Zininzi iindlela zokuphosa, ezihluliweyo zahlulahlulwe zazise:
① Ukuphoswa kwesanti esiqhelekileyo, kubandakanya isanti emanzi, isanti eyomileyo kunye nesanti ye-chemic.
Ukuphoswa kwemodeli ekhethekileyo, ngokwemifanekiso yokumodareyitha, kunokwahlulwa kuba yinto ekhethekileyo yesanda semijelo (njengokuphoswa kwemodeli, ukuphosa i-shorling, ukuphoswa kwentsimbi, ukuphoswa kwentsimbi, njl. Njl.).
Inkqubo yokuphosa ihlala ibandakanya:
① Ukulungiselela ukuphosa iimbumbulu (izikhongozeli ezenza isinyithi mayibe seziphongo eziqinileyo). Ngokwezixhobo ezisetyenzisiweyo, ukuphosa imbumbulu kunokwahlulwa kuba yi-Sunds, ukubumba kwentsimbi, ubumbano be-ceramic, ubumbano lwe-ceramic, i-phy njl.
② Ukunyibilika kunye nokugalelwa iintsimbi zentsimbi, zakhupha izinyithi (i-alloys) ikakhulu ziquka i-iron, intsimbi yentsimbi yaza yaphosa izabelo ezingengobunjiweyo;
③ Ukuphosa unyango kunye nokuhlola, ukuphosa unyango kubandakanya ukususwa kwento yangaphandle kwi-corers kunye nokugxotha, ukususwa komgangatho, ukuvuselelwa, i-aust-rust kunye nomatshini onxaxhileyo.
Izibonelelo

(3) Unokuphosa nayiphi na intonga yensimbi kunye ne-alloy.

Kuba ukulahla kunezibonelelo ezingentla, kusetyenziswa ngokubanzi kwimveliso engenanto yamalungu.
Inkqubo yokuphosa inokwahlulwa ibe ngamacandelo amathathu asisiseko, egama lisithi ukulungiselela intsimbi, ukulungiselela ukulungiswa kwe-mold kunye nokuphosa ukuqhuba. Isinyithi sibhekisa kwizinto zentsimbi ezisetyenziselwa ukulahla izigqibo kwimveliso. Ngu-Allo olwenziwe ngento yentsimbi njengeyona nto iphambili kunye nezinye izinyithi okanye izinto ezingarhafiyo zongezwa. Ngokufanelekileyo oko kubizwa ngokuba yi-Cally Alloy, ikakhulu kubandakanya i-iron yentsimbi, intsimbi yaphosa izabelo ezingengabi.
