Cov cuab yeej casting thiab cov hlau tuag yog cov nqi siv nyiaj txiag loj thiab qhov no tsuas yog txo cov txheej txheem rau cov khoom ntim khoom loj. Siv cov khoom siv tuag casting yog yooj yim, uas tsuas yog plaub lub ntsiab lus tseem ceeb, uas ua rau qhov nqi qis rau ib yam khoom tsawg. Nws yog qhov zoo tshaj plaws rau ntau qhov chaw me me mus rau qhov nruab nrab me me, uas yog vim li cas tuag casting ua ntau castings dua lwm tus txheej txheem casting. Tuag castings yog ib qho zoo kawg nkaus ntawm qhov kawg ntawm qhov kawg (los ntawm casting cov qauv) thiab qhov sib xws.
