Sand casting manufacturing tseem yog txoj kev siv nyiaj ntau tshaj plaws rau kev tsim cov khoom siv hlau, tshwj xeeb tshaj yog thaum cov phab ntsa tuab tshaj 6 hli, qhov hnyav tshaj 5 kg, lossis txhua xyoo ntim ntawm 10 thiab 500 units. Tab sis tsis yog tag nrho cov xuab zeb casting yog sib npaug. Peb tau pom ntau tus neeg muas zaub tau txais castings nrog cov qauv tsis sib xws, qhov kev xav tau poob qis hauv cov kabmob flanges, lossis qhov loj me tom qab kev kho cua sov - tsuas yog kom pom cov hauv paus hauv paus tsis yog cov khoom siv qib lossis qhov ntsuas kub, tab sis cov pwm sib txawv ntawm cov ntawv luam tawm.
Vim li cas Sand Casting tseem yeej rau Precision Industrial Cheebtsam
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb khiav ob qho tib si xuab zeb thiab peev casting kab-tab sis khaws cov xuab zeb casting rau qhov chaw uas thermal mass, mechanical damping, los yog loj-scale geometry xav tau nws: piston twj tso kua mis lub tog raj kheej vaj tse mus txog 1,200 mm ntev, engineering tsheb winch center ncej chais 0 lub cev hnyav, 2 1 kg valve. Cov no tsis yog "qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob" Lawv nyob ze-net-puab castings tuav mus rau ± 0.3 hli ntawm qhov tseem ceeb datum nto, nrog nto tas li nruj li Ra 6.3 µm ntawm machined interfaces.
Tus yuam sij tsis hla qhov tseeb - nws yog embed nws ua ntej. Peb cov xuab zeb casting txheej txheem pib nrog CNC-machined qauv tooling (tsis yog ntoo los yog ua npuas ncauj), siv resin-bonded silica xuab zeb nrog tswj cov dej noo. <2.1% thiab permeability 110-130, thiab siv cov kev soj ntsuam ntawm lub sijhawm tiag tiag thaum lub sijhawm molding. Cov kauj ruam kawg nkaus ib leeg txiav cov tub ntxhais hloov qhov tsis xws luag los ntawm 74% piv rau phau ntawv ramming-cov ntaub ntawv txheeb xyuas hla 18 hydraulic manifold batches dhau Q3 2023.
Plaub qhov kev txiav txim siab uas ua los yog rhuav tshem koj qhov Casting
Feem ntau qhov ua tsis tiav rov qab mus rau ib qho ntawm plaub txoj kev xaiv ua ntej thawj cov xuab zeb kov lub khob:
- Cov qauv nyiaj pub dawb: Standard 1% shrink them nyiaj poob haujlwm rau cobalt-nickel alloys zoo li AMS 5387. Peb thov cov nyiaj sib txawv-0.92% axial, 0.85% radial-rau T800-raws li lub twj tso kua mis los tuav GD&T callouts ntawm bearing journals.
- Riser tsim logic: Tsis ntim raws li, tab sis solidification-lub sij hawm-match. Peb simulate txias nkhaus siv MAGMAsoft, tom qab ntawd tso cov ris tsho insulated nkaus xwb qhov twg lub sij hawm solidification hauv zos poob qis dua 87% ntawm qhov tuab tshaj plaws hauv paus.
- Pwm venting qhov chaw: Vents mus 12 mm los ntawm cope / core parting kab - tsis randomly - raws li zoo raws li kom khiav tawm gas flow paths mapped ntawm lub tshuab nqus tsev vacuum kuaj.
- Lub sijhawm sib tw: Tsis txhob "thaum txias txaus los tuav." Rau ductile hlau castings saum toj no 80 hli seem thickness, peb ncua shakeout kom txog thaum qhov kub thiab txias hits 520 ° C ± 15 ° C. Deviate los ntawm ntau tshaj 20 ° C, thiab residual stress spikes 3.2 × nyob rau hauv lub twj tso kua mis foundation mounting lugs.
