Cast Alloy Steel Draft Gear Housing for Railroad Freight Car

China OEM mwambo vacuum kuponyera zida zosinthira njanji katundu magalimoto a Cr-Mo aloyi zitsulo ndi kutentha kutentha, mankhwala pamwamba ndiCNC Machining utumiki.

Vacuum Casting imatchedwanso kuti Negative Pressure Seled Casting, Reduced Pressure Casting kapenaV 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 kumapezeka pambuyo poti chitsulo chosungunula chizikhazikika ndikukhazikika.

Kodi Ubwino Wa Vacuum Casting Ndi Chiyani?
1) Thevacuum castingskukhala ndi mawonekedwe olondola kwambiri, mawonekedwe omveka bwino komanso malo osalala.
2) Palibe zomangira, madzi ndi zowonjezera mumchenga woumba, zomwe zimapangitsa kuti mchenga ukhale wosavuta.
3) Ndikosavuta kuyeretsa ma vacuum castings. Mipweya yocheperako imapangidwa panthawi yoponya.
4) Zida zoponyera vacuum zitha kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Itha kugwiritsidwa ntchito popanga gulu laling'ono lachidutswa chimodzi komanso kupanga misa, makamaka ma castings akulu ndi apakatikati ndi ma castings okhala ndi mipanda yopyapyala ndioyenera kuponya vacuum.

Ndi Zitsulo ndi Zosakaniza Ziti Zomwe Zingathe Kuponyedwa ndi Vuto la Vacuum Casting?
• Iron Grey Cast, Ductile Cast Iron
• Carbon Steel: Low carbon, medium carbon and high carbon steel
•Cast Steel Alloys: Chitsulo chochepa cha alloy, chitsulo chapamwamba kwambiri, chitsulo chapadera cha alloy
• Aluminiyamu ndi ma aloyi awo
• Mkuwa & Mkuwa.

Chitsulo choponyera chimatanthawuza chitsulo chomwe chimagwiritsidwa ntchito popanga zitsulo. Chitsulo choponyedwa chiyenera kugwiritsidwa ntchito pamene mphamvu ya kuponyera ndi yokwera kwambiri ndipo kugwiritsa ntchito chitsulo chosasunthika sikungakwaniritse zofunikira. Komabe, kusungunuka kwachitsulo chosungunula chachitsulo chosasunthika sichofanana ndi chachitsulo chosungunuka, kotero makulidwe a kapangidwe kakutsanulira sikuyenera kukhala kochepa kwambiri ndipo mawonekedwewo asakhale ovuta kwambiri. Pamene silicon zili kulamulidwa pa malire apamwamba, fluidity wa chitsulo chosungunuka akhoza bwino.Kutaya zitsulo akhoza kugawidwa mu kuponyedwa aloyi zitsulo ndi kuponyedwa zitsulo mpweya malinga zikuchokera mankhwala, komanso akhoza kugawidwa mu kuponyedwa chida zitsulo, kuponyedwa chitsulo chapadera, zomangamanga ndi structural kuponyera ndi kuponyedwa aloyi zitsulo malinga ndi makhalidwe ake.

Chitsulo cha aloyi chikhoza kugawidwa kukhala chitsulo chochepa cha alloy (chinthu chonse cha aloyi ndi chocheperapo kapena chofanana ndi 5%), chitsulo chosungunuka (chinthu chonse cha aloyi ndi 5% mpaka 10%) ndikuponyera chitsulo cha aloyi (chinthu chonsecho zinthu ndi zazikulu kuposa kapena zofanana 10%).
