Foornooyinka Vacuum waa qalab lagama maarmaan u ah warshadaha casriga ah. Waxay hirgelin kartaa habab adag oo aan lagu xallin karin qalabka kale ee kulaylka, kuwaas oo ah deminta vacuum iyo tempering, vacuum annealing, vacuum annealing, vacuum adag xal iyo waqti, vacuum sintering, vacuum daaweynta kulaylka kiimikada iyo hababka daahan vacuum. Heerkulka foornada waxay gaari kartaa ilaa 3000 ℃, tungsten iyo molybdenum waxay leeyihiin iska caabin heerkul sare oo wanaagsan iyo kororka fidinta kulaylka oo hooseeya, sidaa darteed waxaa badanaa loo isticmaalaa sida qalabyada foornada.
Guud ahaan, marka heerkulka foornada uu ka sarreeyo 1100 darajo Celsius, molybdenum ama tungsten waxaa loo tixgelin doonaa sida gaashaan kulaylka (oo ay ku jiraan muraayadaha dhinaca iyo muraayadaha sare iyo hoose): sida qaybaha kuleylka kuleylka ee foornada, doorka muhiimka ah ee molybdenum Shaashadda muraayadda tungsten iyo daboollada sare iyo kuwa hoose Saxanku waa inuu xannibaa oo dib u celinayaa kulaylka foornada. Saxanka dahaarka kulaylka tungsten iyo molybdenum guud ahaan waxa uu ka samaysan yahay jeexjeex, kaas oo la dami karo ama la is dulsaaran karo. Taariko la isku qurxiyo, baararka U-qaabeeya ama ilo silig molybdenum iyo spacers ayaa loo isticmaali karaa inta u dhaxaysa shaashadaha lakab kasta, waxaana lagu dhejiyaa silig molybdenum ama fiilooyinka tungsten iyo boolal.
