Ubuchwephesha bokwenza utyalo-mali buyenye yezona zindala kunye nezona ziphambili kubugcisa besinyithi.Ikwabizwa ngokuba yi-wax casting elahlekileyo,

yinkqubo yokuphosa echanekileyo esetyenziswa ukwenza iinxalenye zentsimbi ukusuka phantse kuyo nayiphi na ingxubevange, kwaye iqhele ukusetyenziswa ukwenza udonga oluntsonkothileyo, olubhityileyo.

Kwiminyaka engama-5000 eyadlulayo, ngexesha looFaro, yayisetyenziswa ngamaJiphutha ukwenza ubucwebe begolide.Malunga neminyaka eyi-100 eyadlulayo, ukusetyenziswa kwe

Inkqubo yewax elahlekileyo iye yafakwa kwi-inlay zamazinyo kwaye kamva kunye noFakelo lokuFakela uCando.

Phantse ii-alloys ezingama-200 ziyafumaneka ngokufakwa kotyalo-mali.Ezi zinyithi zisusela kwi-ferrous- Steel, isixhobo sentsimbi, intsimbi yekhabhoni kunye nentsimbi yentsimbi ukuya kwi-non-ferrous.

– ialuminiyam, ubhedu kunye nobhedu.

Inkqubo Overview

Inkqubo yotyalo-mali iqala ngepateni.Ngokwemveli, ipateni yayiyinaliti yokungunda kwi-wax efumanekayo.Amasango kunye neendawo zokuphuma zifakwe kwipatheni, ethi ke ifakwe kwi-puree.Emva kokuba zonke iipateni zifakwe kwi-sprue evelisa into ebizwa ngokuba ngumthi wokuphosa.Kwezi ndawo ukuphosa kulungele ukugotywa.Umthi wokugalela ugalelwe ngokuphindaphindiweyo kwi-ceramic slurry ukwenza iqokobhe eliqinileyo elibizwa ngokuba yi-investment.Iipateni ke ziyanyibilika (ekwabizwa ngokuba yi-burnout) yotyalo-mali, ishiya umngxuma wokumila kwenxalenye eza kuphoswa.

I-alloy yensimbi iyancibilika, ngokuphindaphindiweyo kwi-furnace induction, kwaye igalelwe kwi-investment yangaphambili.Emva kokupholisa, iqokobhe liyaqhekeka, iinxalenye zesinyithi zisikwa emthini kwaye amasango kunye neendawo zokuphuma ziyacolwa.
