China OEM customized nodular iron castings zvigadzirwa nejecha mold casting processuyeCNC machining.
Ductile cast iron, inomiririra boka resimbi yakakandwa, inonziwo nodular iron, spheroidal graphite cast iron kana SG iron. Nodular cast iron inowana nodular graphite kuburikidza ne spheroidization uye inoculation kurapwa, iyo inobudirira inovandudza ma mechanic properties yesimbi yakakandwa, kunyanya plastiki uye kuoma, kuitira kuti uwane simba rakakwirira kudarika carbon steel.
Ductile iron haisi chinhu chimwe chete asi chikamu cheboka rezvinhu zvinogona kugadzirwa kuti zvive nehuwandu hwezvinhu kuburikidza nekutonga kwe microstructure. Izvo zvinowanzotsanangudza hunhu hweboka iri rezvinhu chimiro chegraphite. Mune ductile irons, iyo graphite iri muchimiro chemanodule kwete maflakes sezvairi mugrey iron. Iyo yakapinza chimiro chemaflakes e graphite inogadzira kushushikana pfungwa mukati mesimbi matrix uye yakatenderedzwa chimiro chemanodule zvishoma, nekudaro kuvharidzira kusikwa kwekutsemuka uye nekupa iyo inosimudzira ductility inopa alloy zita rayo.
Nodular cast iron yakakurumidza kugadzirwa kuita simbi yakakandwa yechipiri chete kune grey cast iron uye inoshandiswa zvakanyanya. Iyo inonzi "inotsiva simbi yesimbi" inonyanya kureva ductile iron. Ductile iron inowanzo shandiswa kugadzira zvikamu zve crankshafts uye camshafts emotokari, matirakita, uye emukati injini dzinopisa, pamwe nepakati-kudzvanywa mavharuvhu emichina yakawanda.
Muchikamu chekugadzira ductile iron casting products, yakakosha purojekiti timu inofanirwa kugadzwa kuti iite "Design Failure Mode uye Effects Analysis" (DFMEA). Chikwata chepurojekiti kazhinji chine vagadziri vezvigadzirwa, vanogadzira maitiro ekukanda, uye nyanzvi dzekuchengetedza kwezvakatipoteredza. Icho chikuru chemukati chekuongorora kweDFMEA chinofanira kusanganisira kana izvo zvinodiwa zvemhando yekukanda yechikamu chechimiro, maitiro ekukanda echimiro chekukanda, uye maitiro ekukanda ekuchengetedza kwezvakatipoteredza zvinodiwa zvese zvinosangana.

Kuita Hunhu hweDuctile Iron Castings:
• Fluidity uye mitsara shrinkage ye ductile iron iri pedyo zvikuru neiyo yegrey cast iron
• Maitiro ekuderera kwevhoriyamu uye kuumbwa kwekushushikana kwemukati kwakakura kupfuura iyo grey cast iron, iyo inowanzoita shrinkage uye kuputika.
• Simba, plasticity, uye elastic modulus ye ductile iron yakakura kudarika iyo yegrey cast iron, ine good abrasion resistance.
• Shock absorption yakaipisisa kupfuura grey cast iron
Mamiriro ezvinhu eDuctile Iron Castings:
• Kazhinji akagadzirirwa kuva yunifomu madziro ukobvu, uye edza gobvu chikamu anofanira kudzivisa kana zvichiita
• Kune dzimwe nzvimbo dzakakora uye dzakakura, chimiro chisina mhango kana chimiro chine mbabvu dzakasimbiswa chinofanira kutorwa

Zvakanakira zveSand Casting process:
• Mutengo wakaderera nekuda kwekuchipa kwayo uye kudzokororwa mold zvinhu uye nyore kugadzira michina.
• Huremu hwakasiyana-siyana kubva pa0.10 kg kusvika pa500 kgs kana kutopfuura.
• Various Structure kubva nyore mhando kuti yakaoma mhando.
