In utyalo mali,imilo okanye ikopi yenziwe (idla ngokuphuma kwiwax) kwaye ifakwe ngaphakathi kwicylinder yentsimbi ebizwa ngokuba yiflask. Udaka olumanzi lugalelwa kwi-cylinder ejikeleze imilo ye-wax. Emva kokuba udaka luqinile, isilinda esinepateni yewax kunye nodaka lufakwa kwi-oven kwaye lufudunyezwe de umthwebeba ube ngumphunga ngokupheleleyo. Emva kokuba i-wax itshise ngokupheleleyo (i-de-waxing), i-flask iyasuswa kwi-oven, kwaye isinyithi esityhidiweyo (ngokuqhelekileyo isinyithi se-alloy, insimbi engenasici, ubhedu ... njl. Xa intsimbi sele ipholile yaza yaqina, udaka luyancothuka, kuze kutyhilwe ukubunjwa kwentsimbi.
Ukuphosa kuluncedo kakhulu ekudaleni izinto eziqingqiweyo okanye iimilo zobunjineli ezinejometri entsonkothileyo kwintsimbi.Iindawo zokuphosa zinenkangeleko eyodwa kuzo, zahluke kakhulu kumalungu oomatshini. Ezinye iimilo ezinokuba nzima ukwenza umatshini ziphosa ngokulula. Kukwakho nenkcitho encinci yezinto eziphathekayo kwiimilo ezininzi, kuba ngokungafaniyo nomatshini, ukuphosa akuyona inkqubo yokuthabatha. Nangona kunjalo, ukuchaneka okufezekiswayo ngokuphosa akulunganga njengoomatshini.
Kufuneka ukhethe nini ukuCasa uTyalo-mali kwaye kufuneka ukhethe nini iSand Casting?
Enye inzuzo enkulu yokuphosa utyalo-mali kukuba inokuvumela ii-undercuts kwipatheni, ngelixa ukuchithwa kwesanti akwenzi. Kwiukugalela isanti, ipateni kufuneka itsalwe ngaphandle kwesanti emva kokuba ipakishwe, kanti kwi-investment casting ipateni ikhutshwe ngubushushu. Ukwenziwa komgongxo kunye namacandelo amancinci nawo anokwenziwa ngokulula ngakumbi ngotyalo-mali, kwaye ukugqitywa okungcono komphezulu kuyafezekiswa ngokubanzi. Kwelinye icala, utyalo-mali yinkqubo efike ngexesha kwaye ibiza kakhulu, kwaye inokuba nezinga lempumelelo elisezantsi kunesanti esenziwayo kuba kukho amanyathelo amaninzi kwinkqubo kunye namathuba amaninzi okuba izinto zingahambi kakuhle.
