Abstract
A method of manufacturing molding members, for instance for automobiles, wherein an elongate shaped body is prepared from synthetic resin material either by an extrusion process, or by an injection process and is subjected to a controlled heating so as to soften the interior resin material while preserving the hardness of the outer surface portion. A cutter blade is advanced into the shaped body while it is subjected to the controlled heating, whereby the outer surface portion is urged and deformed inwardly to form a smooth end surface in continuous connection with remaining outer surface of the molding member.
