I-Rough Ii-DEA yeUlwandisoi-rusikuvuliweMachine
Umatshini wokukhupha uqulathe ezi zinto zilandelayo: i-hopper, i-feeding screw, izinto zokufudumeza kunye ne-gear pump. Izinto zifakwa kumatshini kwi-hopper. I-feeding screw ejikelezayo rhoqo, eqhutywa yi-motor kunye ne-gearbox, ihambisa izinto ecaleni kwe-barrel nakwi-die. Izinto zokufudumeza ecaleni kwe-barrel zigcina amaqondo obushushu alawulwayo ukuze zithambise kwaye zinyibilikise izinto ze-polymer. Emva kokuphuma kwi-die, izinto ezinyibilikisiweyo zingena kwi-mold ene-cavity enye okanye ezingaphezulu, apho iphola kwaye iqine ibe yimo oyifunayo. Kwezinye iinkqubo, i-gear pump ibekwa phakathi kwe-barrel kunye ne-die ukuqinisekisa uxinzelelo oluqhubekayo kwizinto eziphumayo.
