Ukulahlwa kwesanti kunye nokuphosa utyalo-mali ziinkqubo ezimbini eziphambili zokuphosaiziseko zangoku. Zombini ezi nkqubo zimbini zokuphosa zineempawu zazo zomntu ngamnye, iingenelo kunye nokungalungi. Iukugalela isantiisebenzisa isanti eluhlaza okanye isanti eyomileyo ukwenza umngundo phambi kokugalela. Phambi kokwenziwa komngundo, umthi, iplastiki okanye iipateni zentsimbi kufuneka ziveliswe kuqala ukuze kwenziwe umngxuma wokungunda kwesanti. Isanti eluhlaza kunye nesanti eyomileyo zinokuphinda zisetyenziswe emva kokuphonswa nokushukunyiswa.
Ngexeshautyalo mali, imilo okanye ikopi yenziwa (ngokuqhelekileyo iphuma kwiwax) ize 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. Amalungu eCast anenkangeleko eyodwa kuwo, ahluke kakhuluiindawo ezenziwe ngoomatshini. 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. Ekugalweni kwesanti, ipateni ifuna ukutsalwa ngaphandle kwesanti emva kokuba ipakishiwe, ngelixa utyalo-mali olusakhasayo ipateni yenziwa ngumphunga ngenxa yobushushu. 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.
