Cua teem xuab zeb casting yog cov txheej txheem tshwj xeeb uas tsis yog-ci molding uas siv cov tshuaj binders kho ntawm qhov kub thiab txias los tsim cov khoom siv high-precision, dimensionally ruaj khov hlau. Tsis zoo li cov xuab zeb ntsuab ib txwm siv los yog cov txheej txheem resin-bonded, cov txheej txheem huab cua tshem tawm qhov xav tau ntawm thermal curing ncu, tso cai rau kev tsim cov geometries loj, nrog cov txheej txheem zoo tshaj plaws thiab ua kom nruj dua. Txoj kev no yog tshwj xeeb tshaj yog muaj nuj nqis nyob rau hauv kev lag luam hnyav rau kev tsim OEM qhov chaw uas cov qauv kev ncaj ncees thiab qhov tseeb qhov tseeb yog qhov tseem ceeb, muab cov txiaj ntsig zoo rau cov khoom ntim qis-rau-nruab nrab khiav yam tsis muaj cov cuab yeej siv siab txuam nrog peev casting.
Dab tsi yog Air Set Sand Casting? Nkag siab txog Cov Txheej Txheem Tsis Muaj Ci
Cua teeb xuab zeb casting, feem ntau hu ua tsis muaj ci casting, sawv cev rau ib qho kev hloov pauv tseem ceeb hauv kev tsim tshuab. Lo lus "huab cua teeb" yog los ntawm qhov tseeb tias cov xuab zeb pwm teeb los yog hardens nyob rau hauv chav tsev kub los ntawm cov tshuaj tiv thaiv, tsis yog yuav tsum tau cua sov los yog compacting quab yuam ib leeg. Cov txheej txheem no txuas qhov sib txawv ntawm tus nqi qis, qis-precision ntsuab xuab zeb casting thiab tus nqi siab, siab-precision peev casting.
Nyob rau hauv txoj kev tsim no, silica xuab zeb yog tov nrog kua organic binder thiab ib tug catalyst. Thaum sib tov, cov xuab zeb tseem pliable rau lub sijhawm ua haujlwm luv luv, tso cai rau cov neeg ua haujlwm hauv tsev los ntim nws nyob ib ncig ntawm tus qauv. Raws li cov tshuaj tiv thaiv kev loj hlob, cov pwm hardens mus rau hauv ib tug nruj qauv muaj peev xwm ntawm withstanding lub siab ntawm molten hlau. Qhov tsis muaj thermal curing tsis tsuas yog txo lub zog noj xwb tab sis kuj txo qis thermal distortion hauv pwm, ua rau castings nrog qhov tshwj xeeb qhov ruaj khov.
Core Mechanism: Chemical Bonding tsis muaj cua sov
Qhov tseem ceeb sib txawv ntawm huab cua teeb thiab lwm txoj kev casting yog nyob rau hauv kev sib raug zoo mechanism. Hauv ntsuab xuab zeb casting, av nplaum thiab dej muab kev sib koom ua ke, uas tuaj yeem ua rau muaj kev cuam tshuam txog cov dej noo xws li roj porosity. Nyob rau hauv sib piv, cua teeb tshuab siv hluavtaws resins - feem ntau furan, phenolic, los yog alkyd-raws li polymerize raws li kev sib cuag nrog ib tug acid catalyst. Cov tshuaj tiv thaiv no muaj zog thiab thermally ruaj khov, kom ntseeg tau tias cov pwm tuav nws cov duab txawm tias raug kub hnyiab heev.
Cov txheej txheem tshuaj tua kab no tso cai rau kev tsim cov pwm nrog lub zog kub kub thiab qis qis. Rau cov kws tshaj lij thiab cov kws tshaj lij kev muag khoom, qhov no txhais tau tias tsawg dua machining nyiaj pub dawb thiab txo cov khoom pov tseg. Lub peev xwm los tswj lub sijhawm teeb tsa los ntawm kev kho qhov sib piv catalyst muab cov chaw tsim khoom nrog qhov yooj yim los tswj ob qho tib si me me, cov khoom sib txawv thiab cov khoom lag luam loj uas hnyav ntau tons.
Yuav Ua Li Cas Cua Teeb Sand Casting Ua Haujlwm: Step-by-Step Production Flow
Nkag siab txog kev ua haujlwm ntawm huab cua teeb xuab zeb casting yog qhov tseem ceeb rau kev ntsuas nws qhov tsim nyog rau cov haujlwm OEM tshwj xeeb. Cov txheej txheem yog txheej txheem thiab tso siab rau ntau qhov sib piv ntawm cov tshuaj lom neeg thiab cov neeg ua haujlwm txawj ua haujlwm. Hauv qab no yog cov ncauj lus kom ntxaws ntau lawm.
1. Kev npaj thiab txheej txheej
Cov txheej txheem pib nrog kev npaj cov qauv, uas tuaj yeem ua los ntawm ntoo, hlau, yas, lossis ua npuas dej. Txhawm rau kom tshem tawm tau yooj yim thiab du nto, tus qauv yog coated nrog tus neeg sawv cev sib faib. Cov kauj ruam no yog qhov tseem ceeb vim tias huab cua teeb xuab zeb yog nplaum ua ntej nws kho. Tus neeg saib xyuas kev tso tawm zoo tiv thaiv cov xuab zeb los ntawm kev ua raws li cov qauv, txo qhov kev pheej hmoo ntawm pwm puas thaum lub sij hawm stripping.
