Kupangandi kupanga zitsulo zopanda kanthu pamwamba ndi pansikupangakufa mu chipinda nkhungu anakakamizika pulasitiki otaya akamaumba, kuti apeze mawonekedwe azojambulamogwirizana ndi nkhungu chipinda, amatchedwa kufa forging.Malinga ndi mtundu wokhazikika wa forging die, imatha kugawidwa m'matayala okhazikika ndi matayalakufa kusaka.
1. Zokhazikikakufa kusaka kupangakufa kumapangidwa ndi kufa kumtunda ndi kufa kwapansi, komwe kumayikidwa pamutu wa nyundo ndi nyundo yopangira nyundo, kuyanjanitsa kwapamwamba ndi pansi kumatsimikiziridwa ndi nyundo yopangira kufa.Popanga, chopanda chotenthetseracho chimayikidwa m'chipinda chapansi, ndipo mutu wa nyundo umayendetsa chapamwamba kuti chipange, kotero kuti chitsulo chimayenda ndikudzaza chipinda choferamo kuti chipangekupanga, ndipo chitsulo chowonjezeracho chimakanikizidwa mumsewu wowuluka kuti apange m'mphepete mwake, kenako amadulidwa pambuyo pake.kupanga. Ifa kusakambali ndi akalumikidzidwa zovuta, ayenera kutsegula angapo kufa anaboola kwakufa kusaka, kotero kuti billet mu angapo kufa anaboola pang'onopang'ono kupanga, potsirizira pake anamanga mu mawonekedwe ankafuna mu chomaliza kufa anabowola.Zokhazikikakufa kusakaali ndi ubwino wa zokolola zambiri,upangiri wabwino,mawonekedwe ovuta ndi kupulumutsa zitsulo zakuthupi, zomwe ndi njira yoyambira kufakupanga.Koma zimafunika zodulakufa kusakazida ndi kufa, kukula kwakupangaimachepetsedwa ndi matani a kufakupangazida.Choncho, ndi oyenera kupanga misa.

2. Turokufa kusakakukonza matayala kumachitikazopanda pakeZida, popanda zida zopangira zida, kufa kwachitsulo komwe kumagwiritsidwa ntchito ndikosavuta, kutulutsa kwakukulu, kulimba kwabwinoko, kumatha kupulumutsa chitsulo, kuchepetsa mtengo.Komabe, nthawi zambiri matayala opangira matayala, chitsulo chapamwamba ndi chapansi chiyenera kusunthidwa pamanja, chomwe chimakhala ndi mphamvu zambiri zogwirira ntchito ndipo zimakhudza kupititsa patsogolo kwa zokolola.Choncho, amagwiritsidwa ntchito kwambiri popanga timagulu tating'onoting'ono tating'ono ndi tating'onoting'ono.M'machitidwe ambiri otsekedwa otsekedwa, kutentha kwa zinthu zopangira ndipamwamba kuposa kufa.Zotsatira za kupsyinjika kwa kupsinjika kwa zokolola ndizochepa, koma zotsatira za kuthamanga kwa deformation zimakhala zofunikira kwambiri.Choncho, kudalira zokolola kupsyinjika pa mlingo mapindikidwe mwachionekere osiyana zitsulo zosiyanasiyana ndi kaloyi aloyi pamene zitsulo zambiri otentha apanga pamwamba recrystallization kutentha.Pa kutentha kwa chipinda, mphamvu ya deformation pa kupsinjika kwa zokolola zazitsulo zambiri ndizochepa kwambiri.
