I-cast iron, ikakhulukazi ehlanganisa i-grey cast iron kanye ne-ductile (nodular) cast iron isetshenziswa kakhulu ekubunjweni ngezinqubo ze-cast iron.ukuphonsa isihlabathi, ukubunjwa kwegobolondo, ukubunjwa kwesihlabathi esimboziwe noma ukukhishwa kwegwebu elilahlekile. Kodwa-ke, esimweni esithile esikhethekile, inqubo yokutshala imali elahlekile ye-wax iphinde isetshenziswe ngenxa yobuso bayo obuhle kanye nokunemba okuphezulu. Kwa-RMC, siphinde sibe nekhono lokuphonsa insimbi empunga ne-ductileukunemba elahlekile utshalomali lwe-wax castingusebenzisa i-silica sol kanye nengilazi yamanzi ekwakheni amagobolondo.
Lapho insimbi eyinsimbi ipholiswa kancane kancane, i-cementite ibola ibe insimbi nekhabhoni ngendlela yegraphite ebizwa ngokuthi i-graphitization. Ama-ayini okusansimbi lapho iphesenti elikhulu likasimende liboliswa yi-graphitization abizwa ngokuthi izinsimbi ezimpunga. I-cast iron lapho i-graphitization ingazange yenzeke, i. e, yonke ikhabhoni isesimweni esihlanganisiwe, ibizwa nge-iron cast iron. Inqubo yokwenza i-graphitization idinga isikhathi ngakho-ke, lapho insimbi ewuketshezi ipholiswa ngokushesha, kungaba ne-white cast iron. I-iron cast emhlophe iqhathaniswa nezakhiwo ze-carbon steels ephezulu. Kodwa-ke, i-brittle kakhulu futhi ngenxa yalokho ayisetshenziselwa izingxenye zesakhiwo. Iwusizo ezingxenyeni lapho ukuguga kukhona khona. Amandla okuqina ayahluka phakathi kuka-170 kuya ku-345 MPa futhi ngokuvamile angaba ngu-240 MPa. Ubunzima busukela ku-350 kuye ku-500 BHN. Uma kubhekwa ubulukhuni obuphezulu kakhulu, amandla omshini ampofu futhi ngokuvamile aqedwa ngokugaya.

Ukufakwa kwe-investimenti (noma ukukhishwa kwe-wax elahlekile) kubhekisela ekwakhekeni kwe-ceramic ezungeze amaphethini we-wax ukuze kwakheke isikhunta sengxenye eningi noma eyodwa ukuthola insimbi encibilikisiwe. Le nqubo isebenzisa inqubo yephethini ye-wax ebunjwe ngomjovo esebenzisekayo ukuze kuzuzwe amafomu ayinkimbinkimbi anekhwalithi ehlukile.s. Ukunemba kokutshala imaliingafinyelela ukunemba okukhethekile kuzo zombili izingxenye zokuphonsa ezincane nezinkulu ezinhlobonhlobo zezinto.
Ukwakha isikhunta, iphethini ye-wax, noma iqoqo lamaphethini, licwiliswa ezintweni zobumba izikhathi eziningana ukuze kwakhiwe igobolondo eliwugqinsi. Inqubo ye-De-wax ilandelwa inqubo eyomile yegobolondo. Khona-ke igobolondo le-ceramic elingenawax liyakhiqizwa. Insimbi encibilikisiwe ibe isithelwa emigodini yegobolondo le-ceramic noma iqoqo, futhi uma seliqinile futhi selipholile, igobolondo le-ceramic liyanqanyulwa ukuze liveze into yokugcina eyinsimbi.
