Cov xuab zeb casting thiab peev casting yog ob lub ntsiab casting txheej txheem hauvniaj hnub foundries. Ob qho tib si ntawm ob txoj kev casting no muaj lawv tus kheej cov yam ntxwv, qhov zoo thiab qhov tsis zoo. Covxuab zeb castingsiv cov xuab zeb ntsuab lossis cov xuab zeb qhuav los ua cov pwm ua ntej nchuav. Ua ntej cov pwm tsim, cov qauv ntoo, yas lossis hlau yuav tsum tau tsim ua ntej ua cov kab noj hniav ntawm cov xuab zeb pwm. Cov xuab zeb ntsuab thiab cov xuab zeb qhuav tuaj yeem rov siv dua tom qab casting thiab co tawm.
Thaumpeev casting, ib daim duab los yog replica yog tsim (feem ntau yog tawm ntawm wax) thiab muab tso rau hauv ib lub tog raj kheej hlau hu ua lub hwj. ntub plaster yog poured rau hauv lub tog raj kheej nyob ib ncig ntawm lub wax zoo. Tom qab lub plaster tau hardened, lub tog raj kheej uas muaj cov qauv siv quav ciab thiab plaster yog muab tso rau hauv ib lub kiln thiab yog rhuab kom txog thaum lub wax tau tag nrho vaporized. Tom qab cov wax tau tag nrho burnt-tawm (de-waxing), lub hwj yog muab tshem tawm los ntawm lub qhov cub, thiab molten hlau (feem ntau alloy hlau, stainless hlau, tooj dag ... Thaum cov hlau tau txias thiab solidified, plaster yog chipped, thiab cov hlau casting tshwm sim.
Casting yog qhov tseem ceeb heev rau kev tsim cov khoom sculptural los yog engineering duab nrog complex geometry hauv hlau. Cov khoom pov thawj muaj qhov tshwj xeeb zoo rau lawv, sib txawv heev ntawmmachined qhov chaw. Qee cov duab uas yuav nyuaj rau tshuab tau yooj yim dua. Kuj tseem muaj cov khoom pov tseg tsawg dua rau feem ntau cov duab, vim tsis zoo li machining, casting tsis yog cov txheej txheem rho tawm. Txawm li cas los xij, qhov tseeb ua tiav los ntawm kev casting tsis zoo li machining.
Thaum twg koj yuav tsum xaiv Peev Casting thiab Thaum twg Koj Yuav Tsum Xaiv Sand Casting?
Ib qho txiaj ntsig loj ntawm peev casting yog tias nws tuaj yeem tso cai rau undercuts hauv cov qauv, thaum xuab zeb casting tsis. Hauv cov xuab zeb casting, tus qauv yuav tsum tau rub tawm ntawm cov xuab zeb tom qab nws tau ntim, whereas hauv peev casting tus qauv yog vaporized nrog tshav kub. Hollow castings thiab thinner seem tuaj yeem ua tau yooj yim dua nrog kev nqis peev casting, thiab kev ua tiav zoo dua feem ntau ua tiav. Ntawm qhov tod tes, peev casting yog txheej txheem ntau dua raws sijhawm thiab kim, thiab tuaj yeem muaj qhov ua tiav qis dua li cov xuab zeb casting vim tias muaj ntau cov kauj ruam hauv cov txheej txheem thiab ntau lub sijhawm rau tej yam tsis raug.
