Ufa zitsulo zopangidwa ndi zitsulo zozikidwa pazigawo zomangidwa ndi zitsulo zopangidwa ndi teknoloji ya ufa wachitsulo ndi ufa wachitsulo kapena aloyi zitsulo ufa monga zopangira zazikulu.Zofunikira pazigawo zamtundu uwu ndi kukhala ndi mphamvu zokwanira zamakina, kukana kuvala, kukonza bwino makina, komanso nthawi zina kutentha ndi kukana dzimbiri.Powder metallurgy iron-based parts amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana azachuma cha dziko.Makamaka m'makampani oyendetsa magalimoto, 60% mpaka 70% ya zida zachitsulo zochokera kumayiko otukuka zimagwiritsidwa ntchito m'magalimoto, monga ma camshafts, mipando yotulutsa valavu, zoyika pampu yamadzi ndi magiya osiyanasiyana.
Makhalidwe a ufa zitsulo zopangidwa ndi zitsulo zopangidwa ndi chitsulo: (1) Zigawozo zimakhala zolondola kwambiri, zomwe zingakhale zochepa komanso popanda kudula;(2) Kusayenda bwino.Poyerekeza ndi zitsulo wandiweyani, chitsulo-based powder metallurgy structural parts amagawana pores mofanana.Ma pores omwe amagawidwa mofanana amatha kuthetsa mafuta odzola kuti apititse patsogolo zinthu zotsutsana ndi mikangano, ndipo ma pores ozungulira omwe amagawanika mofanana amathandizanso kukana kutopa kwa ziwalozo pansi pa zovuta zingapo ndi mphamvu zochepa.Komabe, pores amatha kuchepetsa mawotchi amakina azinthu monga kulimba kwamphamvu, kutalika pambuyo pakusweka, komanso kulimba kwazinthu, komanso kukhudza kukana kwa dzimbiri kwa zinthu, ma conductivity amafuta, madulidwe amagetsi, ndi maginito permeability.Komabe, malinga ndi zofunikira za ntchito, kukula kwa pore ndi kugawa kwa pore kumatha kuwongoleredwa ndikusintha zomwe zikuchokera, kukula kwa tinthu ndi njira.Komabe, kukula kwa kabowo kocheperako, kumakwera mtengo wopangira.(3) Palibe tsankho la zinthu zophatikizika ndi njere zabwino komanso zofananira zamakristalo.Ma alloying muzinthu zopangira chitsulo amazindikirika powonjezera ma alloying element powders ndikusakaniza.Popanda kusungunula, chiwerengero ndi mitundu ya zinthu zowonjezera zowonjezera sizimakhudzidwa ndi kuchepa kwa kusungunuka ndi kugawanika kwa kachulukidwe, ndipo ma alloys opanda tsankho ndi pseudo-alloys akhoza kukonzekera.Ma pores amalepheretsa kukula kwa njere, motero njere zamapangidwe achitsulo zimakhala zabwino kwambiri.
