Shuruudaha Habaynta Vacuum Casting
• Ku isticmaal mashiinka shubista faakuumka.
• Kuleyli caaryada 70°C (doorbidayaa caaryada silikon polyaddition).
• Labada qayboodba ku kululee 20°C haddii ay dhacdo kaydinta heerkul hoose.
• Ku miisaan qaybta A ee koobka sare (ha iloobin inaad u ogolaato qashinka haraaga koobka).
• Ku miisaan qaybta B ee koobka hoose (koobka isku dhafka ah).
• Ka dib marka ay soo degto 10 daqiiqo hoosta faakuumka ku shub qaybta A ee qayb B oo ku qas 1 daqiiqo 30 ilaa 2 daqiiqo.
Ku rid caaryada silikoonka, oo markii hore lagu kululeeyay 70°C.
• Ku rid foornada ugu yaraan 70°C.
• Waxay ku kicisaa 45 daqiiqo ka dib at 70°C.
• Samee daawaynta kulaylka ee soo socota: 3 saac at 70°C + 2 saac at 80°C iyo 2hr at 100°C.
• Had iyo jeer markaad daaweynayso, dhig qaybta istaag.
Wax ka qabashada taxaddarrada
Taxadarrada caadiga ah ee caafimaadka iyo badbaadada waa in la ilaaliyaa marka la qabanayo alaabtan:
• Hubi hawo wanaagsan
• xidho galoofyada iyo muraayadaha badbaadada
Wixii macluumaad dheeraad ah, fadlan la tasho xaashida xogta badbaadada alaabta.
