I-alloy steel castings ngenkqubo yokuphosa i-vacuum idlala indima ebalulekileyo kwiindawo ezahlukeneyo zoshishino. Inkqubo yokubumba i-vacuum-sealed casting, i-V-process casting short, isetyenziselwa ngokubanzi ukwenza intsimbi kunye neentsimbi zentsimbi ezinodonga oluncinci, ukuchaneka okuphezulu kunye nomphezulu ogudileyo. Nangona kunjalo, inkqubo yokuphosa i-vacuum ayinakusetyenziselwa ukugalela iintsimbi zetsimbi ezinobunzima obuncinane kakhulu bodonga, kuba ulwelo lwetsimbi oluzaliswa kumgodi wokungunda luxhomekeke kuphela kwintloko yoxinzelelo lwe-static kwinkqubo ye-V. Ngaphezu koko, inkqubo ye-V ayikwazi ukuvelisa i-castings efuna ukuchaneka komgangatho ophezulu kakhulu ngenxa yokuthintelwa kwamandla okuxinwa kwesikhunta.
