Thaum cov engineers xav tau micro peev casting Hoobkas muaj peev xwm rau qhov chaw hauv qab 50 hli nrog ± 0.02 hli kam rau ua thiab nto tiav nyob rau hauv Ra 1.6 µm, feem ntau cov neeg muag khoom ntaus phab ntsa. Peb tau pom nws ntau zaus: cov qauv ncua sij hawm los ntawm rau lub lis piam, castings tsis lees paub rau micro-porosity hauv txoj hauv kev tseem ceeb, lossis cobalt alloy nozzles ua tsis tau qhov ntsuas siab tom qab kev kho cua sov. Qhov ntawd tsis yog qhov teeb meem ntawm cov ntaub ntawv - nws yog qhov teeb meem ntawm kev sib koom ua ke.
Micro Investment Casting xav tau ntau dua li cov pwm me
Muaj tseeb micro peev casting tsis yog "me me" peev casting. Nws yuav tsum muaj kev tswj xyuas nruj dua ntawm cov qauv siv quav ciab, lub plhaub ceramic permeability, hlau superheat, thiab tus nqi solidification-tshwj xeeb tshaj yog thaum casting nyias-walled (0.8-2.5 hli) cov khoom los ntawm AMS 5387 cobalt alloy lossis T800-based superalloys. Cov qauv tsim feem ntau hla ua ntej tsim cov qauv thermal los yog siv cov zaub mov txawv ntawm lub plhaub. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua txoj haujlwm micro-casting pib nrog kev ua haujlwm ruaj khov simulation-tsis yog lub thawv ntawv, tab sis los kwv yees qhov chaw nyob qhov twg muaj kev ntxhov siab nyob hauv 12-mm-inch twj tso kua mis ntsaws nrog cov cua txias sab hauv.
Peb ib zaug tau khiav peb lub plhaub iterations rau lub rooj zaum hydraulic ua ntej xauv lub slurry viscosity, poob lub sijhawm nyob, thiab dewaxing ramp profile. Qhov txawv? Kev txo qis ntawm 40% ntawm microporosity ntawm lub qhov rooj sib tshuam - txheeb xyuas los ntawm X-ray CT scan, tsis yog dye penetrant. Qhov ntawd yog li cas koj ua tiav kev ua haujlwm ncaj ncees hauv qhov chaw ua haujlwm ntawm 350 bar thiab 180 ° C.
Vim li cas Vertical Integration Beats Outsourced Casting + Machining
Qee tus neeg tsim khoom pov tseg qhov khoob, tom qab ntawd xa mus rau lub khw CNC. Tab sis micro-features zoo li 0.3-mm radial grooves ntawm lub piston twj tso kua mis lub tog raj kheej vaj tse xav tau machining * ua ntej * zaum kawg kev kho cua sov - txwv tsis pub, distortion ruins GD&T ua raws. Lwm lub tshuab ua ntej, tom qab ntawd pov ib ncig ntawm cov khoom siv-qhia cov voids interfacial.
QINGDAO QIANGSENYUAN ua haujlwm ob leeg hauv ib qho chaw ua raws ISO. Piv txwv li: ib tug cobalt-nickel alloy winch center ncej cov menyuam pib raws li ib tug peev-cam khwb cia nyob ze-net zoo, undergoes cov tshuaj annealing, tau precision-tig rau 5-axis DMG Mori nrog in-process laser probing, ces tau txais hard-chrome plating nrog tswj thickness (25-35 µm) xyuas los ntawm cross-section S. Tsis muaj handoffs. Tsis muaj batch mismatches. Tsis ploj traceability.
