Silika sol casting ndi njira yoponyera yomwe imagwiritsa ntchito silika sol (silica solution) ngati zida zomangira kupanga nkhungu. Zopangira zitsulo zopangidwa ndi silika sol casting zimakhala ndi malo abwino komanso olondola kwambiri ndipo magawo onse olekerera amafika ku CT4 - CT6. Ndipo njirayi ndiye njira yayikulu yopangira ndalama ya RMC yopangira zitsulo zosapanga dzimbiri ndi zitsulo za aloyi. Takhala tikupanga ukadaulo watsopano wa zomatira kuti tikwaniritse zomatira zotsika mtengo komanso zogwira mtima pamakampani opanga ndalama.

Ndizovuta kwambiri kuti silika sol casting process ilowa m'malo mwa magalasi otsika kwambiri amadzi mumsika wonse woponyera zitsulo, makamaka poponya zitsulo zosapanga dzimbiri ndi zitsulo zotayira. Kupatula zida zatsopano zomangira, njira yopangira silika sol yapangidwanso kuti ikhale yosasunthika komanso kutentha pang'ono.
Kuponyera ndalama (kutaya sera) ndi njira yoponyera bwino yomwe imapanga tsatanetsatane wa mawonekedwe a ukonde pogwiritsa ntchito mawonekedwe a sera.Investment castingkapena kutayika sera ndi njira yopangira chitsulo yomwe nthawi zambiri imagwiritsa ntchito sera yozunguliridwa ndi chipolopolo cha ceramic kupanga nkhungu ya ceramic. Chigobacho chikauma, sera imasungunuka, ndikusiya nkhungu yokha. Ndiye chigawo choponyera chimapangidwa ndi kutsanulira zitsulo zosungunuka mu nkhungu ya ceramic.
Malinga ndi zomangira zosiyanasiyana zomanga zipolopolo, zopangira ndalama zitha kugawidwa mu silika sol binder Investment casting, madzi galasi binder kuponyera ndalama ndi kuponyera ndalama ndi zosakaniza monga binder zipangizo. Silica sol ndizomwe zimapangidwira m'madzi zomwe zimakhala ndi silicic acid colloid. Ndi polima colloidal njira imene kwambiri omwazikana silika particles sungunuka m'madzi. Ma colloidal particles ndi ozungulira ndipo ali ndi mainchesi a 6-100nm. Njira yopangira ndalama kuti ipange chipolopolo ndi njira ya gelling. Pali zinthu zambiri zomwe zimakhudza gelation, makamaka electrolyte, pH, sol concentration ndi kutentha. Pali mitundu yambiri yazitsulo zamalonda za silika, ndipo zomwe zimagwiritsidwa ntchito kwambiri ndi zamchere zamchere zamchere zomwe zili ndi silica 30%. Pofuna kuthana ndi zofooka za chipolopolo chautali wa chipolopolo cha silica sol, silika yowuma mofulumira yapangidwa m'zaka zaposachedwa. Njira yopangira chipolopolo cha silica sol ndiyosavuta. Njira iliyonse ili ndi njira zitatu: zokutira, kupukuta mchenga, ndi kuyanika. Njira iliyonse imabwerezedwa kangapo kuti mupeze chipolopolo cha multilayer cha makulidwe ofunikira.
Popanga chipolopolo cha silika, kuyanika ndiye njira yofunika kwambiri. Kupyolera mu kuyanika, madzi amasungunuka, silika sol gels, ndi refractory particles amalumikizana mwamphamvu pamodzi, motero amapeza chipolopolo champhamvu kwambiri. Uku ndikukonzekera bwino kwa kuponyera kotsatira.
Kuponyedwa komwe kumapangidwa ndi silika sol kupanga njira kumakhala ndi roughness yotsika, yolondola kwambiri komanso kuzungulira kwa zipolopolo zazitali. Njirayi imagwiritsidwa ntchito kwambiri popangira ma alloys osatentha kwambiri kutentha, zitsulo zosagwira kutentha, zitsulo zosapanga dzimbiri, zitsulo za kaboni, zotayira zochepa, zotayira za aluminiyamu ndi zida zamkuwa.
The silika sol mwatsatanetsatane anataya sera ndalama kuponyera ndondomeko ndi oyenera repeatable kupanganet mawonekedwe kuponyera zigawokuchokera kumitundu yosiyanasiyana yazitsulo ndi ma alloys apamwamba kwambiri. Ngakhale kuti nthawi zambiri amagwiritsidwa ntchito popanga zing'onozing'ono, njirayi yakhala ikugwiritsidwa ntchito popanga mafelemu a zitseko za ndege zonse, zokhala ndi zitsulo zokwana 500 kgs ndi aluminiyumu mpaka 50 kgs. Poyerekeza ndi njira zina zoponya monga kufa kapenakuponya mchenga, ikhoza kukhala njira yokwera mtengo. Komabe, zida zomwe zitha kupangidwa pogwiritsa ntchito kuyika ndalama zimatha kuphatikiza ma contours ovuta, ndipo nthawi zambiri zidazo zimayikidwa pafupi ndi mawonekedwe a ukonde, motero zimafunikira kukonzanso pang'ono kapena kusasinthidwa kamodzi.
