Vacuum castingsndi zigawo zachitsulo zomwe zimapangidwa ndindondomeko ya vacuum. Ndiosiyana ndi momwe amapangira ndalama chifukwa cha njira yomwe imagwiritsidwa ntchito popanga zitsulo izi. Njirayi imayamba ndikuyika nkhungu ya zidutswa ziwiri mu chipinda chopumuliramo. Kenako, vacuum imakokera chitsulo chosungunuka mu nkhungu. Potsirizira pake, kuponyerako kumalimbikitsidwa mu uvuni ndipo nkhungu imachotsedwa kuti atulutse zotsalira zomaliza.
Ngati muli ndi pulojekiti yomwe imafuna ma vacuum apamwamba kwambiri, titha kukupatsani. Pano ku RMC, timagwiritsa ntchito mphamvu yokoka komanso njira zopangira vacuum kuti tipange zojambula zomwe zimakhala zolemera kuyambira ma kilogalamu angapo mpaka mazana a kilogalamu. Zaka zambiri zomwe takumana nazo munjira zonsezi zimatsimikizira kuti titha kupereka zida zapamwamba kapena zapafupi zomwe zimafuna ntchito yomaliza kapena yomaliza.
▶ Zida Zoyatsira Vuto:
• Chitsulo cha Carbon: Chitsulo Chochepa cha Carbon, Medium Carbon Steel ndi High Carbon Steel kuchokera ku AISI 1020 kupita ku AISI 1060.
• Cast Steel Alloys: ZG20SiMn, ZG30SiMn, ZG30CrMo, ZG35CrMo, ZG35SiMn, ZG35CrMnSi, ZG40Mn, ZG40Cr, ZG42Cr, ZG42CrMo...etc popempha.
• Stainless Steel: AISI 304, AISI 304L, AISI 316, AISI 316L ndi kalasi ina yachitsulo chosapanga dzimbiri.
• Mkuwa & Mkuwa.
• Zida Zina ndi Miyezo pakupempha
▶ V Ntchito Yoyimba Njira:
• Kukula Kwambiri: 1,000 mm × 800 mm × 500 mm
• Kulemera kwake: 0,5 kg - 100 kg
• Mphamvu Zapachaka: matani 2,000
• Kulekerera: Popempha.
▶ Njira Zopangira Vuto:
• Chitsanzocho chimakutidwa mwamphamvu ndi pulasitiki yopyapyala.
• Botolo limayikidwa pamwamba pa pepala lophimbidwa ndipo limadzazidwa ndi mchenga wouma popanda kumanga.
• Flak yachiwiri imayikidwa pamwamba pa mchenga, ndipo vacuum imakoka mchenga kuti chithunzicho chikhale cholimba ndi kuchotsedwa. Magawo awiri a nkhungu amapangidwa ndikusonkhanitsidwa motere.
• Panthawi yothira, nkhunguyo imakhalabe pansi pa vacuum koma malo oponyera sakhala.
• Chitsulocho chikalimba, vacuum imazimitsidwa ndipo mchenga umagwa, ndikutulutsa kuponya.
• Kuumba vacuum kumapanga kuponya ndi tsatanetsatane wamtundu wapamwamba komanso kulondola kwenikweni.
• Ndiwoyenera makamaka pamapangidwe akulu, osalala.
