Thaum xaiv cov txheej txheem tsim khoom rau precision alloy steel Cheebtsam, engineers feem ntau soj ntsuampeev castingthiabploj wax castingraws li kev sib tw daws teeb meem. Thaum cov ntsiab lus no nquag siv sib hloov, kev sib txawv me ntsis hauv cov txheej txheem thiab daim ntawv thov tuaj yeem cuam tshuam rau cov khoom zoo, nqi, thiab kev ua haujlwm.
1. Txheej txheem txheej txheem
Kev nqis peev Casting (Ceramic Plhaub txheej txheem)
● Sivmulti- txheej ceramic plhaub pwmua nyob ib ncig ntawm wax qauv
● Feem ntau ua haujlwmautomated slurry dippingrau pwm tsim
● Lub zog pwm ntau dua tso cai rau cov khoom loj dua (txog 100+ kg)
● Txheem kam rau ua:± 0.005 hli (ISO CT6-CT7)
Poob Wax Casting (Traditional Method)
● Cia siab rauib zaug - siv plaster lossis ceramic pwm
● Feem ntau sivphau ntawv siv quav ciab qauv sib dhos
● Zoo haum rau qhov me me (<25 kg) and intricate details
● Txheem kam rau ua:± 0.003 hauv / hauv (ISO CT5-CT6)
Key Kev nkag siab:Thaum tag nrho cov peev casting siv cov ntsiab lus ploj lawm, tsis yog tag nrho cov poob ciab casting ua tau raws li kev lag luam peev casting qauv.
2. Cov Khoom Siv Ua Haujlwm rau Alloy Steels
| Parameter | Kev nqis peev Casting | Poob Wax Casting |
|---|---|---|
| Nto tiav | Ra 125-250 µin (3.2-6.3 μm) | Ra 63-125 µin (1.6-3.2 μm) |
| Yam tsawg kawg ntawm phab ntsa Thickness | 1.5 hli | 0.8mm ib |
| Grain Structure | Kev taw qhia solidification | Equiaxed nplej |
| Common Steel Qib | 4140, 8620, 17-4PH | 316L, 304, 420 stainless hlau |
Technical Note:Peev casting's ceramic shells pab kom zoo dua kub tswj rausiab - carbon alloy steels, txo kub tearing txaus ntshai.
3. Kev txheeb xyuas tus nqi
Cov nqi siv cuab yeej:
● Kev nqis peev casting: $5,000-$20,000 (automated pattern tree)
● Poob wax casting: $1,000-$5,000 (manual pattern setup)
Ib -Unit Cov Nqi (Piv txwv: 100mm Steel Gear):
● Kev nqis peev: $18-35/unit (1,{2}} pcs)
● Poob Wax: $25-50/unit (100-500 pcs)
Txhaum-Kawm Point:~ 750 units nyiam peev casting rau alloy steels
4. Kev lag luam-Cov lus qhia tshwj xeeb
Xaiv Peev Casting Thaum:
✔ Ua tau siab - cov khoom muaj zog (piv txwv li, turbine hniav)
✔ Yuav tsum tau tshaj tawm -kev kho cua sov (quenching & tempering)
✔ Manufacturing larger parts (>10 kg)
Opt for Poob Wax Casting Thaum:
✔ Ua me me, complex kho mob / kho hniav qhov chaw
✔ Siv corrosion-cov hlau tsis muaj zog (cov ntsiab lus qis dua)
✔ Xav tau cov qauv qauv sai dua
5. Txoj Kev Tawm Tsam Hybrid
Niaj hnub nimno foundries tam sim no muab ob txoj kev:
1. 3D- luam tawm wax qauv nrog ceramic plhaub peev
2. Lub tshuab nqus tsev- pab poob ciab rau qhov tseem ceeb hauv aerospace
3. Ceev nrooj peev casting siv cov cores soluble
Ua Kev Xaiv Zoo
Rau siab -ntaus alloy steel ntau lawm, peev casting feem ntau muab cov khoom siv zoo dua thiab cov nqi ua haujlwm zoo. Txawm li cas los xij, tsawg- daim ntawv thov cov ntaub ntawv muaj tseeb tuaj yeem tau txais txiaj ntsig los ntawm cov khoom siv uas ploj lawm cov peev txheej nthuav dav.
Wabon Precision Metal muab ob qho tib si txheej txheem nrog cov khoom siv -kev ua kom zoo rau tshwj xeeb rau:
● ASTM A217/A352 siab-muaj cov khoom
● AMS 5382 siab -cov khoom kub
● Kev cai alloy kev tsim kho
[ Hu rau peb cov engineers] rau kev tshawb xyuas cov txheej txheem dawb raws li koj qhov kev kos duab kos duab thiab kev ua haujlwm.
