Tuag-casting pwm yog ib qho cuab yeej siv los cam khwb cia hlau Cheebtsam ntawm ib tug tshwj xeeb tuag-casting tshuab. Cov txheej txheem tuag yooj yim- casting txheej txheem cuam tshuam nrog kev txhaj tshuaj molten hlau rau hauv pwm kab noj hniav ntawm qhov qis lossis siab ceev; cov pwm nta ib qho chaw txav tau yooj yim uas siv lub siab thiab forging ua raws li cov hlau txias. Cov txheej txheem no tsis tsuas yog tshem tawm qhov tsis xws luag xws li shrinkage kab noj hniav thiab porosity tab sis kuj hloov cov microstructure sab hauv mus rau hauv lub xeev forged tus yam ntxwv los ntawm kev ua kom zoo, tawg - cov nplej, yog li txhim kho qhov zoo ntawm cov khoom siv tag nrho.
Tuag-cov ntaub ntawv pov thawj, tuag- cov cav tov, thiab cov pwm ua peb qhov tseem ceeb ntawm kev tuag- casting ntau lawm; tsis muaj leej twg tuaj yeem faib nrog. Kev tuag- txheej txheem casting entails kev sib xyaw ua ke ntawm peb lub ntsiab lus los tsim- nyob rau hauv ib qho chaw ruaj khov, sib dhos, thiab ua haujlwm tau zoo- tsim nyog (lossis txawm tias hwm- zoo) castings uas ua tau zoo hauv ob qho tib si saum npoo thiab sab hauv zoo, thaum ua tau raws li txhua qhov kev qhia tshwj xeeb uas tau teev tseg hauv daim phiaj xwm lossis kev pom zoo.
