During final stamping, occurrence of structure and part shape defects is prevented due to flowing of metal in different directions. At final stamping stage blind piercing of openings is effectuated with following ultimate piercing. Central cavity may be made blind or through. EFFECT: increased efficiency, simplified construction and improved quality of parts. 3 cl, 15 dwg
