ABSTRACT:
A method of manufacturing an entire piston, piston heads for example, especially intended for internal-combustion engines, wherein in an initial manufacturing step a blank that will eventually constitute the piston is preliminarily forged along a prescribed axis, shaping appropriate contours, and wherein in at least one subsequent manufacturing step the preliminarily shaped piston is finally forged along at least one other axis, creating additional contours.
