1- Sand Casting yog dab tsi?
Xuab zeb castingyog ib txwm ua tab sis kuj niaj hnub casting txheej txheem. Nws siv cov xuab zeb ntsuab (cov xuab zeb ntub) los yog cov xuab zeb qhuav los tsim cov txheej txheem molding. Cov xuab zeb ntsuab ntsuab yog cov txheej txheem qub tshaj plaws uas siv hauv keeb kwm. Thaum ua cov pwm, cov qauv ua los ntawm cov ntoo, hlau lossis yas yuav tsum tau tsim los ua cov kab noj hniav hollow. Cov hlau molten ces hliv rau hauv kab noj hniav los ua tuscastingstom qab txias thiab solidification. Xuab zeb casting tsis tshua kim dualwm yam txheej txheem castingob qho tib si rau pwm kev loj hlob thiab chav tsev casting ib feem.
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 pwm. Lawv muaj lawv tus kheej lub npe, xws liplhaub casting, furan resin coated xuab zeb casting (tsis muaj ci hom),poob ua npuas ncauj castingthiab nqus casting.
2 - Sand Castings Ua li cas?
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 (lossis qauv) uas yog compressed nrog cov xuab zeb thiab cov binder additives los tsim cov hlau castings kawg. 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 castings raug ntxuav thiab ua tiav rau cov khoom xa tuaj rau cov neeg siv khoom.
3 - Sand Casting siv rau dab tsi?
Xuab zeb castingsyog siv dav hauv antau hom kev lag luamthiab cov cuab yeej siv tshuab, tshwj xeeb tshaj yog rau cov castings loj tab sis nrog me me kom muaj nuj nqis. Vim tus nqi qis ntawm kev txhim kho cov cuab yeej thiab cov qauv, koj tuaj yeem nqis peev tus nqi tsim nyog hauv pwm. Feem ntau hais lus, cov xuab zeb casting yog thawj qhov kev xaiv rau cov tshuab hnyav xws li cov tsheb thauj khoom hnyav, tsheb thauj khoom thauj khoom, kev tsim kho tshuab, li qub, twj thiabhydraulic systems. Tshwj xeeb tshaj yog, covductile hlau xuab zeb castingstau siv ntau thiab ntau dua rau kev lag luam niaj hnub no.
4 - Qhov zoo ntawm Sand Casting yog dab tsi?
✔ Tus nqi qis dua vim nws pheej yig thiab siv tau cov khoom pwm thiab cov cuab yeej tsim khoom yooj yim.
✔ Ntau qhov hnyav ntawm chav tsev los ntawm 0.10 kg txog 500 kgs lossis loj dua.
✔ Ntau yam qauv los ntawm hom yooj yim mus rau hom complex.
✔ Haum rau kev tsim khoom ntawm ntau qhov ntau.
5 - Dab tsi Hlau & Alloys Ua Koj Cov Xuab Zeb Casting Foundry feem ntau nrum?
Feem ntau feem ntau cov hlau tsis muaj hlau thiab cov hlau tsis muaj hlau tuaj yeem raug pov los ntawm cov txheej txheem xuab zeb casting. Rau cov khoom siv ferrous,grey cam khwb cia hlau, cam khwb cia hlau , carbon hlau ,hlau alloy, cuab yeej steel nrog raustainless hlau alloysfeem ntau yog nchuav. Rau cov ntawv thov nonferrous, feem ntau Aluminium, Magnesium,Copper-based alloysthiab lwm yam ntaub ntawv nonferrous tuaj yeem raug pov, thaumAluminium thiab nws cov alloyyog qhov dav tshaj plaws ntawm cov xuab zeb casting.
6 - Dab tsi Casting Tolerances Koj Cov Sand Castings tuaj yeem ua tiav?
Cov kev kam rau ua tau muab faib ua Dimensional Casting Tolerances (DCT) thiab Geometrical Casting Tolerances (GCT). Peb lub tuam txhab xav tham nrog koj yog tias koj muaj kev thov tshwj xeeb ntawm qhov yuav tsum tau ua. Ntawm no yog cov hauv qab no yog cov qib tolerances uas peb tuaj yeem ncav cuag los ntawm pebntsuab xuab zeb casting, plhaub pwm casting thiab tsis-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
7 - Sand Moulds yog dab tsi?
Cov xuab zeb pwm txhais tau hais tias cov txheej txheem molding ua los ntawm cov xuab zeb ntsuab lossis cov xuab zeb qhuav. Cov xuab zeb moulding tshuab feem ntau npog lub thawv xuab zeb, spures, ingates, risers, xuab zeb cores, pwm xuab zeb, binders (yog tias muaj), cov ntaub ntawv refractory thiab tag nrho lwm yam tuaj yeem pwm seem.
