kuponya mchenga ndi njira wamba yoponyera yomwe ili ndi zabwino izi:
1. Mtengo wotsika: Poyerekeza ndi njira zina zoponyera mchenga, mtengo wa mchenga ndi wotsika.Mchenga ndi zitsulo zomwe zimapezeka kwambiri komanso zotsika mtengo, ndipo njira yopangira mchenga ndi yosavuta, ndipo safuna zipangizo zovuta ndi teknoloji.
2. Ufulu wamapangidwe apamwamba: kuponyedwa kwa mchenga kungathe kusinthasintha kupanga zojambula zamitundu yosiyanasiyana ndi kukula kwake, zomwe ziri zoyenera kupanga mbali zovuta komanso zosasinthika.Wopangayo amatha kusintha mawonekedwe, mawonekedwe ndi njira yolekanitsa ya nkhungu yamchenga malinga ndi kufunikira kuti akwaniritse zofunikira zamitundu yosiyanasiyana.
3. Good dimensional bata of castings: mchenga kuponyera kumatha kuthetsa shrinkage zolakwika za castings kumlingo wakutiwakuti.Chipinda chokwanira chocheperako chimaperekedwa mu nkhungu yamchenga kuti igwirizane ndi kukula kwa mzere wa kuponyera panthawi yozizirira, motero kumapangitsa kukhazikika kwa kuponya bwinoko.
4. Kusinthasintha kwamphamvu: kuponyedwa kwa mchenga ndikoyenera kuponyera zitsulo zosiyanasiyana ndi aloyi, kuphatikizapo chitsulo, chitsulo, aluminiyamu, mkuwa ndi zina zotero.Mitundu yosiyanasiyana ya mchenga imatha kusankhidwa malinga ndi zofunikira za kuponyera kuti mupeze zotsatira zabwino zoponyera.
Mfundo zotsatirazi ziyenera kukumbukiridwa poponya nkhungu yamchenga:
1. Ubwino wa mchenga: mchenga uyenera kukhala ndi mphamvu inayake ndi kukana kutentha, ukhoza kupirira mphamvu ya zitsulo zamadzimadzi ndi kutentha.Pamwamba pa nkhungu yamchenga iyenera kukhala yosalala, yopanda ming'alu ndi zolakwika kuti zitsimikizire ubwino wa kuponyera.
2. Kuthira kutentha: Ndikofunikira kwambiri kuwongolera kutentha kwazitsulo zamadzimadzi.Kutentha kwambiri kumayambitsa kuwotcha mchenga, kupindika kapena kusweka;Kutentha kochepa kwambiri kungayambitse kudzaza kosakwanira ndi kuponya mavuto abwino.
3. Kuthamanga kwachangu kumatha: Liwiro lololera loponyera ndi mode lingalepheretse kuchitika kwa zolakwika monga pores ndi mabowo amchenga.Kuthamanga kopitilira muyeso kwakanthawi kochepa kuyenera kutsatiridwa kuti nkhungu yamchenga ipitirire popanda kuyambitsa mpweya.
4. Kuthira dongosolo: Kwa kuponyera kovutirapo, makamaka omwe ali ndi zipata zochulukira, ndikofunikira kukonza dongosolo lothira bwino kuti zitsimikizire kuti zitsulo zamadzimadzi zadzaza m'zigawo zonse, komanso kuti aviod kudzipatula kuzizira adn kusankhana.
5. Kuziziritsa ndi kuchiza: kuponyera kuyenera kuziziritsidwa ndikuthandizidwa mutatha kuthira.Yoyenera kuzirala nthawi ndi njira angapewe ming'alu ndi defromation chifukwa matenthedwe nkhawa, ndi kusintha makina zimatha castings.
Ambiri, pamene akuponya mchenga nkhungu m`pofunika kulabadira kulamulira khalidwe nkhungu mchenga, kuthira kutentha, kuthira liwiro ndi mode, kuthira zinayendera ndi wotsatira kuzirala ndi mankhwala ndondomeko kupeza castings apamwamba.
