A method is provided for producing a polymeric vehicle component, particularly an outer component in the form of a bumper, spoiler, sill, mud guard or the like. A polymeric shell part is first produced. Then, via a first automated process step, at least one aperture in the shell part is produced, which then defines an inner face in the shell part. Further, in a separate, second automatic process step, a radial embossing (R) is produced at a peripheral edge formed by an outer shell part surface and the inner face, in that a die with a contour corresponding to the desired radius (r) of the radial embossing (R) is pressed along the inner face against the peripheral edge. The die travels at least once along the complete peripheral edge, thus travelling along a path corresponding to the contour of the edge, such that all the peripheral edge is provided with the desired radial embossing.

Method for rounding edges of polymer motor vehicle components

Apparatus has a receptacle () for two workpiece parts () which extend two-dimensionally in X and Y directions and which are to be joined along a weld. The apparatus includes a laser beam source () comprising a plurality of individually controllable laser beam emitters () which collectively form a line array which is oriented in X direction, a transporting device () for transporting the laser beam source () relative to the receptacle () in Y direction, and a homogenizer () arranged downstream of the laser beam source () in the radiating direction. The homogenizer () has a carrier () in which is provided at least one reflection channel () with a channel cross section (QS) which is adapted to the course of the weld and a channel width (b) which is adapted to the width of the weld.
