Abstract
The invention is directed to a process for the manufacture of a metallic molded structural part (1) for motor vehicle components such as door impact girders or bumpers with areas (2) with a higher ductility in relation to the rest of the structural component part. For this purpose, partial areas (2) of a plate (5) are initially heated to a temperature of 900.degree. C. within a period of less than 30 seconds. Subsequently, the thermal-treated plate (5') is shaped in a pressing tool (7) to form the molded structural part (1) and is heat-treated in the pressing tool (7).
