Kwimveliso yesikhunta, ikhonkco lokubumba elichanekileyo lentsimbi engagqwaliyo likwindawo ephambili. ITshayina kunye namazwe amaninzi ehlabathini adla ngokusebenzisa iindlela zokubumba ezichanekileyo kwinkqubo yemveliso, kubandakanya ukubumba ngegypsum, ukubumba ngeceramic, ukubumba ngotyalo-mali, ukubumba ngefoam elahlekileyo, ukubumba nge-thermosetting resin sand mold, ukubumba nge-coating transfer precision casting. Iteknoloji yokubumba nge-coating precision casting yindlela yokubumba esebenzisa indlela yokuguqula ukugquma isikhunta esifanayo kwisikhunta, enokuphucula kakhulu ukuchaneka kobukhulu besikhunta kwaye inciphise uburhabaxa bomphezulu wesikhunta. Xa kuthelekiswa neteknoloji yokubumba ngotyalo-mali, le ndlela ayithambekeli kakhulu ekuphambukeni kobukhulu; Ukuchaneka kobukhulu besikhunta esenziwe yile ndlela kuphezulu kakhulu kunoko kwesikhunta ngeceramic, kwaye ukubumba kulula ukukucoca.
Izinto zokubumba kufuneka zibe nokuncipha okuncinci komgca kunye ne-coefficient encinci yokwandisa kubushushu bokuthambisa ukuze kufezekiswe ukuchaneka kobukhulu bezinto zokubumba. Ngomthamo omncinci wobushushu kunye nendawo yokunyibilika ephakathi, kulula ukudlula kwi-wax ukwenza igobolondo lokubumba kunye nokukhupha i-wax kwigobolondo lokubumba. I-mold kufuneka ibe nobunzima obaneleyo kunye namandla kubushushu begumbi kunye nokuzinza okuphezulu kobushushu kubushushu obuphezulu kancinci. Ukuze kuthintelwe ukwaphuka okwahlukeneyo, umonakalo okanye imikrwelo yomphezulu kwimveliso yokwenyani kunye nobomi.
Ukuphoswa kwesinyithi esingenasici kunomlinganiselo othile wokuchaneka, isibonelelo esincinci somatshini wokugaya, ukonga ixesha lokucubungula kunye nezixhobo zesinyithi. Ingasetyenziselwa ukuphoswa kwe-superalloy castings, njengee-jet engine blades, iiprofayili ezilungelelanisiweyo kunye namagumbi okupholisa, ekunzima ukwenziwa yiteknoloji yokugaya.
I-Alastin isebenzisa i-silica sol process precision casting ukuze igqibezele imveliso enye emva kwenye. Ukongeza kwizixhobo ze-yacht, i-alastin ingasetyenziswa nakwimizi-mveliso ekumgangatho ophezulu efana nonyango kunye nolwakhiwo.
