Thaum engineers qhia a wax hlau casting Hoobkas rau cov khoom uas muaj kev ncaj ncees-tshwj xeeb tshaj yog cov uas raug rau siab heev, corrosion, los yog abrasive hnav-lawv tsis yog yuav ib feem xwb. Lawv ua kom ruaj ntseg ntawm qhov ntev, microstructural zoo ib yam, thiab kev ntseeg tau ua haujlwm thoob plaws ntau txhiab lub sijhawm ua haujlwm. Tias yog vim li cas precision peev casting tsis yog outsourced maj mam. Nws tau tso siab tsuas yog qhov kev qhuab qhia metallurgical ua tau raws li kev tswj hwm kev tswj hwm-thiab qhov twg txhua tus qauv siv quav ciab, lub plhaub ci ci, thiab kev kho cua sov tom qab pov tseg yog traceable, rov ua dua, thiab siv tau.
Vim li cas "Wax Hlau Casting" tseem yog tus qauv kub rau Lub Hom Phiaj-Critical Parts
Kev nqis peev casting-feem ntau hu ua "poob-wax casting"-tseem tsis sib haum rau cov geometries nyuaj hauv cobalt-nickel alloys, stainless hlau, thiab cov hlau muaj zog. Tsis zoo li cov xuab zeb casting, nws muab nto tiav zoo li Ra 1.6 μm thiab kam rau siab mus rau ± 0.05 hli ntawm cov yam ntxwv tseem ceeb. Tab sis raw muaj peev xwm txhais tau tias me ntsis yam tsis muaj txheej txheem tswv cuab. Peb tau pom ntau txoj haujlwm ua tsis tiav - tsis yog los ntawm kev tsim teeb meem, tab sis los ntawm cov khoom sib cais: ib tus neeg muag khoom pov tseg, lwm lub tshuab, ib feem peb ua kom sov. Txhua qhov kev sib tw ua rau muaj kev cuam tshuam tsis zoo hauv thermal expansion coefficient, residual stress distribution, los yog GD&T txhais.
Lub hwj chim tiag tiag tsis yog khoom siv-nws yog kev sib koom ua ke. Ib qhov tseeb wax hlau casting Hoobkas yuav tsum muaj lub voj voog tag nrho: siv quav ciab qauv cuab yeej, ceramic plhaub formulation, alloy melting thiab ncuav tswj, CNC machining ntawm ze-net duab, thiab zaum kawg kev soj ntsuam tsis muaj kev puas tsuaj. Yog tias tsis muaj kev tswj xyuas ntsug, txawm tias AMS 5387 cobalt alloy qhov chaw tuaj yeem raug kev sib cais sib cais lossis qhov sib txawv hauv cheeb tsam nyuaj-ua tsis pom kev kom txog thaum kev pabcuam.
Plaub lub peev xwm tsis sib tham tau koj yuav tsum txheeb xyuas
Ua ntej kos npe rau NDA lossis sib qhia koj lub twj tso kua mis hauv tsev, nug cov lus nug no-thiab thov cov pov thawj:
- Lawv puas cam thiab tshuab tib yam khoom? Yog tias tsis yog, thov kom tag nrho cov ntaub ntawv taug qab taug qab txuas mus rau cov ntawv pov thawj ntau ID rau cov ntawv teeb tsa thiab CMM cov ntaub ntawv.
- Lawv puas tuaj yeem siv tau microstructure rau ASTM E112 lossis E384? Grain loj, carbide dispersion, thiab delta ferrite cov ntsiab lus ncaj qha cuam tshuam lub neej qaug zog hauv hydraulic valve lub cev.
- Dab tsi yog lawv cov ntaub ntawv pov thawj cov khoom xa tuaj? Cov ntawv pov thawj zeb xeem ntawv ib leeg tsis txaus. Cov khw muaj npe nrov ua OES (optical emission spectroscopy) ntawm txhua tus nqi yaj-thiab khaws cov qauv rau 10+ xyoo.
- Lawv tuav T800-qib cobalt-raws li alloys li cas? Cov ntaub ntawv no ua haujlwm hnyav heev. Cov khw muaj kev vam meej siv cov qauv 5-axis mills nrog cov khoom siv hluav taws xob cryogenic-tsis yog cov txheej txheem dej nyab.
Peb tau sim tshaj 17 tus neeg muag khoom thov "cov kws tshaj lij cobalt". Tsuas yog peb dhau ntawm peb qhov kev ua haujlwm tau zoo: 200-teev lub zog cycling ntawm 450 bar, ua raws li kev tshuaj xyuas ultrasonic rau subsurface cracking. Ob tug ua tsis tau tejyam ntawm thermal distortion thaum kawg machining. Ib qho dhau mus - tab sis tsis tuaj yeem rov ua cov txiaj ntsig hla peb pawg sib law liag vim lub plhaub tsis sib haum kom qhuav cov av noo tswj.
