Vacuum castingsndiwo nhengo dzesimbi dzinogadzirwa nevacuum casting process. Iwo akasiyana neakajairwa ekudyara castings nekuda kwehunyanzvi hunoshandiswa kugadzira idzi simbi zvidimbu. Nzira yacho inotanga nekuisa mold yezvidimbu zviviri muimba yevacuum. Vacuum yacho inobva yakwevera simbi yakanyungudutswa muforoma. Pakupedzisira, kukanda kunosimbiswa muhovhoni uye mold inobviswa kuitira kusunungura kukanda kwekupedzisira.
Kana iwe uine chirongwa chinoda emhando yepamusoro vacuum castings, tinogona kukupa iwo. Pano paRMC, isu tinoshandisa ese ari maviri giravhiti akadyiswa uye vacuum yekukanda nzira kugadzira tsika castings iyo inosiyana nehuremu kubva pamakirogiramu mashoma kusvika kumazana emakirogiramu. Makore edu asingaverengeki echiitiko mune mbiri idzi nzira dzinovimbisa kuti tinokwanisa kupa yepamusoro kana pedyo net mambure maumbirwo ayo anoda shoma kana kusapedza basa.
▶ Vacuum Casting Materials:
• Carbon Steel: Low Carbon Steel, Medium Carbon Steel uye High Carbon Steel kubva kuAISI 1020 kusvika kuAISI 1060.
• Cast Steel Alloys: ZG20SiMn, ZG30SiMn, ZG30CrMo, ZG35CrMo, ZG35SiMn, ZG35CrMnSi, ZG40Mn, ZG40Cr, ZG42Cr, ZG42CrMo...etc pakukumbira.
• Stainless Steel: AISI 304, AISI 304L, AISI 316, AISI 316L uye imwe giredhi resimbi isina tsvina.
• Brass & Copper.
• Zvimwe Zvishandiso neMitemo pakukumbira
▶ V Maitiro eKukanda Mano:
• Kukura Kwepamusoro: 1,000 mm × 800 mm × 500 mm
• Weight Range: 0.5 kg - 100 kg
• Kwegore Kukwanisa: 2,000 matani
• Kushivirira: Pakukumbira.
▶ Matanho ekukanda kweVacuum:
• Chimiro chakavharwa zvakasimba nepepa rakatetepa repurasitiki.
• Flask inoiswa pamusoro pepateni yakavharwa uye inozadzwa nejecha rakaoma pasina kusunga.
• Yechipiri flaki inobva yaiswa pamusoro pejecha, uye vacuum inokwevera jecha kuitira kuti pateni igare yakasimba uye ibudiswe. Mahafu maviri e mold anogadzirwa uye anounganidzwa nenzira iyi.
• Panguva yekudira, mold inoramba iri pasi pevacuum asi iyo yekukanda haidaro.
• Kana simbi yaoma, vacuum inodzimwa uye jecha rinodonha, richisunungura kukanda.
• Vacuum molding inoburitsa kukanda nehupamhi hwemhando yepamusoro uye nechiyero chedimensional.
• Yakanyatsokodzera mahombe, akati sandarara.

▶ Nei Iwe Uchisarudza RMC yeV (Vacuum) Maitiro Ekukanda Zvikamu?
• Kudzoreredza nyore kwejecha nekuti mabhainda haashandiswi
• Jecha haridi kugadziridzwa kwemagetsi.
• Kupinda kwemhepo kwakanaka nekuti hakuna mvura inosanganiswa nejecha, nokudaro kushomeka kwekukanda.
• Zvakanyanya kufanira kune hombe chiyero castings
• Mutengo unoshanda, kunyanya kune yakakura castings.
