Tuag casting yog txheej txheem hlau casting yam ntxwv los ntawm daim ntawv thov kev kub siab rau molten hlau nyob rau hauv lub pwm kab noj hniav. Cov pwm feem ntau yog machined los ntawm siab -lub zog alloys, thiab cov txheej txheem dais ib co zoo li txhaj tshuaj molding. Feem ntau cov tuag- nrum qhov chaw tsis yog-ferrous- xws li cov uas ua los ntawm zinc, tooj liab, txhuas, magnesium, lead, tin, thiab lawv cov alloys. Nyob ntawm seb hom kev tuag casting ua haujlwm li cas, yuav tsum muaj lub tshuab txias-chamber lossis kub-chamber tuag-casting tshuab.
Muab tus nqi siab ntawm cov cuab yeej casting thiab pwm, qhov tuag- txheej txheem casting feem ntau yog tshwj tseg rau kev tsim khoom loj ntawm cov khoom loj. Kev tsim cov khoom tuag- cov khoom pov tseg yog qhov ncaj ncaj, feem ntau tsuas yog muaj plaub kauj ruam tseem ceeb, uas ua rau cov nqi nce qis heev hauv ib chav. Kev tuag casting tshwj xeeb yog zoo- haum rau kev tsim cov ntim loj ntawm me me mus rau nruab nrab- qhov loj me; yog li ntawd, nws yog qhov siv dav tshaj plaws ntawm tag nrho cov txheej txheem casting. Piv rau lwm cov txheej txheem casting, tuag casting yields qhov chaw nrog smoother nto finishes thiab superior seem sib xws.
Ua raws li cov txheej txheem kev tuag- cov txheej txheem casting, ntau qhov kev hloov pauv siab tau tshwm sim. Cov no suav nrog "pore-dawb" tuag- txheej txheem casting, tsim los txo qhov tsis xws luag los ntawm kev tshem tawm cov porosity sab hauv; cov txheej txheem "kev txhaj tshuaj ncaj qha"- feem ntau yog siv rau zinc casting- uas txo cov khoom pov tseg thiab boosts yield tus nqi; thiab lwm yam txuj ci tshiab xws li cov txheej txheem "Accurad" (tsim los ntawm General Motors) thiab semi-cov khoom tuag casting.