- CNC machining chaw calibrated txhua hnub rau ISO 230-2 tus qauv
- Plhaub pwm ziab hauv cov av noo-tswj chamber (RH <35%) ua ntej tua
- Tag nrho cov cobalt alloys tau los nrog tag nrho cov ntawv soj ntsuam zeb (MTRs), suav nrog cov nplej loj thiab kev txheeb xyuas carbide
- Txhua feem mapped nrog CMM cov ntaub ntawv khi rau nws raw cov ntaub ntawv kub tooj
Kev txwv hauv ntiaj teb tiag—thiab Yuav Ua Li Cas Ua Haujlwm Hauv Lawv
Micro peev casting tsis yog khawv koob. Phab ntsa thickness hauv qab 0.6 hli txaus ntshai ua tsis tiav pwm filling. Nta me dua 0.2 hli tsis tshua muaj sia nyob tshem tawm lub plhaub tsis muaj yaig. Thiab yog - AMS 5387 shrinks 1.92% ntawm qhov nruab nrab, tab sis cov shrinkage hauv zos tuaj yeem sib txawv ± 0.15% nyob ntawm qhov nyob ib sab. Qee cov neeg siv khoom xav tias "micro" txhais tau tias "tsis muaj ntawv sau". Tsis yog. Txawm tias 0.5 ° cov cua ntsawj ntshab txuag cov cuab yeej siv lub neej thiab tiv thaiv lub plhaub tawg thaum dewaxing.
Tias yog vim li cas peb lub tuam txhab tshuaj xyuas cov chij tsim cov cuab yeej thaum ntxov: cov kaum sab hauv ntse ua rau lub kua muag kub, tsis muaj kev txhawb nqa nyias tav tsoo thaum kub hnyiab, lossis tsis sib haum xeeb thermal expansion ntawm cobalt alloy thiab stainless hlau inserts. Peb tsis hais "yog" rau txhua daim duab - peb nug "Qhov no pom dab tsi? Qhov kev ua tsis tiav yog dab tsi?" Tom qab ntawd peb kho cov rooj vag, hloov cov risers, lossis qhia txog kev sib xyaw cast-and-brazed mus kom ze.
Ib lub twj tso kua mis European OEM hloov kho lawv lub taub hau geometry tom qab peb cov lus qhia txog kev tsim khoom-txiav tawm los ntawm 68% mus rau 94%, thiab tshem tawm ob qhov kev sib tsoo tom qab. Tus nqi ib feem poob 22%. Lub sij hawm ua ntej shrink ntawm 14 mus rau 9 lub lis piam.
Xaiv lub Micro Investment Casting Factory txhais tau tias xaiv tus txheej txheem tus khub
Ib qho kev txhim khu kev lag luam micro peev casting Hoobkas muab ntau tshaj qhov sib npaug. Nws muab metallurgical sib xws thoob plaws 500-thooj batch. Nws tuav Ra 0.8 µm ntawm cov bores sab hauv yam tsis muaj qhov thib ob honing. Nws taug qab txhua gram ntawm T800 alloy rov qab rau nws cov cav yaj-tsis yog batch ID. Nws siv tau cov txheej txheem tshuaj xyuas tawm tsam ASME Y14.5 thiab EN ISO 1101, tsis yog cov neeg siv khoom PO sau ntawv xwb.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm li no vim tias muaj cov tshuab hydraulic siab, cov cuab yeej siv roj av sab nrauv, thiab cov tshuab tsim tsheb winches zam tsis muaj kev cuam tshuam. Thaum koj cov khoom lag luam tswj cov dej ntws hauv dej hiav txwv, "kaw txaus" tsis muaj nyob.
Nrhiav cov txheej txheem tswj cov ntaub ntawv-tsis yog phau ntawv qhia. Nug cov qauv CMM cov ntaub ntawv nrog GD&T callouts. Thov cov ntaub ntawv pov thawj ntawm kev kho cua sov hauv tsev nrog rau cov ntawv pov thawj ntawm lub tshuab hluav taws xob. Xyuas seb lawv muaj lawv lub plhaub lab lossis cov khoom siv slurry npaj. Thiab ib txwm sim lawv cov lus teb ntawm tus qauv me me ua ntej ua haujlwm rau ntim.
Lub neej yav tom ntej yog rau cov chaw tsim khoom uas kho micro peev casting raws li kev qhuab qhia physics-tsav-tsis yog kev tawm dag zog. Qhov ntawd txhais tau tias tob R & D rau hauv cov tshuab qis qis qis, AI-pab lub plhaub tsis xws luag kwv yees, thiab cov txheej txheem hybrid merging peev casting nrog xaiv laser melting rau ultra-thin nta. Yog tias koj qhov project tom ntej no xav tau kev tsim khoom me me qhov twg microstructure, geometry, thiab kev ua haujlwm tsis sib tham - pib nrog cov txheej txheem nruj, tsis yog tus nqi xwb.
