Los ntawm cov duab kos uas koj muab, qhov no yog cov khoom lag luam poob ua npuas ncauj, cov khoom lag luam yog qhov nyuaj dua piv nrog cov khoom ntim EPS li niaj zaus, thiab nrog cov txheej txheem tsis siv neeg EPS zoo moulding tshuab, filling thiab demolding yuav muaj teeb meem. Yog li peb xav txog cov khoom no thov semi-automatic puab molding tshuab los tsim nws.
EPS poob ua npuas ncauj casting pwm yog ib hom pwm siv hauv cov txheej txheem ua npuas ncauj ploj los ua cov khoom ua npuas ncauj. Cov pwm yog ua los ntawm EPS ua npuas ncauj, uas yog coated nrog ib tug refractory khoom. Tom qab ntawd, cov qauv ua npuas dej yog muab tso rau hauv ib lub hwj, thiab cov xuab zeb tau ntim ib ncig ntawm nws. Cov hlau molten yog nchuav rau hauv lub khob, uas vaporizes tus qauv ua npuas ncauj thiab hloov nws nrog cov hlau. Qhov tshwm sim yog cov khoom siv hlau nyuaj nrog cov ntsiab lus sib txawv uas yuav nyuaj rau kev ua tiav siv cov txheej txheem casting ib txwm.
