Method for rounding edges of polymer motor vehicle components

Abstract

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.
