Abstract (en)
[origin: WO2011072656A1] The present invention relates to a method for producing a piston (10) from an upper piston part (11, 111, 211) and a lower piston part (15). A strip- or plate-shaped semifinished product (22) made of a metal material is provided, from which an annular upper piston part (11, 111, 211) or an annular blank (25) is stamped out, which blank is finished to form an upper piston part (11, 111, 211), wherein the upper piston part (11, 111, 211) is connected to a lower piston part (15) to form a piston (10).
