Kev tswj qhov kub thiab txias ntawm qhov tuag-casting pwm yog qhov tseem ceeb rau kev tsim cov khoom zoo- zoo- nrum qhov chaw. Cov pwm kub tsis sib xws los yog tsis tsim nyog tuaj yeem ua rau muaj qhov tsis txaus ntseeg hauv cov castings, deformation thaum lub sij hawm ejection, thiab tsis xws li thermal stress, sticking, depressions, shrinkage kab noj hniav, thiab kub npuas.
Cov pwm kub hloov pauv tseem ceeb kuj tuaj yeem cuam tshuam cov kev hloov pauv hauv lub voj voog ntau lawm, xws li lub sijhawm sau, lub sijhawm txias, thiab lub sijhawm txheej.
Thaum tsim cov tuag- cov khoom pov tseg, cov qauv tsim qauv yuav tsum tau muab tso ua ke. Yog tias cov qauv tsim cov kaum sab xis tsis muaj, cov txheej txheem txheej txheem yuav tsum tau muab qhov tsim nyog rau kev demolding. Cov kev taw qhia ntawm cov kaum sab xis no yuav tsum ua raws li cov kev taw qhia ntawm demolding ntawm lub casting.