Thaum Sand Casting Outperforms Peev Casting-Thiab Thaum Nws Tsis Ua
Qee tus engineers default rau peev casting rau "precision." Tab sis qhov ntawd yog ib qho cuab yeej. Peev casting excels qis dua 15 kg thiab nyob rau hauv 150 mm max dimension-tseem tawm tsam nrog cov lus sab hauv loj dua Ø25 mm los yog phab ntsa hloov thickness dua 45 mm tsis muaj kua muag kub. Tsis ntev los no peb rov ua dua ib qho kev txiav txim siab cobalt alloy nozzle: tib yam khoom AMS 5387, tib lub luam, ob txheej txheem. Kev nqis peev casting xa tawm 92% tawm los - tab sis yuav tsum tau 11 teev ntawm EDM ntxuav ib feem kom tshem tawm cov khoom seem ntawm cov 320 hli sab hauv. Xuab zeb casting? 98%.
Txawm li cas los xij-xuab zeb casting ua tsis tau sai thaum koj xav tau Ra ≤1.6 µm as-cam khwb cia, lossis nta me dua Ø3 hli nrog qhov tob-rau-inch> 4. Cov no mus ncaj nraim rau CNC machining los ntawm cov khoom bar. Peb tsis yuam cov txheej txheem kom haum. Peb cov ntawv tshaj tawm tau tshaj tawm cov kev tsis sib haum xeeb ua ntej, nrog rau cov kev xaiv los ntawm tag nrho cov nqi ntawm ib chav ua haujlwm - tsis yog ib kilogram lossis ib teev.
Dab tsi tiag-Lub Ntiaj Teb Kev Tswj Xyuas Zoo Zoo li
"ISO-certified foundry" txhais tau tias me ntsis yog tias kev tshuaj xyuas nres ntawm tensile tuav. Ntawm peb lub chaw Qingdao, txhua qhov kev tsim cov xuab zeb ua tiav plaub qhov yuav tsum tau kuaj xyuas:
- Kev txheeb xyuas cov xuab zeb batch: Sieve faib, cov ntsiab lus av nplaum, thiab poob-on-ignition nkag rau hauv ASTM C1107.
- Pre-pom pwm hardness pov thawj: Shore Scleroscope nyeem ≥72 ntawm tag nrho cov cope/core nto, kaw rau ib qhov chaw casting.
- Tom qab-shakeout ultrasonic scanning: 100% volumetric tshuaj xyuas rau subsurface shrink ntawm qhov tseem ceeb seem - tsis muaj sampling.
- Qhov kawg CMM validation: Tag nrho GD&T tsab ntawv ceeb toom tawm tsam thawj daim duab, suav nrog datum feature stability checks tom qab kev ntxhov siab-relief tshav kub kho.
Peb khaws tag nrho traceability: raw cov xuab zeb ntau, yaj rauv cav, pwm hardness maps, thiab CMM taw tes huab-txhua yam khi rau koj PO tooj. Tsis muaj kev zam. Qhov ntawd yog li cas peb lav lub siab lub cev ua tau raws li API 6D cov cai nyob thoob plaws peb daim ntawv cog lus hluav taws xob North American - tsis muaj ib qho kev ua tsis tiav hauv 22 lub hlis.
Npaj kom zoo rau koj qhov Casting Tom ntej?
Yog tias koj qhov hnyav 8-300 kg, ua haujlwm nyob rau hauv lub zog cyclic los yog abrasive hnav, thiab yuav tsum tau metallurgical sib xws ntawm cov khoom siv-xuab zeb casting tsis yog koj qhov kev xaiv rov qab. Nws yog koj qhov kev ua haujlwm ntau ntxiv. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsim cov castings uas muaj sia nyob - tsis yog dhau - kev xeem ntawv pov thawj. Peb pib nrog koj lub hom phiaj ua haujlwm, tsis yog koj daim duab. Tom qab ntawd peb sib piv cov txheej txheem, cov khoom siv, thiab kev tshuaj xyuas rau yam uas daim ntawv thov xav tau - tsis yog li cas hauv phau ntawv hais tias ua tau.
Mus ntsib https://www.tsingtaocnc.com thov kev tshuaj xyuas kev tsim khoom. Nqa koj GD&T, ib puag ncig kev ua haujlwm, thiab keeb kwm tsis ua haujlwm. Peb yuav qhia rau koj tias cov yam ntxwv twg yuav tsum tau cam khwb cia, uas yuav tsum tau machined, thiab qhov twg xuab zeb casting manufacturing muab ntsuas ROI-ua ntej koj txiav ib tug qauv.
