Steel Sand Castings

Iisanti zentsimbi ziindawo zokugalela zentsimbi eziveliswa yinkqubo yokugalela isanti. Iintsimbi zentsimbi yindibaniselwano yenkqubo yokubumba kunye nesinyithi semathiriyeli yentsimbi. Abakwazi nje ukuba nesakhiwo esiyinkimbinkimbi ekunzima ukuyifumana ngezinye iinkqubo zokwenza, kodwa nokugcina iimpawu ezikhethekileyo zetsimbi, ngoko ke iindawo zokuphosa intsimbi zinendawo ephakamileyo ebalulekileyo kwizinto zokwakha zobunjineli. Kuninzi lweziseko, ukujulwa kwentsimbi kuveliswa ikakhulu ngezi nkqubo zininzi zokuphosa: ukuphosa utyalo-mali, ukuphosa ugwebu olulahlekileyo, ukugalelwa kwevacuum, ukuphosa isanti kunye nentlabathi egqunywe intlaka.
Intsimbi yokuphosa inokohlulwa ibe yintsimbi yealloyi kwaye iphose intsimbi yekhabhoni ngokwemichiza yayo, kwaye inokwahlulwa ibe yintsimbi yesixhobo, intsimbi ekhethekileyo, ubunjineli kunye nolwakhiwo kunye nokuphosa intsimbi yentsimbi ngokweempawu zayo. Intsimbi yokuphosa ingxubevange inokwahlulwa ibe yintsimbi ephantsi yealloyi (izinto ezipheleleyo zealloy zingaphantsi okanye zilingana ne-5%), intsimbi yealloyi (izinto ezipheleleyo ze-alloy ziyi-5% ukuya kwi-10%) kunye nentsimbi ephezulu yealloy (i-alloy iyonke). izinto ezinkulu kuno okanye zilingana ne-10%).
