Ukugalelwa kwesantiyinkqubo yesiqhelo kodwa neyanamhlanje. Isebenzisa isanti eluhlaza (isanti emanzi) okanye isanti eyomileyo ukwenza iinkqubo zokubumba. Ukugalelwa kwesanti eluhlaza yeyona nkqubo indala isetyenziswa kwimbali. Xa usenza isikhunta, iipatheni ezenziwe ngomthi okanye isinyithi kufuneka ziveliswe ukuze zenze umgodi ongenanto. Isinyithi esinyibilikisiweyo sigalela emngxunyeni ukwenza icastings emva kokupholisa kunye nokuqina. Ukwenziwa kwesanti kubiza ngaphantsi kunezinye iinkqubo zokuphosa zombini kuphuhliso lokungunda kunye neyunithi yokuphosa inxalenye. Ukuphosa isanti, kusoloko kuthetha ukuphosa kwesanti eluhlaza (ukuba akukho nkcazo ekhethekileyo). Nangona kunjalo, kule mihla, ezinye iinkqubo zokuphosa nazo zisebenzisa isanti ukwenza umngundo. Banamagama abo, njengayeiqokobhe ngundo ukuphosa, i-furan resin egqunywe isanti egayiweyo (akukho ntlobo yokubhaka),ukuphosa amagwebukunye ne-vacuum casting.
