Abstract

A polymer workpiece is described. The workpiece has an upper main surface, a lower main surface, an injection-mold separating surface and a flow attack edge surface. The flow attack edge surface is formed in the region between the injection-mold separating surface and the lower main surface as a planar surface with an angle α with respect to the injection-mold separating surface of 20° to 70°, and/or deviates by an amount a from 0.0 mm to 0.5 mm from the planar surface.
