Haina OEM ritenga ductile maka rino castings engaro te wax haumi makanga tukanga. Te rino ductile, e mohiotia ana ko te rino ductile cast, te rino nodular, te rino graphite spheroidal, te rino graphite spheroidal, te rino SG noa ranei mo te poto.Ina he matūriki iti, he porowhita, he pai te tohatoha o te kauwhata, he iti noa iho te ngoikoretanga, ka nui ake te ngohe o nga rino maka. Ko tenei momo rino ka kiia ko te rino ngongo, te rino nodular, te graphite porowhita ranei, te rino SG noa ranei. Ka taea tenei ahua o te kauwhata ma te taapiri i te konupora huānga, te cerium ranei te whakakotahitanga o nga huānga e rua ki te whakarewa rino. Ka taapirihia te konupora ki te rahinga o te 0.07 ki te 0. 10% ka whai i te taapiri o te ferro-silicon hei whakatairanga i te whakairoiro. I te wa e whakakoi ana, ka awhina te konupora ki te tohatoha kauwhata puta noa i te whakarewa.
He pai ake te kaha-ki-taimaha o te rino ductile, he pai ake te mahi miihini me te uara paanga teitei ake. I tua atu, ko nga waahanga rino ductile ka hangaia ma te mahi makanga ka taea te pai ake te whakahaere i te ahua o te waahanga ka whakatauritea ki te whakaheke i te hanga. No reira, he maha nga waahanga penei i nga rakau crank me nga rakau hono i te nuinga o te wa ka mahia e te takahanga takai kei te whakakapihia e te whakarewa rino.
