Cov txheej txheem ntawmhlau xuab zeb castingyuav tsum tau siv cov xuab zeb.Cov xuab zeb pwm yog siv los ua cov hlau.Tom qab cov txheej txheem casting, cov xuab zeb pwm raug tshem tawm.Qhov no tshem tawm cov qauv, uas tawm hauv kab noj hniav.Cov chaw sab hauv kuj tuaj yeem tsim los ntawm cov cores.Cov cam khwb cia no tuaj yeem loj lossis me.Cov no yog ua los ntawm hlau lossis txhuas.Nws cov txheej txheem tsim khoom sib txawv nyob ntawm seb hom hlau xav tau.

Cov txheej txheem ntawm hlau xuab zeb casting yuav tsum nchuav hlau molten rau hauv pwm kab noj hniav.Cov pwm no muaj ntau cov kab noj hniav, los yog risers.Txhawm rau kom txo qis qhov shrinkage thaum lub sij hawm solidification, txhua riser qhib.Thawj cov khoom uas nkag mus rau hauv lub pwm kab noj hniav dhau los ntawm kev qhib hauv lub riser.Tom qab ntawd cov pwm raug kaw, tawm hauv ib kab rau cov hlau molten.Thaum cov hlau txias, nws raug tso tawm los ntawm cov xuab zeb tawg.

Tom qab sau cov pwm kab noj hniav, cov xuab zeb pwm muab tso rau hauv ib lub thawv kom cov hlau molten ntws mus rau hauv. Cov hlau molten feem ntau yog hlau, hlau, tooj liab, tooj dag, magnesium, lossis txhuas alloys.Qee zaum, lwm yam khoom siv tau siv, xws li txhuas, tin, lossis zinc.Cov hlau molten tseem ci liab thiab hnyav dua li cov xuab zeb casting, ua rau cov casting ntab thiab tawg pwm.