Qhov twg Precision Casting ntsib tiag-lub ntiaj teb xav tau
Saib dhau catalog specs. Kev ua haujlwm tiag tiag tshwm sim hauv qab load. Piv txwv li: piston twj tso kua mis lub tog raj kheej vaj tse yuav tsum bore roundness ≤0.015 hli * tom qab * kev ntxhov siab-relieving tshav kub kev kho mob - tsis yog li-casting. Engineering tsheb winch center ncej rollers xav tau qhov tawv tawv ntawm 58-62 HRC * nrog * qhov tsawg kawg nkaus qhov tob ntawm 1.2 hli - ua tiav los ntawm carburizing * tom qab * machining, tsis ua ntej. Thiab AMS 5387 nozzles? Lawv lub caj pas geometry kam rau ua yog ± 0.025 hli - tsis yog vim cov duab kos tau hais li ntawd, tab sis vim tias ntws coefficient sib txawv> ± 1.8% ua rau cavitation yaig nyob rau hauv qis dua 800 teev ua haujlwm.
Qhov no yog vim li cas QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. txhim kho nws cov kev ua haujlwm nyob ib puag ncig cov txiaj ntsig kev ua haujlwm - tsis yog kev sib koom tes ntawm pawg haujlwm. Txhua cobalt alloy plug pib nrog ntawv pov thawj T800 billet, undergoes nqus induction melting nrog argon shrouding, solidifies nyob rau hauv tswj-rate pwm, ces tsiv-tsis muaj ib puag ncig raug-mus rau ib tug huab cua-stabilized CNC cell. Tsis muaj rework loops. Tsis muaj dimensional drift. Tsuas yog cov ntaub ntawv rov ua dua.
Xaiv koj tus khub tsis yog hais txog Geography-Nws yog hais txog kev tswj hwm
A wax hlau casting Hoobkas hauv Qingdao muab qhov zoo ib yam rau ib qho hauv Ohio-yog tias nws qhov kev ua tau zoo tswj hwm tib yam nruj. ISO 9001 daim ntawv pov thawj yog cov rooj tog zaum. Dab tsi tseem ceeb yog lawv siv li cas: Cov chaw kuaj xyuas puas ua raws li koj qhov FMEA? Puas yog CMM cov kev pabcuam sau rau hauv Calypso lossis PC-DMIS-thiab tau lees paub tiv thaiv cov khoom ntiag tug tuaj yeem taug qab rau NIST? Lawv puas tuaj yeem xa cov ntaub ntawv PPAP Qib 3 hauv tsib hnub ua haujlwm ntawm thawj tsab ntawv pom zoo?
Cov neeg siv khoom thoob ntiaj teb - los ntawm German twj tso kua mis OEMs rau North American oilfield cov chaw muab kev pabcuam - xaiv cov neeg koom tes uas kho engineering tshuaj xyuas raws li kev tsim kho. Tsis yog "ntawm no yog koj qhov kev tsocai," tab sis "koj GD&T hu rau MMC ntawm cov ntaub ntawv no; ntawm no yog qhov peb yuav tuav nws thaum tsim kho-thiab ntawm no yog qhov pheej hmoo yog tias peb tsis ua." Qhov theem ntawm kev pom tseeb txiav lub sij hawm-rau-tsim los ntawm 30% nyob rau nruab nrab. Nws kuj tseem tiv thaiv tus nqi rov tsim dua tshiab tom qab thawj tsab xov xwm tsis ua tiav.
Saib rau pem hauv ntej, tom ntej pem hauv ntej tsis yog lub tshuab loj dua lossis nrawm dua. Nws yog cov txheej txheem hybrid: casting ze-net duab nrog kev sib xyaw ua ke cua txias, tom qab ntawd tsuas yog ua tiav qhov sib khi nrog electrochemical machining. Nws yog digital ntxaib validation ntawm thermal distortion qauv ua ntej pouring thawj lub plhaub. Nws tau lees paub txhua T800 tivthaiv rau ASME BPVC Tshooj VIII, Div. 2-tsis yog rau kev tiv thaiv siab xwb, tab sis rau kev ua kom qaug zog ntawm lub neej.
Yog tias koj daim ntawv thov xav tau xoom paj rau qhov ua yuam kev - thiab koj cov khoom ua haujlwm qhov tsis ua haujlwm tsis yog qhov kev xaiv - ces koj wax hlau casting Hoobkas yuav tsum ntsuas nyob rau hauv cov txiaj ntsig, tsis yog cov zis. Tsis muaj pes tsawg tons lawv pov ib lub hlis. Muaj pes tsawg lab lub zog cycles lawv qhov chaw nyob. Muaj pes tsawg daim teb rov qab lawv tau nkag hauv tsib xyoos. Muaj pes tsawg tus neeg tau txais kev cog lus txuas ntxiv - tsis yog ib zaug, tab sis peb zaug.
