Njira yaikulu yopangira ndalama zogulira zinthu (Investment casting) imaphatikizapo gawo lililonse lofunika kwambiri, kuyambira kukonzekera zipangizo zopangira mpaka kupanga zinthu zogulira zinthu zolondola. Njirazi zimagwirizanitsidwa ndipo zimagwirizana, zomwe zimaonetsetsa kuti zinthu zogulira zinthu zolondola zimakhala zapamwamba komanso zolondola.
Kukonzekera Kapangidwe ka Nkhungu ndi Sera
Kapangidwe ka digito kamagwira ntchito ngati poyambira pokonzekera mapangidwe a nkhungu ndi sera, pogwiritsa ntchito ukadaulo wapamwamba wa CAD. Mainjiniya amapanga bwino mitundu itatu ya nkhungu. Pambuyo pake, mitundu iyi imasinthidwa kukhala nkhungu zenizeni kudzera mu zida zomangira zolondola kwambiri, kuonetsetsa kuti miyeso ndi mawonekedwe awo zikugwirizana ndi kapangidwe kake ndendende. Ntchito yomangira nkhungu ikamalizidwa, njira yopangira sera imayamba. Apa, sera yosungunuka imalowetsedwa mu nkhungu, ndipo ikazizira, pamakhala sera yogwirizana ndi kuponyedwa komaliza.
Kumanga Zipolopolo
Njira yopangira chipolopolo cha chipolopolo ndi yovuta kwambiri. Poyamba, matope amaikidwa pamwamba pa chitsanzo cha sera, kenako amawaza zinthu zotsutsa monga mchenga wa zircon kapena zinthu zopangidwa ndi mullite, kenako njira yowumitsa. Ndondomekoyi iyenera kubwerezedwa kangapo kuti ipange chipolopolo cholimba chokhala ndi makulidwe okwanira, kuonetsetsa kuti chikhoza kupirira kutentha kwambiri komanso kukhudzidwa ndi chitsulo chosungunuka panthawi yopangira.
Kusungunula ndi Kutaya
Kusungunula ndi kuponya ndi njira zofunika kwambiri popanga zinthu zopopera. Poyamba, chitsanzo cha sera chimachotsedwa kudzera mu kutentha, ndikusiya dzenje la chipolopolo cha nkhungu. Pambuyo pake, chipolopolo cha nkhungu chimachitidwa chithandizo chotentha kuti chikhale cholimba kwambiri. Kenako, chitsulocho chimasungunuka kufika kutentha koyenera ndikutsanulira m'dzenje la chipolopolo cha nkhungu pogwiritsa ntchito ukadaulo wa vacuum casting. Pambuyo poziziritsa ndi kulimba, kuponya kwachitsulo komwe kumakwaniritsa zofunikira kumapezeka.
Kukonza Pambuyo
Gawo lomaliza kukonza limaphatikizapo masitepe angapo, kuphatikizapo kugwedeza, kudula, kumaliza, ndi kuyang'anira. Kugwedeza kumathandizira kuchotsa chipolopolo cha nkhungu, kudula kumalekanitsa kuponyera ndi dongosolo lotsekera, kumaliza kumawonjezera kulondola kwa mawonekedwe ndi kutsirizika kwa pamwamba pa kuponyera, ndipo kuyang'anira kumaonetsetsa kuti kuponyera kukukwaniritsa zofunikira pa kapangidwe ndi miyezo ya khalidwe.
