Ukulahlwa kogwebu olulahlekileyo luhlobo oluncinane lokugalelwa kwesanti olusebenzisa uncedo lwesanti eyomileyo ukwenza ukubumba okutyhidiweyo. Ukuphosa amagwebu alahlekileyo kubhekiselele kwiindawo zokuphosa eziveliswe yinkqubo yokuphosa ugwebu elahlekileyo. Isinyithi esinentsimbi kunye ne-non-ferrous, kubandakanywa intsimbi engwevu, i-ductile iron, intsimbi ethambileyo, i-carbon steel, i-alloy steel kunye ne-aluminium alloys inokuphoswa ngokuphosa ugwebu olulahlekileyo.Ukuphosa amagwebu alahlekileyo, I-LFC ngokufutshane, ebizwa ngokuba yi-Full Mold Casting, luhlobo lwe-Evaporative Pattern Casting (EPC) kunye nenkqubo yokuphosa isanti esomileyo. I-EPC ngamanye amaxesha inokuba mfutshane kwi-Expendable Pattern Casting kuba iipateni zogwebu ezilahlekileyo zingasetyenziswa kube kanye kuphela. Emva kokuba iipateni zamagwebu zigqitywe ngoomatshini abakhethekileyo, emva koko iipateni zeplastiki ezinogwebu zigqunywe nge-refractory coating ukuze zenze iqokobhe elomeleleyo lokumelana nentsimbi etyhidiweyo. Iipateni ze-foam ezinamaqokobhe zifakwa kwibhokisi yesanti, kwaye uyigcwalise ngesanti eyomileyo ejikelezileyo. Ngexesha lokuthululelwa, isinyithi esinyibilikisiweyo esiphezulu sobushushu senza i-foam iphethini i-pyrolyzed kwaye "inyamalale" kwaye ithatha indawo yokuphuma yeepatheni, kwaye ekugqibeleni i-castings efunwayo egqityiweyo ifunyenwe.
