Kev xaiv txoj kev casting txoj cai yuav tsum muaj kev xav txog ntau yam xws li cov khoom siv casting, cov txheej txheem complexity, ntau lawm ntim, precision yuav tsum tau, thiab tus nqi tswj. Hauv qab no yog kev sib piv ntawm cov txheej txheem casting tseem ceeb thiab cov lus pom zoo xaiv:
Xaiv los ntawm Kev Tsim Nyog Volume
Ib thooj lossis me me batch ntau lawm: Sand casting yog pom zoo. Nws muaj cov nqi pwm tsawg, cov txheej txheem hloov tau yooj yim, thiab tsim nyog rau kev ua haujlwm- zoo li cov castings, dav siv hauv tshuab, tsheb, thiab lwm yam.
Ntau lawm: Tuag casting lossis hlau pwm casting yog nyiam. Txawm hais tias pwm peev yog siab, tus nqi ib thooj yog tsawg thiab efficiency siab, haum rau cov qauv txheem xws li automotive log hubs thiab cav brackets.
Kev xaiv los ntawm Casting Structure thiab Precision Requirements
Cov duab tsis yooj yim thiab ntau cov kab noj hniav sab hauv: Kev nqis peev casting (poob- siv quav ciab casting) raug pom zoo, ua tiav millimeter- qib precision, haum rau aerospace qhov chaw thiab cov cuab yeej ntsuas precision.
Nyias-walled los yog loj- loj castings: Tsawg-pressure casting yog superior, nrog du puv thiab ntom qauv, feem ntau yog siv rau cov khoom tseem ceeb xws li tsheb lub tog raj kheej taub hau thiab log hubs.
Tubular thiab nplhaib -zoo li tus castings:
Centrifugal casting yog txoj kev nyiam, vim nws tshem tawm qhov xav tau ntawm cov tub ntxhais thiab ua rau siab - ntom ntom castings, dav siv rau cov kav hlau cam khwb cia, lub tog raj kheej liner, thiab lwm yam.
Kev xaiv raws li cov khoom siv:
Aluminium alloys thiab magnesium alloys: tuaj yeem tuag-casting, qis-pressure casting, lossis hlau pwm casting, ntsuas qhov hnyav thiab lub zog xav tau.
Cam khwb cia hlau thiab cam khwb cia hlau: Feem ntau siv xuab zeb casting, tshwj xeeb tshaj yog haum rau cov workpieces loj xws li tshuab cuab tam txaj thiab valve lub cev.
High - kub alloys los yog cov ntaub ntawv tshwj xeeb: Nqus tuag casting los yog precision casting yog pom zoo kom txo oxidation thiab porosity tsis xws luag.
