Tuag castings yog cov khoom hlau tsim los ntawm kev siv cov txheej txheem siab casting. Kuj tseem hu ua tuag- nrum qhov chaw lossis lub siab castings, lawv feem ntau yog tsim los ntawm cov ntaub ntawv xws li tooj liab, zinc, txhuas, thiab txhuas alloys. Cov txheej txheem no siv lub zog siab los txhaj cov hlau molten rau hauv pwm rau kev tsim sai, ua rau muaj kev ua haujlwm siab, ua kom tiav zoo, thiab cov nyiaj siv me me. Tus tsim yuav tsum xav txog yam xws li phab ntsa thickness, casting fillets, thiab cov kaum sab xis. Raws li cov khoom siv, tuag casting tuaj yeem muab faib ua cov kub chamber tuag casting tshuab (tsim rau zinc thiab magnesium alloys) thiab txias chamber tuag casting tshuab (tsim rau txhuas thiab tooj liab alloys). Nyob rau hauv kub chamber tuag casting, qhov kev txhaj tshuaj yog immersed nyob rau hauv molten hlau.
Tuag castings yog dav siv nyob rau hauv automotive qhov chaw, cav kav, motor kawg caps, thiab lwm yam teb. High- tshuab nqus tsev tuag casting tshuab tuaj yeem txo qhov porosity thiab txhim kho weldability thiab kev kho cua sov, ua lub luag haujlwm tseem ceeb hauv kev sib xyaw tuag casting ntawm lub zog tshiab. Siab-siab casting siv 15-100MPa siab los txhaj rau hauv pwm, tso cai rau aluminium alloy qhov chaw nrog phab ntsa thicknesses nyias li 0.5mm, haum rau cov khoom xws li cav thaiv. Nqus tuag casting nce ceev los ntawm kev tshem tawm huab cua los ntawm pwm kab noj hniav; thaum cov cuab yeej siv nyiaj ntau dua, cov txiaj ntsig mus ntev yog qhov tseem ceeb.
