METHOD AND PRODUCTION LINE USED FOR THE PRODUCTION OF A MONOLITHIC PISTON FOR COMBUSTION ENGINES

摘要

In a forging process to manufacture a semi-finished automotive piston (R), the piston side outer face (KS) is formed by reverse extrusion. Further, the piston head has a circular groove (H) formed by a forging tool applied after completion of the reverse extrusion process. The piston is finished by a machining process. Further claimed is a commensurate piston production line and a piston.
