Ngokuvumelana nezihlanganisi ezihlukene zokwakha amagobolondo, ukufakwa kwe-investimenti kungahlukaniswa ngokufaka utshalomali kwe-silica sol binder, ukusakaza kwe-investment binder yengilazi yamanzi kanye nokufaka utshalomali ngezingxube zakhona njengezinto ezihlanganisayo. I-silica sol iyisibopho esivamile esisekelwe emanzini esine-silicic acid colloid structure. Kuyisixazululo se-polymer colloidal lapho izinhlayiya ze-silica ezihlakazeke kakhulu zincibilika emanzini. Izinhlayiya ze-colloidal ziyindilinga futhi zinobubanzi obungu-6-100 nm. Inqubo yokutshala izimali ukwenza igobolondo yinqubo yokugaya. Kunezici eziningi ezithonya i-gelation, ikakhulukazi i-electrolyte, i-pH, ukugxila kwe-sol kanye nezinga lokushisa. Kunezinhlobo eziningi zama-silica sols ezithengiswayo, futhi esetshenziswa kakhulu i-alkaline silica sol enokuqukethwe kwe-silica okungama-30%. Ukuze unqobe ukushiyeka komjikelezo omude wokwenza amagobolondo wegobolondo le-silica sol, i-silica sol eyomisa ngokushesha iye yathuthukiswa eminyakeni yamuva. Inqubo yokwenza igobolondo le-silica sol ilula. Inqubo ngayinye inezinqubo ezintathu: ukumboza, ukuhlanganisa, nokomisa. Inqubo ngayinye iphindaphindiwe izikhathi eziningi ukuze uthole igobolondo le-multilayer lobukhulu obudingekayo.
Enqubweni yokwenza igobolondo le-silica sol, ukomisa kuyinqubo ebaluleke kakhulu. Ngokumiswa, amanzi ayashintshashintsha, ama-silica sol gels, kanye nezinhlayiya eziphikisayo zihlanganiswe ngokuqinile ndawonye, ngaleyo ndlela zithola igobolondo lamandla aphezulu. Lokhu ukulungiselela okuhle kokulingisa okulandelayo. Ukubunjwa okutholwe inqubo yokwenza igobolondo le-silica sol kunobugwegwe obuphansi, ukunemba kobukhulu obuphakeme kanye nomjikelezo omude wokwenza amagobolondo. Le nqubo isetshenziswa kakhulu ekukhipheni ama-alloys amelana nokushisa okuphezulu, izinsimbi ezikwazi ukumelana nokushisa, izinsimbi ezingenasici, izinsimbi ze-carbon, ama-alloys aphansi, ama-alloys e-aluminium nama-alloys ethusi.
Ukunemba kwe-silica sol elahlekile inqubo yokufaka utshalomali kwe-wax ifaneleka ukukhiqizwa okuphindaphindekayo kwezingxenye zomumo wenetha kusuka ezinhlobonhlobo zezinsimbi nama-alloys asebenzayo. Nakuba ngokuvamile isetshenziselwa ukulingisa okuncane, le nqubo isetshenziselwe ukukhiqiza amafreyimu eminyango yendiza ephelele, enensimbi efika ku-500 kgs kanye nokusakazwa kwe-aluminium kufika ku-50 kgs. Uma kuqhathaniswa nezinye izinqubo zokulingisa ezifana ne-die casting noma ukwenza isihlabathi, kungaba inqubo ebizayo. Kodwa-ke, izakhi ezingakhiqizwa kusetshenziswa ukufakwa kwe-investimenti zingahlanganisa amakhonsathi ayinkimbinkimbi, futhi ezimeni eziningi izingxenye ziphonswa eduze komumo wengqikithi, ngakho-ke zidinga ukusetshenzwa kabusha okuncane noma zingasasebenzi lapho kwasakazwa.
Ngokwezinga lokuqukethwe kwekhabhoni, i-carbon steel for casting ngokuvamile ihlukaniswe ibe yi-low carbon steel, i-medium carbon steel kanye ne-high carbon steel. Ama-cast carbon steels awo wonke amazwe emhlabeni ngokuvamile ahlukaniswa ngokwamandla awo, futhi amamaki ahambisanayo ayakhiwa.
Ngokuphathelene nokwakheka kwamakhemikhali e-carbon steel, ngaphandle kwe-phosphorus nesibabule, akukho mingcele noma imingcele ephezulu kuphela kwezinye izakhi zamakhemikhali. Ngaphansi kwesisekelo esingenhla, ukwakheka kwamakhemikhali ensimbi ye-cast carbon kunqunywa yi-foundry ngokusho kwezakhiwo ezidingekayo zemishini.
Izindlela zokwelapha ukushisa kwe-carbon steel castings ngokuvamile zi-annealing, normalizing noma normalizing + tempering. Kokunye ukuphonswa kwensimbi ephezulu yekhabhoni, ukucisha nokushisa nakho kungasetshenziswa, okungukuthi, ukucisha + izinga lokushisa eliphakeme, ukuze kuthuthukiswe izici ezibanzi zemishini yokusakazwa kwe-carbon steel. Ukukhishwa kwensimbi encane ye-carbon kungacinywa ngokuqondile futhi kuncishiswe kusuka kusimo sokusakazwa. Ukuze uthole ukukhishwa kwensimbi yensimbi yezinga elikhulu noma eyinkimbinkimbi, kufanelekile ukwenza ukwelashwa kokucisha nokushisa ngemva kokwelashwa okujwayelekile.
Emkhakheni wemboni yokusansimbi nensimbi, izinsimbi zayoni zisho izinsimbi nama-alloys azo aqukethe i-iron. Insimbi eyinsimbi ihlanganisa insimbi nensimbi yengulube futhi izisekelo zivame ukuhlukanisa zibe izigaba ezimbili ezinkulu: insimbi eyinsimbi (insimbi empunga, i-ductile cast iron, insimbi ethambile ethambile, i-vermicular graphite cast iron njll.) kanye nensimbi ekhonjiwe (cast carbon steel, cast). i-alloy steel, insimbi engagqwali njll). Ngenqubo elahlekile yokuphonsa igwebu, i-RMC Casting Foundry ingathela insimbi empunga, i-ductile iron, i-alloy steel ne-carbon steel.
