherein the seating frame is a one-piece injection-molded part made of plastic material. The invention also relates to a process of making such a seating frame. Furthermore, the invention relates to a vehicle seat comprising such a seating frame, and a vehicle comprising such a vehicle seat or such a seating frame.

A method for manufacturing an impeller with a number of impeller blades and a cover disc covering the impeller blades. Plastic is injected into an injection mold using a cascade injection molding process to form the impeller. The injection mold has a number of shut-off nozzles to feed the plastic at various joint positions and different opening times. The number of shut-off nozzles is determined as a function of the number of impeller blades.

A method and a device for producing fibre-reinforced plastic mouldings, using coated fibre strands. For the coating of the fibre strands, an air flow of ionised air is produced and guided through a Venturi nozzle. Powder from a storage container is taken by means of a screw conveyor and supplied to the Venturi nozzle, a flow of a powder-air mixture being present or forming behind the Venturi nozzle in the direction of flow. This stream is introduced into a chamber and fibre strands that are earthed or ionised unlike the powder are passed through the chamber and through the powder-air mixture flowing through the chamber, powder particles being deposited on the fibre strands. The fibre strands guided out of the chamber therefore have a coating, and the fibre strands coated in this way are supplied to a plasticising device of an injection moulding machine or an extrusion machine.

The present invention relates to door modules comprising at least one single-layer, continuous fiber-reinforced semifinished fiber matrix product which is obtained by impregnating semifinished fiber products with at least one thermoplastic, and to the use thereof in vehicles or in buildings.

An apparatus for producing a fiber-reinforced injection molded component includes an injection mold half with a mold cavity and a receiving chamber open to the mold cavity. A band section of a fiber-reinforced plastics band is fed into the receiving chamber through a feed channel and a first clamping device arranged in an initial region of the receiving chamber and a second clamping device arranged in an end region of the receiving chamber clamp the fiber-reinforced plastics band section within the receiving chamber. A first cut-through device arranged in the initial region of the receiving chamber and a second cut-through device arranged in the end region of the receiving chamber cut the band section such that an injection molded component formed in the cavity of the mold includes the cut fiber-reinforced plastics band section and a fiber-reinforced injection molded component is provided.

Provided is a method for producing a gear including an intermediate product forming process of solidifying a fluid material to form a gear intermediate product, and a tooth forming process of cutting the gear intermediate product to form teeth.

A component for a vehicle interior is disclosed. The component may be formed from a composition comprising polyketone resin in a range of less than about 40 percent by weight, compatible resin, copolymer, compatibilizer and reinforcing material. An effect on a surface of the component is provided by the composition as a result of crystallinity and half-time of crystallization. The composition may provide crystallinity above about 15 percent and half-time crystallization above about 42 seconds. The component may provide crystallinity in a range of between about 17 to 26 percent. The effect provided by crystallinity and crystallization rate of the composition may comprise a substantially consistent visual effect at the surface of the component. The composition may comprise a polyketone composite material. A method of forming the component providing the crystallinity for the visual surface effect from the composition in a tool as a molded part is also disclosed.

Recycled carbon fibers are processed by rotational tumbling in a mixture with binder material to prepare fiber-containing particles having a dual-tapered shape and general alignment of fibers with a longitudinal direction of the particles. Bulk products including such fiber-containing particles are compounded with polymer and pelletized to prepare fiber-reinforced composite pellets, which are useful for applications such as injection molding to prepare molded products of carbon fiber-reinforced composite material with recycled carbon fibers.

A method for preparing a composite material that includes the steps of: (i) heat treating natural lignocellulosic fibers at a temperature of 130 to 320° C. for 2 minutes to 24 hours in an atmosphere oxygen-deficient in and in the presence of water vapor, and (ii) mixing the heat treated natural lignocellulosic fibers with at least one thermoplastic polymer in the molten state and whose melting point is less than or equal to 230° C. The method is useful for producing vehicle parts from a composite material having natural lignocellulosic fibers with reduced volatile organic compound odor emissions.

A method is described for producing fibre-reinforced plastic moulded parts, wherein endless fibre strands are fed by a fibre braking device and/or cut fibres via a gravimetric metering device, and a plastic material to be melted, by a volumetric metering device are fed to a single-screw plasticizing unit. Plastic material which is molten and is mixed with fibre material is injected into a moulding tool by an injection stroke of the plasticizing screw. According to the application, the ACTUAL mass flow of the plastic material is calculated from the ACTUAL volume flow of the plastic material and from the ACTUAL mass flow of the fibre material. The ACTUAL mass flow of the plastic material is compared to a TARGET mass flow of the plastic material, and the rotation speed n.sub.d of the rotary drive of the metering element of the metering device is adapted.
