Casting complex qhov chaw, yog txheej txheem ntawm casting kom tau blanks, mus rau xuab zeb casting txheej txheem piav qhia, ua ntej ua cov seem ntawm cov ntoo pwm, qhov chaw nrog cam khwb cia qhov yuav tsum tau ua los ntawm ib tug av nkos core box rau kev tsim cov av nkos cores, thiab ces. lub thawv molding thiab av nkos core yog tsim los ntawm molding. Cov xuab zeb pwm tau muab faib ua rau sab sauv thiab qis. Cov pwm sab saud kuj yuav tsum tau siv rau kev nchuav sprue (hlau ua kua inlet) thiab riser (cua cua thiab hlau ua kua dej ntws). Tom qab lub pwm pwm tiav lawm, tshem tawm cov pwm pwm los ntawm lub pwm pwm, muab tso rau hauv cov av nkos core, kaw lub thawv, thiab ncuav cov kua hlau molten rau hauv cov kab noj hniav sib xws rau cov qauv ntawm cov khoom, kom txog rau thaum cov hlau ua kua. overflows los ntawm riser. Tom qab lub casting txias lawm, cov xuab zeb raug tshem tawm, cov xuab zeb raug tshem tawm, thiab cov hlau thaiv ntawm lub riser thiab lub rooj vag ntawm lub casting raug tshem tawm kom tau txais cov khoom seem. Tom qab dhau qhov kev tshuaj xyuas, nws feem ntau tuaj yeem xa mus rau kev ua haujlwm kho tshuab. Yog tias muaj cov kev xav tau tshwj xeeb, kev ua haujlwm kho tshuab tuaj yeem ua tiav yam tsis muaj kev kho mob laus.
