Alloy steel poob ua npuas ncauj castings yog cov hlau casting khoom cam khwb cia los ntawm ploj ua npuas ncauj casting txheej txheem. Poob Foam Casting (LFC), tseem hu ua Puv Pwm Casting, yog ib hom hlau ua txheej txheem nrog cov txheej txheem xuab zeb qhuav. EPC qee zaum tuaj yeem luv luv rau Expendable Pattern Casting vim tias cov qauv ua npuas ploj tuaj yeem siv ib zaug xwb. Tom qab cov qauv ua npuas ncauj tiav los ntawm cov tshuab tshwj xeeb, tom qab ntawd cov qauv yas foamed yog coated nrog refractory txheej los ua lub plhaub muaj zog kom tiv taus cov hlau molten. Cov qauv ua npuas ncauj nrog cov plhaub tau muab tso rau hauv lub thawv xuab zeb, thiab sau nrog cov xuab zeb qhuav nyob ib ncig ntawm lawv. Thaum lub sij hawm pouring, lub high-temperature molten hlau ua rau cov ua npuas ncauj qauv pyrolyzed thiab "poob" thiab occupies lub tawm kab noj hniav ntawm cov qauv, thiab thaum kawg cov tiav lawm xav castings yog tau.
