Abstract: A support frame for components of a vehicle lighting device, especially for a housing or for a light module. The support frame features a sandwich structure of at least two metallic sheet members in parallel arrangement and at least one intermediate plastic joint member, which features form-locking joints with the sheet members.

Abstract: A tool for welding a light pane to a housing of a motor vehicle light, the tool comprising a base body and at least one heating element arranged on the base body, wherein the heating element is displaceable relative to the base body between an idle position and a welding position.

Abstract: A method for producing a screw connection having a screw that is set in rotational motion with a screwdriving head of a screwdriving tool. The screwdriving head has a motor drive for creating the rotational motion of a screw receptacle of the screwdriving head. The screw is driven into at least one mating part of the screw connection in a rapid speed. A torque is detected with which the screw is driven. The rapid speed with a higher rotational speed is changed to a creep speed with a lower rotational speed at a changeover time. The changeover time is determined as a function of the detected torque during screwdriving at rapid speed. The screw is further driven at the creep speed until a head contact time when a head of the screw makes contact on the mating part.

Abstract: A method for producing an adhesive connection between a first component and a second component, wherein the first component has at least one cavity and the second component has at least one pin, The cavity is at least partially filled with an adhesive, and the components are aligned relative to one another such that at least sections of the pin project into the adhesive inside the cavity. A heating that is limited to the adhesive is carried out by means of a targeted, local introduction of heat into the adhesive in order to cure the adhesive.

Abstract: A lighting device for a vehicle, comprising a housing, an illuminant arranged in the housing and comprising a light panel for the passage of light generable by the illuminant, wherein a frame is provided, which is molded onto the light panel at least on the edge side in an at least sectionally circumferential fashion using a plastic injection molding process, and wherein the frame is joined to a connection portion of the housing by means of a plastic welded seam. The invention further relates to a method for producing a lighting device.

Abstract: A method for manufacturing a multicomponent injection-molded part is provided. A first plastic component is manufactured with the aid of a first injection molding step, and a second plastic component is at least partially injection-molded onto or over the first plastic component with the aid of a second injection molding step, so that a material composite is formed with the two plastic components. At least one part of an edge area along the parting line between the two plastic components is heated by means of a heat source for the purpose of sealing the two plastic components to each other in the edge area.
