Xuab zeb casting siv cov xuab zeb ntsuab (cov xuab zeb ntub) los yog cov xuab zeb qhuav los tsim cov txheej txheem molding. Covntsuab xuab zeb castingyog cov txheej txheem casting qub tshaj plaws siv hauv keeb kwm. Thaum ua cov pwm, cov qauv ua los ntawm cov ntoo los yog hlau yuav tsum tau tsim nyob rau hauv thiaj li yuav tsim lub hollow kab noj hniav. Cov hlau molten ces hliv rau hauv kab noj hniav los tsim cov castings tom qab txias thiab solidification. Xuab zeb casting tsis tshua kim dua li lwm cov txheej txheem casting ob qho tib si rau kev tsim pwm thiab chav ua haujlwm casting. Cov xuab zeb casting, ib txwm txhais tau tias ntsuab xuab zeb casting (yog tias tsis muaj lus piav qhia tshwj xeeb). Txawm li cas los xij, niaj hnub no, lwm cov txheej txheem casting kuj tseem siv cov xuab zeb los ua cov pwm. Lawv muaj lawv tus kheej lub npe, xws liplhaub molding, furan resin coated xuab zeb casting (tsis muaj ci hom),poob ua npuas ncauj castingthiab nqus casting.
Peb muaj ntau hom casting rau koj xaiv. Ib feem ntawm cov txheej txheem xaiv rau koj qhov project yuav yog qhov kev xaiv ntawm cov txheej txheem casting uas yuav pab tau koj cov kev xav tau zoo tshaj plaws. Daim ntawv nrov tshaj plaws yog xuab zeb casting uas koom nrog ua ib qho kev ua tiav ntawm ib daim ntawv tiav (los yog qauv) uas yog compressed nrog xuab zeb thiab binder additives los ua qhov kawg casting. Cov qauv raug tshem tawm tom qab cov pwm los yog lub tswv yim tau tsim, thiab cov hlau yog qhia los ntawm lub tshuab khiav mus rau hauv cov kab noj hniav. Cov xuab zeb thiab cov hlau yog sib cais thiab cov casting ntxuav thiab tiav rau cov khoom xa tuaj rau cov neeg siv khoom.
Sand Casting VS Plhaub Pwm Casting:
Ob lub xuab zeb casting thiab plhaub pwm casting siv cov xuab zeb los ua lub hollow kab noj hniav rau pouring. Qhov txawv yog tias xuab zeb casting siv cov xuab zeb ntsuab los yog cov xuab zeb qhuav (poob ua npuas ncauj casting thiab lub tshuab nqus tsev casting siv cov xuab zeb qhuav los ua pwm), thaum lub plhaub pwm casting siv cov resin coated xuab zeb los ua cov txheej txheem molding. Cov xuab zeb coated tsis tuaj yeem rov siv dua. Txawm li cas los xij, lub plhaub pwm castings muaj ntau yam zoo dua li ntawmxuab zeb castings.
Sand Casting VS Peev Casting:
Ob txheej txheem casting no txawv ntawm cov khoom siv molding siv los ua cov qauv.Kev nqis peev castingsiv cov quav ciab los tsim cov khoom siv quav ciab (yog vim li cas nws tseem hu ua ploj wax casting) uas muaj qhov loj thiab qhov ntev raws li qhov xav tau castings. Tom qab ntawd cov khoom siv quav ciab yuav coated nrog cov xuab zeb thiab cov ntaub ntawv khi (feem ntau yog silica sol lossis iav dej) los tsim lub plhaub muaj zog rau cov hlau molten. Thaum lub sij hawm, cov xuab zeb casting feem ntau yog siv cov xuab zeb ntsuab los yog cov xuab zeb qhuav los ua cov kab noj hniav hollow, uas muaj tib qhov loj thiab qhov ntev raws li qhov xav tau casting qhov chaw. Rau ob qho tib si xuab zeb casting thiab peev casting txheej txheem, cov xuab zeb thiab siv quav ciab tuaj yeem rov siv dua. Cov peev txheej castings feem ntau muaj qhov zoo dua, geometrical thiab qhov tseeb qhov tseeb dua li cov xuab zeb castings.
Qhov kev tolerances yog muab faib ua Dimensional Casting Tolerances (DCT) thiab Geometrical Casting Tolerances (GCT). Peb qhov chaw tsim khoom xav nrog koj tham yog tias koj muaj kev thov tshwj xeeb ntawm qhov yuav tsum tau ua. Ntawm no nyob rau hauv cov nram qab no yog cov kev tolerances qib peb tuaj yeem ncav cuag los ntawm peb cov xuab zeb ntsuab, plhaub pwm casting thiab tsis muaj ci furan resin xuab zeb casting:
✔ DCT Qib los ntawm Green Sand Casting: CTG10 ~ CTG13
✔ DCT Qib los ntawm Plhaub Pwm Casting lossis Furan Resin Sand Casting: CTG8 ~ CTG12
✔ GCT Qib los ntawm Green Sand Casting: CTG6 ~ CTG8
✔ GCT Qib los ntawm Plhaub Pwm Casting lossis Furan Resin Sand Casting: CTG4 ~ CTG7
Qhov zoo ntawm Sand Casting txheej txheem
1- Tus nqi qis vim nws pheej yig thiab siv tau cov khoom pwm thiab cov khoom siv yooj yim.
2- Ntau qhov hnyav ntawm chav tsev los ntawm 0.10 kg txog 500 kgs lossis loj dua.
3- Ntau yam qauv los ntawm hom yooj yim mus rau hom complex.
4- Haum rau kev tsim khoom ntawm ntau qhov ntau.
