OEM mwambo zingalowe akuponya mankhwala a imvi chitsulo ndi spheroidal graphite (SG) ductile nodular kuponyedwa chitsulo ndi kutentha mankhwala, mankhwala pamwamba ndi CNC Machining utumiki.
Vacuum Casting imatchedwanso kuti Negative Pressure Seled Casting, Reduced Pressure Casting kapena V Process Casting. Vacuum kuthamanga kuponyera amafuna kugwiritsa ntchito zida mpweya m'zigawo kuchotsa mpweya mkati mwa nkhungu kuponyera, ndiyeno ntchito mavuto kusiyana mkati ndi kunja kwa nkhungu kuphimba mkangano pulasitiki filimu pa chitsanzo ndi Chinsinsi. Chikombole choponyera chidzakhala cholimba kuti chitha kupirira chitsulo chosungunula panthawi yoponya. Mukapeza nkhungu ya vacuum, lembani m'bokosi la mchenga ndi mchenga wowuma popanda binder, ndiyeno musindikize pamwamba pa nkhungu yamchenga ndi filimu yapulasitiki, ndikutsatiridwa ndi vacuum kuti mchenga ukhale wolimba komanso wolimba. Pambuyo pake, chotsani nkhungu, ikani mchenga, kutseka nkhungu kuti zonse zikonzekere kutsanulira. Potsirizira pake, kuponyedwa kumapezedwa pambuyo poti chitsulo chosungunula chizikhazikika ndikukhazikika.

Ductile cast iron, yomwe imatchedwanso nodular cast iron, spheroidal graphite cast iron kapena chitsulo cha SG mwachidule, imayimira gulu lachitsulo chonyezimira. Nodular kuponyedwa chitsulo amapeza nodular graphite kudzera spheroidization ndi inoculation mankhwala, amene bwino bwino makina katundu wa chitsulo chotayidwa, makamaka plasticity ndi kulimba, kuti apeze mphamvu apamwamba kuposa mpweya zitsulo.
Ma ductile iron castings ali ndi magwiridwe antchito abwinoko kuposa chitsulo cha kaboni, pomwe zopangira zitsulo za kaboni zimakhala zowotcherera bwino. Ndipo kumlingo wina, ma ductile iorn castings amatha kukhala ndi machitidwe oletsa kuvala ndi dzimbiri. Chifukwa chake kuponyera kwachitsulo kwa ductile kumatha kugwiritsidwa ntchito popangira nyumba zina zamapampu kapena makina operekera madzi. Komabe, tifunikabe kusamala kuti tipewe kuvala ndi dzimbiri.
Chitsulo chachitsulo sichinthu chimodzi koma ndi gawo la gulu la zipangizo zomwe zingathe kupangidwa kuti zikhale ndi katundu wambiri pogwiritsa ntchito microstructure. Chikhalidwe chodziwika bwino cha gulu ili la zipangizo ndi mawonekedwe a graphite. Muzitsulo za ductile, graphite imakhala ngati tinthu tating'onoting'ono osati ma flakes monga momwe ili muchitsulo chotuwa. Mawonekedwe akuthwa a ma flakes a graphite amapangitsa kuti pakhale kupanikizika mkati mwazitsulo zachitsulo komanso mawonekedwe ozungulira a tinthu tating'onoting'ono tochepa, motero amalepheretsa kupanga ming'alu ndikupereka ductility yowonjezera yomwe imapatsa aloyi dzina lake. Nthawi zambiri, ngati chitsulo cha ductile chingakwaniritse zomwe mukufuna, chitsulo cha ductile chikhoza kukhala chisankho chanu choyamba, m'malo mwa chitsulo cha carbon pakupanga kwanu.
