Silica sol casting ndiyo nzira yekukanda iyo inoshandisa silica sol (silica solution) seyakasungirirwa kugadzira mold yekukanda. Iyo simbi inokandwa inogadzirwa ne silica sol casting ine nzvimbo yakanaka uye yakanyanya kurongeka uye iyo general dimensional tolerance giredhi inosvika kuCT4 - CT6. Uye maitiro aya ndiwo makuru ekudyara ekukanda maitiro eRMC ekukandira simbi isina tsvina uye alloy simbi castings. Isu tanga tichigadzira tekinoroji nyowani yekunamatira zvinhu kuti tiwane zvakanyanya hupfumi uye hunoshanda hwekunamira zvinhu zvekudyara indasitiri yekukanda.

Icho chiitiko chinokatyamadza kuti silica sol casting process inotsiva iyo yakaoma yakaderera yemvura girazi maitiro muindasitiri yekukanda chaiyo, kunyanya yekukanda simbi isina tsvina uye alloy simbi yekukanda. Kunze kweiyo yakagadziridzwa yekuumba zvinhu, iyo silica sol yekukanda maitiro zvakare iri kuvandudzwa kune yakanyanya kusimba uye kushoma kuwedzera kupisa.
Investment (rasika wakisi) inzira yekukandira nemazvo iyo inoburitsa zvinhu zvakaomarara zviri pedyo-neti-shape uchishandisa kudzokororwa kwewakisi.Investment castingkana kurasika wakisi isimbi inogadzira nzira iyo inowanzo shandisa wakisi pateni yakakomberedzwa negoko re ceramic kugadzira mold ye ceramic. Kana goko raoma, wakisi inonyunguduka, kuchisiya mold chete. Zvadaro chikamu chekukanda chinoumbwa nekudururira simbi yakanyungudutswa mumucheka weceramic.
Zvinoenderana neakasiyana mabhaidha echivakwa chegoko, iyo yekukanda mari inogona kukamurwa kuita silica sol binder investimendi yekukandira, mvura girazi binder investimendi kukanda uye mari yekukanda nemisanganiswa yavo sebinder zvinhu. Silica sol yakajairika mvura-based binder ine silicic acid colloid chimiro. Iyo polymer colloidal mhinduro umo yakapararira zvakanyanya silica particles inonyungudika mumvura. Iwo ma colloidal particles ane denderedzwa uye ane dhayamita ye6-100nm. Iyo nzira yekukandira mari kugadzira iyo goko ndiyo maitiro ekugelling. Pane zvinhu zvakawanda zvinopesvedzera gelation, kunyanya electrolyte, pH, sol concentration uye tembiricha. Kune akawanda marudzi ekutengesa silica sols, uye inonyanya kushandiswa ndeye alkaline silica sol ine silica yemukati ye30%. Kuti ukunde kusakwana kweiyo refu-yekugadzira goko reiyo silica sol shell, inokurumidza-kuomesa silica sol yakagadzirwa mumakore achangopfuura. Maitiro ekugadzira silica sol shell ari nyore. Nzira imwe neimwe ine maitiro matatu: kupfekedza, kuisa jecha, uye kuomesa. Maitiro ega ega anodzokororwa kakawanda kuti awane multilayer goko rehukobvu hunodiwa.
Mu silica sol shell kugadzira maitiro, kuomesa ndiyo inonyanya kukosha maitiro. Kuburikidza nekuomeswa, mvura inoputika, iyo silica sol gels, uye zvimedu zvinoramba zvakasunganidzwa zvakasimba pamwe chete, nokudaro zvichiwana goko rakasimba. Iyi igadziriro yakanaka yekukanda kunotevera.
Iko kukanda kunowanikwa ne silica sol shell kugadzira maitiro kune yakaderera pamusoro roughness, yakakwirira dimensional kunyatsoita uye kureba shell kugadzira kutenderera. Iyi nzira inoshandiswa zvakanyanya mukukanda alloys anodzivirira kupisa-kupisa, masimbi asingasviki, simbi isina tsvina, carbon steels, low alloys, aluminium alloys uye copper alloys.
Iyo silica sol precision yakarasika wax investment casting process inokodzera kudzokorora kugadzirwa kwenet shape casting componentskubva kune zvakasiyana-siyana zvakasiyana-siyana zvesimbi uye high performance alloys. Kunyange zvazvo ichiwanzo shandiswa kuita zvidiki zvekukandira, maitiro aya akashandiswa kugadzira mafuremu emadhoo endege akazara, ane simbi inokandwa inosvika 500 kgs uye aluminium castings inosvika makumi mashanu kgs. Kuenzaniswa nemamwe maitiro ekukanda akadai sekukanda kufa kanakukanda jecha, inogona kuva nzira inodhura. Nekudaro, izvo zvikamu zvinogona kugadzirwa uchishandisa investment casting inogona kusanganisira yakaoma contours, uye kazhinji zvikamu zvinokandwa padhuze net mambure, saka zvinoda kushoma kana kusazoitwazve kana ikandwa.
