Thaum cov engineers qhia txog ib feem uas yuav tsum tuav ± 0.02 hli tolerances, ciaj sia 400 ° C thermal cycling, thiab tiv taus yaig los ntawm abrasive slurry - tsis muaj chaw rau casting kwv yees. Qhov ntawd yog qhov twg peev casting foundry Hoobkas nrog pov thawj metallurgical kev qhuab qhia ua rau qhov sib txawv ntawm kev ua haujlwm tsis ua haujlwm thiab 15 xyoo kev pabcuam lub neej. Peb tau pom nws ua ntej: lub hydraulic twj tso kua mis vaj tse tawg ntawm 8,000 psi thaum lub sij hawm siv tau - tsis yog vim yog tsim, tab sis vim hais tias cov as-cam microstructure muaj undetected shrink porosity nyob ze ntawm lub rooj zaum valve. Kev kho tsis tau retooling. Nws tau hloov mus rau tus khub uas tswj cov hlau yaj chemistry, lub plhaub ziab kom qhuav, thiab dewaxing ramp tus nqi - tsis yog "casting parts," tab sis engineering castings.
Precision pib ua ntej thawj ncuav
Qhov tseeb peev casting precision tsis ua tiav hauv qhov cub. Nws pib nrog cov ntaub ntawv traceability thiab txheej txheem repeatability. Ntawm peb qhov chaw ua haujlwm ISO-raws li hauv Qingdao, txhua qhov cobalt-nickel alloy batch nqa tag nrho cov ntaub ntawv pov thawj thaum tshav kub kub-los ntawm raw ingot tsom xam (AMS 5387, ASTM F75) mus rau qhov kawg kev daws teeb meem-annealed tensile tau. Peb tsis lees txais "tus qauv" chemistry. Peb txheeb xyuas chromium, molybdenum, thiab cov ntsiab lus carbon ua ntej nchuav-thiab sau txhua qhov ntsuas: lub plhaub kub, lub sijhawm dewaxing nyob, preheat so lub sijhawm, thiab lub tshuab nqus tsev-pas dej tshaj tawm. Vim li cas? Vim tias qhov sib txawv ntawm 2 ° C nyob rau hauv pwm preheat hloov pauv tus nqi txaus kom hloov pauv cov ciam teb carbide faib hauv T800-qib superalloys. Qhov ntawd cuam tshuam ncaj qha rau qaug zog tiv thaiv hauv piston twj tso kua mis lub tog raj kheej nyob hauv qab kev thauj khoom cyclic.
Peb tau lees paub qhov no hla 127 kev tsim khoom ntawm AMS 5387 cobalt alloy 6 twj tso kua mis. Cov khoom cam khwb cia nyob rau hauv kev tswj tsis tau pom 31% siab dua lub voj voog qaug zog lub neej piv rau zoo tib yam geometry cam khwb cia siv generic khw-pem teb chaw. Qhov txawv tsis yog machining - nws yog qhov casting nws tus kheej.
Vertical Integration Tsis yog Buzzword - Nws yog Kev Pov Hwm Dimensional
Qee tus neeg muag khoom outsource tiav. Lwm tus kho cov casting thiab CNC raws li cov tuam tsev sib cais. Peb ua ke lawv. Peb lub tuam txhab peev casting foundry ua haujlwm txhua yam: ceramic plhaub fabrication, precision casting, kev ntxhov siab-relieving tshav kub kev kho mob, multi-axis CNC machining (xws li 5-axis contouring ntawm sab hauv ntws paths), thiab kev kho deg zoo li HVOF tungsten carbide txheej. Qhov no tshem tawm cov kev sib tshuam ntawm qhov sib txawv-qhov uas hloov GD&T-hais txog 0.015 hli txoj hauj lwm kam rau ua 0.032 hli pawg-up tom qab peb handoffs.
- Siab li qub machined ncaj qha los ntawm cam khwb cia blanks-tsis muaj lwm yam fixturing yuav tsum tau
- Twj lub hauv paus nrog kev sib txuas mounting flanges thiab cov chaw nres nkoj dej, txhua tus tuav rau ASME B16.34 Chav Kawm 600 kam rau ua
- Engineering tsheb winch center ncej chais nrog hardened hnav nto thiab tsis-destructively txheeb xyuas subsurface kev ncaj ncees
Thaum ib tug European OEM xav tau kev hloov cobalt alloy nozzles rau high-pressure descaling systems, lawv ua ntej xa khoom yuav tsum tau 100% re-machining kom tau raws li bore concentricity specs. Peb tau xa thawj qhov kev ua haujlwm dhau los-vim tias peb qhov kev pabcuam CNC nyeem ncaj qha los ntawm cov ntaub ntawv pov thawj CT scan, tsis yog qauv CAD theoretical.
