Ekukhiqizweni kwesikhunta, isixhumanisi sokubumba insimbi esingenasici sokukhokhisa sisesimweni esibalulekile. I-China namazwe amaningi emhlabeni ajwayele ukusebenzisa izindlela zokuphonsa ngokunemba kwinqubo yokukhiqiza, kufaka phakathi ukuphonsa ama-gypsum, ukuphonsa imali, ukusakaza imali, ukuphonsa izinhlanzi okulahlekile, ukudluliselwa kwe-foam ukudluliselwa kwengqondo. Ukudluliselwa kwe-coation ukudluliselwa kwe-Pression Technology kuyindlela yokuphonsa esebenzisa indlela yokudlulisa ye-coating ukumboza ukuhlanganiswa okufanayo ekusakazeni, okungathuthukisa kakhulu ukunemba kokuphonsa kanye nokunciphisa ubulukhuni benkambiso. Qhathanisa nobuchwepheshe bokusebenzisa imali, le ndlela ayithambekele ekuphambukeni okuyisici; Ukunemba okubucayi kokukhokhwa kwale ndlela kuphakeme kakhulu kunalokho kwama-ceramic castings, kanti ama-castings alula ukuyihlanza.
Izinto ezibumbayo kumele zibe ne-shrinkage encane eqondile kanye ne-coefficial encane kakhulu yokunwebeka ezindaweni zokushisa ezithambile ukuze kufinyelelwe ukunemba okubucayi kwezinto zokubumba. Ngamandla amancane okushisa kanye nephuzu lokuncibilika elilinganiselwe, kulula ukudlula ku-wax ukwenza igobolondo lokubumba bese ukhipha i-wax egangeni lokubumba. Ukubumba kufanele kube nobulukhuni obunele namandla egumbini lokushisa lasekamelweni kanye nokuqina okuphezulu okushisayo emazingeni okushisa aphezulu. Ukuze ugweme ukuqhekeka okuhlukahlukene, ukulimala noma ukuklama okungaphezulu kokukhiqizwa kwangempela nasempilweni.
Ukusakazwa kwensimbi engenasici kunokunemba okubucayi, isibonelelo esincane semishini, ukonga isikhathi nezinto zensimbi. Ingasetshenziswa ukusakaza ama-superlloy castings, njenge-jet injini ama-blades, amaphrofayli ahambisanayo namagumbi okupholisa, okunzima ukusungulwa ngobuchwepheshe bezimali.
I-Alastin isebenzisa inqubo yokunemba ye-silica sol ephonsayo ukuqeda umkhiqizo owodwa omuhle ngemuva komunye. Ngaphezu kwe-hardware yacht, i-Alastin nayo ingafakwa kwizimboni ezijwayelekile ezifana nezokwelapha nokwakha.
