Abstract: A method for manufacturing a free-form optical component in an injection unit and a painting tool including at least one cavity. Initially, the manufacturing of the free-form optical component as a cover plate takes place by injection molding or injection embossing of a transparent plastic material in the injection unit. The introduction then takes place of a laser-transparent, opaque paint material into a one-sided gap between the cover plate and a boundary of the first cavity of the painting tool. The treated cover plate is turned into a second cavity of the painting tool and the introduction of a self-healing paint layer into the second cavity takes place in such a way that a gap surrounding the treated cover plate is completely filled by the self-healing plastic material and surrounds the free-form optical component.

Abstract: A method and a system for producing a luminescent 3D radar-module cover for a radiator grille of a motor vehicle. A three-dimensional structure including an optical conductor is produced from a light-dispersing first plastic material in separate method steps using a first injection mold. The three-dimensional structure is metallized and metal-coated. A subsequent separation of the gating takes place. A cover element is produced from a second plastic material using a second injection mold, which at least partially covers the metallized three-dimensional structure in a planar manner in a position of use. A contour of the three-dimensional structure is left free. The gating is subsequently severed. The three-dimensional structure is metallized together with the cover element disposed thereon and is embedded in a third plastic material with the aid of a third injection mold while molding a mount for a radar module and fastening points on the molded component.

Abstract: A method for producing a pendulum arrangement of a pendulum laser device includes producing a universal joint of a pendulum of the pendulum arrangement by forming two orthogonal, at least partially micro-structured shafts via plastic injection moulding and positioning at least two bearing shells on the at least partially micro-structured regions of at least one shaft of the universal joint. The method further includes producing an optic carrier of the pendulum of the pendulum arrangement as a single piece with the bearing shells by overmoulding at least two bearing shells surrounding a shaft of the universal joint via plastic injection moulding. The optic carrier is connected to the universal joint such that it is configured to rotate about the one shaft.

Abstract: The invention relates to a housing (10) for an electrical machine (50) and to an electrical machine (50) having such a housing (10). The housing (10) comprises an inner wall (12) and an outer wall (14), with a hollow space (16) therebetween for cooling the electrical machine (50) with a fluid. The housing (10) further has a sealing device (24, 26) on a front face (22, 23) of the housing (10). The housing is particularly characterised in that the sealing device (24, 26) comprises an annular sealing element (28) mounted between the inner wall (12) and the outer wall (14) so as to seal the front face, and in that the sealing device (24, 26) comprises a deflection ridge (30) which projects from the sealing element (28) in the axial direction of the housing (10) and is at least partially arranged between the walls (12, 14), the deflection ridge (30) being designed to lead a cooling fluid in the hollow space (16). A compact, economical and fluid-tight housing (10) can thus be advantageously provided.

Abstract: An image recording system, for example of a motor vehicle, includes a carrier plate, an optics holder with a through hole of which one side is closed by a surface of the carrier plate, and an image recorder situated on the carrier plate surface, a needle channel that extends through the optics holder from the through hole to an outer side of the optics holder and that is suitable for, after the optics holder has been manufactured, injection molding of an encapsulation that forms an optical lens of the image recorder without having to protect a surface of the encapsulation during the manufacturing of the optics holder. Manufacturing of a microstructured protective lens directly after manufacturing of the optics holder on the same injection mold is thus enabled.

A base intermediate space is formed between the base of the outer housing and the base of the inner housing. A bearing for the rotor shaft is provided in the base of the inner housing and is heated by heat from the electric machine. The spiral-shaped cooling channel for cooling the bearing for the rotor shaft is not guided into the base intermediate space.