Kev Tswj Xyuas Zoo Uas Ua, Tsis yog Cov Ntaub Ntawv
"Kev tshuaj xyuas" txhais tau tias tsis muaj dab tsi yog tias nws tshwm sim tsuas yog thaum kawg. Peb cov txheej txheem zoo embeds pov thawj ntawm plaub qhov chaw tsis sib tham: cov ntaub ntawv pov thawj tuaj, kev ntsuas CMM tom qab kev ua haujlwm ntxhib, kho qhov muag profileometry ntawm qhov tseem ceeb sealing nto, thiab kev sim ua haujlwm zaum kawg - suav nrog kev kuaj xyuas qhov siab ntawm 1.5 × kev ua haujlwm siab. Txhua feem tau txais daim npav ID tshwj xeeb txuas rau nws cov ntaub ntawv digital tag nrho: spectral tsom xam ntawm cov yaj, thermal keeb kwm nkhaus, kev sib koom ua ke daim ntawv qhia txog kev ntsuas, thiab daim ntawv qhia qhov chaw roughness.
Peb tau muaj cov neeg siv khoom nug: "Koj puas tuaj yeem lav xoom porosity hauv thaj tsam valve?" Cov lus teb yog tsis yog - peb lav kev kuaj pom. Yog tias peb lub tshuab kuaj xyuas ultrasonic txheeb xyuas qhov ntsuas ntau tshaj ASTM E1815 Theem 2, peb khawb ib feem. Tsis muaj kev zam. Qhov kev qhuab qhia ntawd tau khaws peb cov PPM qhov tsis xws luag qis dua 187 rau lub hom phiaj tseem ceeb ntawm cov khoom siv hydraulic hauv 37 lub hlis dhau los.
Kev xa tawm tiag tiag-Lub Sijhawm Ua Haujlwm tsis yog raws li tau cog lus tseg
Lub sij hawm ua cov lus cog tseg txhais tau tias me ntsis thaum tus qauv txiav txim rau 11 hnub tos ntawm cov ntaub ntawv pov thawj. Peb npaj tau ntawv pov thawj AMS 5387, F75, thiab stainless hlau 17-4PH nyob rau hauv ntau lub tshav kub-nrog tag nrho cov zeb xeem cov ntaub ntawv nyob rau hauv cov ntaub ntawv. Rau cov phiaj xwm ceev, peb tuaj yeem pib tsim lub plhaub tsis pub dhau 48 teev ntawm kev pom zoo kos duab. Peb cov kev ua haujlwm lean taug qab WIP los ntawm Kanban cov cim - tsis yog cov ntawv nthuav qhia - thiab peb qhov nruab nrab ntawm lub sijhawm xa khoom rau nruab nrab ntim xaj (50-500 pcs) sawv ntawm 98.4%, txheeb xyuas los ntawm cov neeg thib peb kev kuaj xyuas thoob plaws North America thiab EU xa khoom.
Ib lub chaw tsim khoom lag luam Esxias sab hnub tuaj tau txo tag nrho cov nqi tsaws los ntawm 22% tom qab hloov mus rau peb - tsis yog vim tias peb cov nqi tsev poob qis, tab sis vim tias lawv tshem tawm peb qhov kev tshuaj ntsuam xyuas, txiav cov seem ntawm 14% mus rau 0.9%, thiab tau txais cov lus pom zoo rau kev tsim khoom ua ntej kev cog lus.
Ib peev casting foundry Hoobkas khwv tau kev ntseeg tsis yog nrog cov ntawv qhia, tab sis nrog cov txheej txheem rov ua dua, cov ntaub ntawv keeb kwm thermal, thiab qhov ruaj khov ntawm qhov ntev ntawm 10,000 cycles. Precision hlau qhov chaw tsis zam qhov tsis meej. Tsis yog peb ua. Yog tias koj cov khoom txuas ntxiv xav tau ntau tshaj qhov kev zam txim - yog tias nws yuav tsum ua qhov tsis ua haujlwm tsis yog qhov kev xaiv - pib nrog cov txheej txheem casting, tsis yog daim ntawv xaj khoom.
