Umngundo we-ingot sisikhongozeli okanye umngundo osetyenziswa kwinkqubo yokubunjwa ukubumba kunye nokuqinisa isinyithi esityhidiweyo kwiingots. Ngokuqhelekileyo zenziwe ngezinto ezizinzileyo ezifana nentsimbi, intsimbi, okanye igraphite, kwaye yenzelwe ukujamelana namaqondo okushisa aphezulu kunye noxinzelelo olubandakanyekayo kwinkqubo yokuphosa.

I-ingot mold ibekwe kwindawo elawulwayo apho isinyithi esityhidiweyo sigalelwa kuyo. I-mold idla ngokuxhotyiswa ngamajelo okanye abagijimi abavumela ukuba isinyithi sigeleze kwisimo esifunwayo. Njengoko intsimbi iphola kwaye iqina ngaphakathi kokungunda, ithatha ubume bomgodi wokungunda, okukhokelela kwi-ingot eqinile yobukhulu obuthile kunye nokumila.

Iimold ze-Ingot ziza ngobukhulu obahlukeneyo kunye neemilo, ngokuxhomekeke kwiimfuno zenkqubo yokuphosa kunye nemilinganiselo ye-ingot efunwayo. Ziyakwazi ukusuka kwi-rectangular elula okanye i-cylindrical molds ukuya kwi-design complex ene-cavities ezininzi.

Emva kokuba isinyithi siqinile, i-ingot mold iyasuswa, kwaye i-ingot eqiniweyo ikhutshwe ukuze iqhubekele phambili okanye igcinwe. Kumashishini okuvelisa kunye nesinyithi, ukubumba kwe-ingot kudlala indima ebalulekileyo ekuveliseni i-ingots zetsimbi ezisemgangathweni ezinokusetyenziselwa iinjongo ezahlukeneyo, ezifana nokuqhubekela phambili, ukuxutywa, okanye ukunyibilika kwakhona.
