Kuponya nkhungu kumatanthawuza nkhungu yomwe imagwiritsidwa ntchito popanga ma castings popanga.Kuponyera zisamere zimagwirizana ndi ndondomeko yoponyera, makamaka kuphatikizapo zitsulo zopangira mphamvu yokoka, zitsulo zopangira mphamvu zowonongeka (zojambula zowonongeka), zojambulajambula zotsika kwambiri, kufinya zojambulajambula, ndi zina zotero.Popanga zoponya, izi zimakhudza kwambiri mtundu wa castings.Kuwongolera kwaukadaulo wakuponya ndikofunikira kwambiri pakuwongolera mawonekedwe a castings, kupanga ma casting atsopano ndikuwongolera kuchuluka kwa makina oyandikira.Kupita patsogolo kwaukadaulo wopangira nkhungu kudzapereka mawonekedwe olondola, ovuta komanso apamwamba kwambiri pamagalimoto, mphamvu zamagetsi, zomanga zombo, zoyendera njanji, zamlengalenga ndi mafakitale ena, ndikulimbikitsa kuwongolera kwamakampani opanga zinthu.

Ndi chitukuko chachangu cha mafakitale monga magalimoto, njinga zamoto, ndi ndege, nkhungu zoponya zikukula pamlingo wopitilira 25% pachaka.Ukadaulo woponyera nkhungu wapita patsogolo kwambiri, koma chotchinga chachikulu cha aluminiyamu alloy injini choyimiridwa ndi magalimoto ndi nkhungu zovuta zoponya kufa zimadalira kwambiri zobwera kunja.makampani a galimoto ndi njinga zamoto m'dziko langa alowa m'nyengo ya kukula mofulumira, ndipo zotsatira zake zawonjezeka kwambiri kwa zaka zambiri zotsatizana.Titha kulosera kuti m'zaka 10 mpaka 20 zikubwerazi, kupanga nkhungu kudziko langa kupitilizabe kukhudzidwa ndikukula mwachangu makamaka kuchokera kumakampani amagalimoto.Pankhani ya kuteteza mphamvu ndi kuchepetsa umuna, kukula kwa zitsulo zopangira mphamvu yokoka zachitsulo kudzachepa, pamene zitsulo zotayidwa ndi aluminiyamu-magnesium alloy die-casting molds, low-pressure kuponyera nkhungu ndi kufinya kuponya nkhungu zidzawonjezeka kwambiri.
