Ukutshalwa kwezimali kubizwa nangokuthi ukulahleka kwe-wax casting noma ukucacisa ngokunemba, okuyindlela yokwakha insimbi yokukhiqiza izingxenye ezinokubekezelelana okuqinile, izimbotshana eziyinkimbinkimbi zangaphakathi nobukhulu obuqondile.
Ukulingiswa kotshalo-mali kuyinqubo yokukhiqiza lapho iphethini ye-wax ifakwe okokusebenza kwe-ceramic okukhanyayo. Lapho okokusebenza kwe-ceramic kuqinisiwe i-geometry yayo yangaphakathi ithatha isimo sokuphonsa. I-wax iyancibilika futhi insimbi encibilikisiwe ithululelwa emgodini lapho iphethini le-wax lalikhona. Insimbi iyaqina ngaphakathi kwesikhunta se-ceramic bese kuphuma insimbi. Le ndlela yokukhiqiza yaziwa nangokuthi inqubo elahlekile ye-wax. Ukusatshalaliswa kotshalo-mali kwasungulwa emuva ezinkulungwaneni zeminyaka edlule futhi kungabheka izimpande zawo emuva eGibhithe lasendulo naseChina.
Izinqubo eziyinhloko zinjengokulandelayo:
Ukudalwa kwamaphethini - Amaphethini we-wax ajwayelekile umjovo obunjwe ensimbi yensimbi futhi akhiwa njengocezu olulodwa. Ama-cores angasetshenziswa ukwakha noma yiziphi izici zangaphakathi kuphethini. Amaningana ala maphethini anamathiselwe ku-wax gating system emaphakathi (i-sprue, abagijimi, nama-risers), ukwakha umhlangano ofana nesihlahla. Uhlelo lwesango lwakha imigudu lapho insimbi encibilikisiwe izohamba iye emgodini wesikhunta.
Ukudalwa kwesikhunta - Lesi "sihlahla sephethini" sifakwe kusilayidi wezinhlayiya ezinhle zobumba, ezigqokiswe izinhlayiya ezimahholo kakhulu, bese zomiswa zakha igobolondo le-ceramic elizungeze amaphethini nohlelo lokubiyela. Le nqubo iyaphindwa kuze kube yilapho igobolondo likhulu ngokwanele ukumelana nensimbi encibilikile elizobhekana nayo. Igobolondo bese lifakwa kuhhavini bese i-wax iyancibilika ishiye igobolondo elingenalutho le-ceramic elisebenza njengesikhunta esisodwa, yingakho igama elithi "wax elahlekile" lisakazwa.
Ukuthela - Isikhunta sishiswa esithandweni somlilo size sifike cishe ku-1000 ° C (1832 ° F) bese insimbi encibilikisiwe ithelwa isuka kuladle iye ohlelweni lokubiyela lwesikhunta. Ukuthululwa kuvame ukutholwa ngesandla ngaphansi kwamandla adonsela phansi, kepha ezinye izindlela ezinjenge-vacuum noma ingcindezi kwesinye isikhathi kuyasetshenziswa.
Ukupholisa - Ngemuva kokuthi isikhunta sigcwalisiwe, insimbi encibilikisiwe iyavunyelwa ukupholisa futhi iqine ibe sesimweni sokusakaza kokugcina. Isikhathi sokupholisa sincike ebunzimeni bengxenye, ubukhulu besikhunta, nezinto ezisetshenzisiwe.
Ukusakaza ukusakaza - Ngemuva kokuthi insimbi encibilikile selehlile, isikhunta singaphulwa bese kukhishwa ukusakaza. Isikhunta sobumba ngokuvamile siphuka kusetshenziswa amajetshi wamanzi, kepha kunezinye izindlela eziningi ezikhona. Uma sezisusiwe, izingxenye zihlukaniswa nohlelo lokufaka amasango ngokusaha noma ngokuqhekeka okubandayo (kusetshenziswa i-nitrogen engamanzi).
Iyaqeda - Izikhathi eziningi, kusetshenziswa imisebenzi yokuqedela njengokugaya noma ukufaka isanda ukuze bushelelezi ingxenye emasangweni. Ukwelashwa ngokushisa kwesinye isikhathi kuyasetshenziselwa ukuqina ingxenye yokugcina.
