Abstract
A method for producing plastic moldings with a distinct grain/three-dimensional surface structure by grain-imparting negative thermoforming. The plastic molding is subjected to a preheating, and the molding is then pressed into/onto a negative mold that is formed with the negative of the three-dimensional surface structure to be applied. Those portions of the plastic molding that face away from the grain side are subjected to electron beam crosslinking before or during the preheating and the grain-imparting negative thermoforming.
