combined backward and forward extrusion, combined forward and backward extrusion, indirect-direct extrusion
külmvormpressimine e väljasuruv külmstantsimine kombineeritud mehaanilise toime järgi, mispuhul osa tooriku metallist voolab templi liikumise suunas, osa vastupidiselt (vt külmvormpressimine; vrd pärivormpressimine, vastuvormpressimine), the process of impact extrusion (cold extrusion) 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 extrusion/forward impact extrusion, backward extrusion/backward impact extrusion)