2. Xuab zeb sib tov thiab Binder Ntxiv
Silica xuab zeb yog pub rau hauv ib qho kev sib tov txuas ntxiv uas nws tau sib xyaw nrog cov kua binder thiab catalyst. Qhov sib tov yuav tsum tau ua kom zoo thiab sib xws kom ntseeg tau tias muaj zog pwm zoo ib yam. Qhov piv ntawm binder rau xuab zeb feem ntau yog li ntawm 1.0% mus rau 2.5%, nyob ntawm seb qhov yuav tsum tau muaj zog thiab hom hlau raug cam khwb cia. Kev sib xyaw ntau dhau tuaj yeem ua rau lub sijhawm ntxov, thaum sib xyaw ua ke ua rau muaj qhov tsis muaj zog hauv pwm.
3. Moulding thiab Compaction
Cov xuab zeb sib tov npaj tau muab tso rau hauv ib lub khob los yog ncaj qha mus rau lub rooj tsavxwm. Cov neeg ua haujlwm manually lossis mechanically ram cov xuab zeb nyob ib ncig ntawm tus qauv kom ntseeg tau tias qhov ntom ntom. Vim hais tias cov xuab zeb yog qhov kev teeb tsa tus kheej, tsis tas yuav tsum muaj kev sib txuam ntau dhau, uas txo cov kev ntxhov siab ntawm tus qauv. Rau qhov loj, cov pwm tuaj yeem ua rau hauv ntu (kho thiab rub) siv ntoo lossis hlau thav duab los txhawb cov xuab zeb uas tsis tau kho kom txog thaum nws tawv.
4. Kho thiab tshem tawm qauv
Thaum cov xuab zeb tau ntim lawm, nws yog sab laug los kho ntawm qhov kub thiab txias. Lub sij hawm kho nws txawv ntawm feeb mus rau teev, nyob ntawm seb cov chemistry siv thiab cov av noo nyob ib puag ncig. Tom qab pib txheej txheem, tus qauv yog ua tib zoo tshem tawm. Qhov tshwm sim pwm kab noj hniav yog qhov tsis zoo ntawm tus qauv qub. Nyob rau theem no, txhua qhov tsim nyog kho lossis kov-ups yog ua los ntawm cov kws tshaj lij nrhiav cov kws tshaj lij.
5. Kev sib dhos thiab Gating System Kev teeb tsa
Lub cope thiab luag ib nrab ntawm cov pwm yog sib sau ua ke. Lub rooj vag kaw lus, suav nrog sprues, khiav, thiab risers, raug txiav rau hauv cov xuab zeb los yog ua ntej siv cov ntawv luam tawm. Cov kab no coj cov hlau molten mus rau hauv kab noj hniav thiab tso cai rau cov pa roj kom dim. Kev tsim cov rooj tog kom zoo yog qhov tseem ceeb los tiv thaiv kev kub ntxhov thiab oxidation thaum lub sij hawm nchuav.
6. Pouring thiab txias
Molten hlau yog nchuav rau hauv pwm ntawm qhov ntsuas kub. Lub siab thermal stability ntawm huab cua teeb xuab zeb tiv thaiv kev yaig ntawm cov pwm phab ntsa, ua kom muaj kev huv huv. Tom qab pouring, lub casting yog tso cai kom txias thiab solidify tag nrho. Qhov qis qis qis hauv cov xuab zeb casting pab txo cov kev ntxhov siab hauv cov hlau.
7. Ntxig thiab ntxuav
Thaum txias, lub pwm yog sib cais (shakeout), thiab lub casting yog muab tshem tawm. Cov xuab zeb feem ntau tuaj yeem rov qab tau thiab rov siv dua tom qab rov kho dua. Lub casting tom qab ntawd ua tiav cov txheej txheem ntxuav xws li txhaj tshuaj blasting, sib tsoo, thiab txiav cov rooj vag thiab risers kom ua tiav qhov kawg ze-net zoo.

- Draft Angles: Txawm hais tias huab cua teeb xuab zeb tsis tshua muaj nplaum ntau dua li cov xuab zeb ntsuab, muab cov kaum sab xis me ntsis (1-3 degrees) ua kom yooj yim tshem tawm cov qauv thiab txo qhov kev pheej hmoo ntawm pwm puas.
- Core Support: Rau cov yam ntxwv sab hauv, xyuas kom muaj kev txhawb nqa txaus rau cov xuab zeb cores. Core prints yuav tsum tau tsim los tuav lub hauv paus ruaj ntseg nyob rau hauv qhov chaw thaum lub sij hawm pouring los tiv thaiv kev hloov.
- Machining Allowances: suav nrog cov nyiaj machining txaus rau ntawm qhov chaw tseem ceeb. Thaum huab cua teeb casting muaj qhov zoo ntawm qhov tiav, machining kom meej qhov ntev thiab tshem tawm qhov tsis zoo ntawm qhov chaw.
Environmental Considerations thiab Sustainability
Hauv 2026, kev ruaj khov yog qhov kev txhawj xeeb tseem ceeb rau kev tsim khoom. Cua teeb xuab zeb casting muaj ntau yam zoo ib puag ncig. Cov txheej txheem tsis muaj ci siv lub zog tsawg dua li cov xuab zeb ci, vim nws tshem tawm qhov xav tau ntawm qhov cub. Tsis tas li ntawd, qhov siab reclaim tus nqi ntawm cov xuab zeb txo cov khib nyiab pov tseg. Ntau cov binders niaj hnub no tau tsim los ua kom qis qis, txo qis ib puag ncig hneev taw ntawm kev lag luam foundry. Xaiv ib lub chaw tsim khoom nrog kev tswj hwm ib puag ncig zoo ua ke nrog cov hom phiaj kev lag luam ruaj khov.
