Ekwenzeni isikhunta, isixhumanisi sokubumba ngokunemba kwensimbi engagqwali sisesimweni esibalulekile. IShayina namazwe amaningi emhlabeni bavame ukusebenzisa izindlela zokubumba ngokunemba enqubweni yokukhiqiza, okuhlanganisa ukubumba nge-gypsum, ukubumba nge-ceramic, ukubumba ngokutshalwa kwezimali, ukubumba nge-foam elahlekile, ukubumba nge-thermosetting resin sand mold, ukubumba ngokunemba kokudlulisa ukumboza. Ubuchwepheshe bokubumba ngokunemba kokudlulisa ukumboza kuyindlela yokubumba esebenzisa indlela yokudlulisa ukumboza ukumboza ukumboza okufanayo ekubumbeni, okungathuthukisa kakhulu ukunemba kobukhulu bokubumba futhi kunciphise ubulukhuni bomphezulu wokubumba. Uma kuqhathaniswa nobuchwepheshe bokubumba ngokutshalwa kwezimali, le ndlela ayithambekele kakhulu ekuphambukeni kobukhulu; Ukunemba kobukhulu bokubumba okukhiqizwa yile ndlela kuphakeme kakhulu kunokwama-ceramic castings, futhi ama-castings kulula ukuwahlanza.
Izinto zokubumba kumele zibe nokuncipha okuncane okuqondile kanye ne-coefficient encane kakhulu yokwandisa ekushiseni okuthambile ukuze kufezwe ukunemba kobukhulu bezinto zokubumba. Njengoba zinamandla okushisa amancane kanye nephuzu lokuncibilika elimaphakathi, kulula ukudlula ku-wax ukuze wenze igobolondo lokubumba bese ukhipha i-wax egobolondo lokubumba. I-mold kufanele ibe nobunzima obanele namandla ekushiseni kwegumbi kanye nokuqina okuphezulu kokushisa ekushiseni okuphezulu kancane. Ukuze ugweme ukuqhekeka okuhlukahlukene, ukulimala noma imihuzuko ebusweni ekukhiqizweni kwangempela nasekuphileni.
Ukuphonswa kwensimbi engagqwali ngokunemba kunokunemba okuthile okunezilinganiso, isabelo esincane somshini wokugaya, konga isikhathi sokucubungula kanye nezinto zensimbi. Kungasetshenziswa ukuphonswa kwe-superalloy castings, njenge-jet engine blades, amaphrofayili alula kanye namakamelo okupholisa, okunzima ukwakheka ngobuchwepheshe bomshini wokugaya.
I-Alastin isebenzisa i-silica sol process precision casting ukuze iqedele umkhiqizo omuhle kakhulu ngemva komunye. Ngaphezu kwehadiwe ye-yacht, i-alastin ingasetshenziswa nasezimbonini ezisezingeni eliphezulu njengokwelashwa kwezokwelapha kanye nokwakha.
