I-OEM ngokwezifiso zensimbi ezimpunga ezikhiqizwa ngokunemba okulahlekile kwe-wax yokutshala imali kanye nomshini we-CNC.
Ngenxa yobulula bayo bemishini, amandla aphezulu okucindezela, ukuguquguquka okungcono kokushisa kanye nokumuncwa kokudlidliza okuhle kakhulu, insimbi empunga ingenye yensimbi yokuphonsa esetshenziswa kakhulu isikhathi eside kakhulu, ngisho nasekukhiqizweni kwemboni yamanje. Okuqukethwe kwekhabhoni kuyisici esibaluleke kakhulu se-iron empunga (imvamisa engu-2% ukuya ku-4%) ukuze kwakheke amandla aqinile kanye nokusebenza kanzima. Lapho insimbi encibilikisiwe iqinisa amanye ama-carbon precipitate njenge-graphite, yenze ama-flakes amancane, angajwayelekile ngaphakathi kwesakhiwo sekristalu sensimbi esithuthukisa izici ezifiselekayo zensimbi ewugqinsi, ama-flakes aphazamisa ukwakheka kwekristalu okuholela ekuhlakazekeni kwesici se-cast iron.
Ukuthuthukiswa kwe-grey cast iron ikakhulukazi kuqhutshwa amandla aphezulu. Esikhathini esidlule, indlela eyinhloko yokuthuthukisa ukusebenza kwe-grey cast iron kwakuyi-inoculation. Eminyakeni yamuva nje, indlela eyinhloko manje iwukugxila ekuhlanganiseni ingxubevange, futhi ukuze kuthuthukiswe ukusebenza kokusakazwa, izimboni eziningi zensimbi ezimpunga zisebenzisa insimbi ekhonjiwe enokulingana kwekhabhoni ephezulu. Lokhu kubaluleke kakhulu ku-low alloy cast iron. Ngakho-ke, i-grey cast iron iyimpahla efanelekile yokukhiqiza izingxenye zensimbi ze-injini block, izindlu zemishini, isisekelo somshini, izisindo zokubala, izingxenye zesitofu, izingxenye zebhayela, amagobolondo epompo nokunye.

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.
