Kuponya mchenga ndi njira yachikale komanso yamakono. Amagwiritsa ntchito mchenga wobiriwira (mchenga wonyowa) kapena mchenga wouma kupanga makina owumba. Kuponyera mchenga wobiriwira ndi njira yakale yoponyera yomwe imagwiritsidwa ntchito m'mbiri. Popanga nkhungu, mapangidwe opangidwa ndi matabwa kapena zitsulo ayenera kupangidwa kuti apange dzenje. Chitsulo chosungunulacho chimatsanulira mu mtsempha kuti apange zoponyera pambuyo pozizira ndi kulimba. Kuponya mchenga ndikotsika mtengo kuposa njira zina zopangira nkhungu komanso gawo loponyera ma unit. Mchenga kuponyera, nthawizonse zikutanthauza wobiriwira mchenga kuponyera (ngati palibe kufotokoza wapadera). Komabe, masiku ano, njira zina zoponyamo zimagwiritsanso ntchito mchenga kupanga nkhungu. Ali ndi mayina awo, monga kuponya chipolopolo cha chipolopolo, kuponyera mchenga wa furan (palibe mtundu wophika), kutayika kwa thovu ndi kuponya vacuum.
Ubwino wa Sand Casting:
✔ Mtengo Wotsika chifukwa cha nkhungu zake zotsika mtengo komanso zobwezerezedwanso komanso zida zosavuta zopangira.
✔ Kulemera kwa ma unit osiyanasiyana kuchokera ku 0,10 kg mpaka 500 kgs kapena kupitilira apo.
✔ Mapangidwe Osiyanasiyana kuchokera ku mtundu wosavuta kupita ku mtundu wovuta.
✔ Zoyenera kupanga zamitundu yosiyanasiyana.
