Indlela yokuphosa iwax elahlekileyo (okanye i-micro-fusion) yenye indlela yokubunjwa okulahlwayo apho imodeli yewax ilungiswa, ngokuqhelekileyo ngokuphosa uxinzelelo, kwaye ivuthiswe kwi-oven ukuze ivelise umngxuma othi emva koko uzaliswe yintsimbi.

Inyathelo lokuqala ke libandakanya ukuvelisa iimodeli ze-wax kunye nomngundo ngamnye wenza isiqwenga esinye.

Emva kokubeka imifuziselo kwiqela, elipheleleyo kunye nomjelo wokutya owenziwe ngewax, ugqunywe nge-ceramic paste elandelwa ngumxube wamanzi we-refractory othi emva koko uqiniswe (ukuphosa utyalo-mali).

Ubuninzi bezinto zokugubungela kufuneka zanele ukuchasana nobushushu kunye noxinzelelo xa isinyithi esityhidiweyo sifakwe.

Ukuba kuyimfuneko, ukugqunywa kweqela leemodeli kunokuphindwa kwakhona de ubuninzi bokugubungela buneempawu eziyimfuneko zokuxhathisa ukushisa.

Ngeli xesha isakhiwo sifakwe kwi-oven apho i-wax inyibilika kwaye iba, iguquguquke, ishiya imilo ilungele ukuzaliswa ngetsimbi.

Izinto ezenziwe ngale ndlela zifana kakhulu neyokuqala kwaye zichanekile ngokweenkcukacha.

Izibonelelo:

umgangatho ophezulu;

ukuguquguquka kwemveliso;

ukunciphisa ukunyamezela komlinganiselo;

kungenzeka ukusebenzisa i-alloys ezahlukeneyo (i-ferrous kunye ne-non-ferrous).
