Poob pwm casting (poob ua npuas ncauj txheej txheem (Tebchaws USA), policast txheej txheem (Ltalis)) yog ua los ntawm cov yas ua npuas ncauj (EPS, STMMA los yog EPMMA) cov khoom siv polymer rau hauv cov pwm pwm nrog tib tus qauv thiab loj raws li qhov yuav tsum tau cam khwb cia. Tom qab dipping refractory xim (kom ntxiv dag zog, du thiab breathable) thiab ziab, nws yog faus rau hauv qhuav quartz xuab zeb los ntawm peb-seem kev co qauv. Lub thawv molding xuab zeb yog nchuav rau hauv cov kua hlau molten nyob rau hauv qhov tsis zoo, kom cov khoom siv polymer yog rhuab thiab gasified tawm, thiab ces hloov los ntawm cov kua hlau tom qab txias thiab solidification.
Piv nrog rau cov cuab yeej siv niaj hnub casting, qhov poob pwm casting muaj cov yam ntxwv hauv qab no: 1, casting zoo, tsis muaj nqi; 2, cov khoom siv tsis txwv, qhov loj yog tsim nyog; 3, siab precision, du nto, txo kev tu, txuag tshuab; 4, cov teeb meem sab hauv raug txo qis heev, lub koom haum casting yog ntom; 5, tuaj yeem ua tiav qhov loj, ntau lawm; 6, haum rau ntau lawm casting ntawm tib castings; 7, tsim nyog rau kev siv phau ntawv thiab kev tswj cov kab ntau lawm; 8. Lub xeev ntawm cov kab ntau lawm ua tau raws li cov kev cai ntawm kev tiv thaiv ib puag ncig; 9, tuaj yeem txhim kho qhov chaw ua haujlwm thiab kev tsim khoom ntawm cov kab ntau lawm, txo kev siv zog, txo kev siv zog.
