Kuponyera chitsulo nthawi zambiri kumapangidwa ndi mchenga.Kuponyedwa kwa mchenga monga luso lamakono lasankhidwa ngati njira yabwino yopangira zigawo zooneka ngati zolemera kuchokera ku zosakwana mapaundi kupita ku zigawo zazikulu kwambiri.Njirayi ndi yodalirika komanso yotsika mtengo, ngakhale yotsika mtengo chifukwa cha mtengo wa zida.Pafupifupi makonzedwe a gawo lililonse omwe angapangidwe pogwiritsa ntchito njira ina yoponyera akhoza kuchepetsedwa kukhala chitsanzo ndikupangidwa ngati mchenga.Chitsulo chachitsulo ndi aloyi yachitsulo yachitsulo, carbon ndi silicon.Ndi mpweya wa 2.1 mpaka 4.5 % ndi silicon pafupifupi 2.2% ndi pang'ono Sulphur, Manganese ndi Phosphorous.

Kuponyera chitsulo ndi imodzi mwa njira zakale kwambiri padziko lapansi.Chitsulo chosungunula chimasungunuka ndikutsanuliridwa mu nkhungu kapena zitsulo kuti apange gawo la zinthu za kukula kwake ndi mawonekedwe.Chitsulo chachitsulo chingagwiritsidwe ntchito m'mafakitale osiyanasiyana.Popanga Cast Iron, ma alloying zinthu amasankha mtundu wachitsulo chachitsulo.Poyerekeza ndi kuponyedwa kwachitsulo, kuponyedwa kwachitsulo kumakhala ndi ubwino wambiri wa katundu wake.Mitundu yayikulu yachitsulo ndi Grey, Ductile, Compacted graphite, White, Malleable, Abrasion resistant and Austenitic.

Njira zodziwika kwambiri zopangira chitsulo ndi kuumba mchenga wobiriwira, kuumba zipolopolo, kuumba mchenga wa resin ndi njira yotayika ya thovu.

Ndi chitukuko chachikulu m'zaka zapitazi, kupanga kwathu konse kumangochitika zokha ndi mizere yowumba monga mizere yowongoka kapena yopingasa, makina othira okha amayambitsidwa.
