Gray cast iron investment castings ndi njira yolondola yopangira sera yotayika yopangidwa ndi chitsulo chotuwa. Ku RMC Foundry, titha kukupatsirani ntchito zamakina opangidwa ndi makina a CNC malinga ndi zojambula zanu, kugwiritsa ntchito ndi zomwe mukufuna.

Kuponyedwa kwachitsulo cha Gray cast nthawi zambiri kumapangidwa ndi njira yopangira mchenga, komabe, pamapangidwe ena omwe amafunikira kulondola molondola komanso kukhala ndi mawonekedwe ovuta,ndondomeko yopangira ndalamandi chisankho chabwino.

Tikaponyera chitsulo chotuwa, timatsatira mosamalitsa kapangidwe kake ka mankhwala ndi makina amakina malinga ndi nyenyezi kapena zofunikira kuchokera kwa makasitomala. Kupatula apo, tili ndi kuthekera ndi zida zoyesera ngati pali zolakwika zoponya mkati mwa mchenga wachitsulo wotuwa.

Ngakhale zitsulo zotayidwa zimatha kukhala ndi mpweya wapakati pa 2 mpaka 6.67, malire enieni amakhala pakati pa 2 ndi 4%. Izi ndi zofunika makamaka chifukwa cha makhalidwe awo abwino oponya. Iron imvi ndiyotsika mtengo kuposa chitsulo cha ductile, koma imakhala ndi mphamvu zotsika kwambiri komanso ductility kuposa chitsulo cha ductile. Imvi chitsulo sangathe m'malo mpweya zitsulo, pamene chitsulo ductile akhoza m'malo mpweya chitsulo zinthu zina chifukwa mkulu wamakokedwe mphamvu, zokolola mphamvu ndi elongation wa chitsulo ductile.

Kuponyera ndalama (phula lotaika) ndi njira yopangira mwatsatanetsatane mawonekedwe a ukonde pogwiritsa ntchito kufananiza kwa sera. Kuponyera ndalama kapena kutayika sera ndi njira yoponyera zitsulo 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.

Silica sol casting process ndiye njira yayikulu yopangira ndalama pa RMC Investment casting foundry. Takhala tikupanga ukadaulo watsopano wa zomatira kuti tikwaniritse zomatira zotsika mtengo komanso zogwira mtima kuti timange chipolopolo cha slurry. Ndizovuta kwambiri kuti Silica sol casting process ilowa m'malo mwa magalasi otsika kwambiri amadzi, makamaka poponya zitsulo zosapanga dzimbiri komanso zitsulo za aloyi. Kupatula zida zatsopano zomangira, njira yopangira silika sol yapangidwanso kuti ikhale yosasunthika komanso kutentha pang'ono.
