Ukufunxa ivacuum yinkqubo esetyenziselwa ukwenza amalungu adibeneyo.Kule nkqubo, i-fiber preform eyomileyo (njenge-fiberglass okanye i-carbon fiber) ifakwe kwi-mold, kwaye i-vacuum isetyenziselwa ukususa umoya kwi-mold cavity.I-resin ke ifakwe kwi-mold phantsi koxinzelelo lwe-vacuum, ivumela ukuba ifake imicu ngokulinganayo.Uxinzelelo lwe-vacuum lunceda ukuqinisekisa ukungena ngokupheleleyo kwe-resin kunye nokunciphisa i-voids kwinxalenye yokugqibela.Emva kokuba inxalenye ifakwe ngokupheleleyo, iphiliswa phantsi kweqondo lokushisa elilawulwayo kunye neemeko zoxinzelelo.
