vormpressimine e väljasuruv stantsimine (viiakse tavaliselt läbi külmalt) kombineeritud mehaanilise toime järgi, mispuhul osa tooriku metallist voolab templi liikumise suunas, osa vastupidiselt (vt vormpressimine; vrd pärivormpressimine, vastuvormpressimine), the process of impact extrusion (commonly cold working) where metal is forced to flow both in forward and backward directions to the ram being used to apply pressure (see: impact extrusion; compare: forward impact extrusion, backward impact extrusion)
