Ezimweni eziningi, amagiya e-powder metallurgy anezidingo eziphansi zezakhiwo zemishini kanye nokunemba okuphezulu kobukhulu.Ngokuvamile, ukuminyana kungu-6.9 ~ 7.1.Inqubo yokwakha ayiphezulu.Inqubo ye-sintering iphezulu.Ukuze uvimbele ukubola kwe-sintering, i-Cu ingangezwa.I-Anti-sintering shrinkage.Ngokuthuthuka kobuchwepheshe, isidingo sezingxenye ezisekelwe ku-powder metallurgy iron-based high-performance siya ngokuya sikhuphuka, okumele ikhulise ukuminyana kwe-powder compact, ebeka phambili izidingo eziphakeme enqubweni yokwakha, futhi ithuthukise ubuchwepheshe obufana nokufudumala. ukucindezela nokucindezela ngesivinini esikhulu., Ukuminyana kwezingxenye kungafinyelela ku-7.2 ~ 7.4.Ukuze uqhubeke uthuthukisa izakhiwo zemishini yezingxenye ze-powder metallurgy, kuyadingeka futhi ukwandisa ukuminyana kwama-compact.Lokhu kufanele kucatshangelwe kusukela ekulungiseleleni impushana.Ubuchwepheshe be-Pulverizing kanye nobuchwepheshe be-powder pretreatment sekugxilwe kuyo.Manje amanzi asezingeni eliphezulu asetshenziselwe i-athomu yensimbi eyimpushana ukwenza ipulasitiki ibe yimpushana.Ukucutshungulwa, ukuminyana okuhlangene okuluhlaza kungafinyelela ngaphezu kuka-7.5, okuyizinga eliphakeme kakhulu lezingxenye ezisekelwe ku-iron eziyimpushana namuhla, okwakungenakucatshangwa eminyakeni eyishumi edlule.izingxenye zensimbi ngokwezifiso

izingxenye zensimbi eziyimpuphu

Manje ifektri yethu i-OEM izinhlobo eziningi zamagiya aqukethe: amagiya elanga acwebile, amagiya angasebenzi ahlanganisiwe, amagiya ahlanganisiwe, iphinikhodi, amagiya ensimbi afakwe insimbi / amagiya ensimbi, igiya lebhokisi leplanethi, amagiya amancane.
