Thaum engineers qhia a poob ciab peev casting Hoobkas rau cov khoom hlau uas muaj kev ncaj ncees siab, lawv tsis yog tsuas yog yuav cov castings xwb-lawv tab tom ua kom muaj qhov rov ua tau zoo dua qub, kev tswj hwm microstructural, thiab kev ntseeg tau ua haujlwm nyob rau hauv cov kev pabcuam huab cua. Peb tau pom ntau txoj haujlwm qeeb - tsis yog los ntawm kev tsim teeb meem, tab sis los ntawm kev ua tsis tau zoo los ntawm kev muaj peev xwm. Lub vaj tsev nyob uas dhau CMM tshuaj xyuas ntawm chav tsev kub tuaj yeem hloov pauv tom qab kev kho cua sov yog tias lub chaw tsim khoom tsis muaj cov txheej txheem thermal validation. Lub cobalt alloy nozzle tuaj yeem ua tau raws li cov tshuaj tshwj xeeb ntawm daim ntawv tab sis ua tsis tiav hauv kev pabcuam yaig kuj yog tias cov qauv nplej tsis tau saib xyuas thoob plaws lub ncuav. Tias yog vim li cas precision tsis txhais los ntawm kev kam rau ib leeg-nws tau ua rau hauv kev ua haujlwm.
Vim li cas Poob Wax Investment Casting Demands Vertical Integration - Tsis yog Foundry xwb
Kev nqis peev casting zoo tshaj qhov uas cov xuab zeb tuaj yeem tsis tuaj yeem: cov phab ntsa nyias, cov txheej txheem sab hauv, nruj GD&T callouts, thiab cov npoo zoo (Ra ≤ 1.6 µm). Tab sis cov txiaj ntsig zoo no tawg yam tsis muaj kev sib txuas nruj ntawm cov qauv tsim, lub plhaub tsev, dewaxing, firing, pouring, thiab post-cast machining. Ntawm peb qhov chaw nyob hauv Qingdao, peb tsis outsource ib qho ntawm cov kauj ruam no. Peb tswj tag nrho cov saw-los ntawm silicone tooling rau cov qauv siv quav ciab rau lub tshuab nqus tsev-pab ceramic plhaub kom qhuav, los ntawm kev tswj-kub dewax ncu rau inert-gas pouring ntawm AMS 5387 cobalt alloy ntawm 1,480 ° C. Vim li cas qhov ntawd tseem ceeb? Vim tias cov wax residue ua rau lub plhaub tawg. Uneven plhaub drying caw porosity. Thermal shock thaum lub sij hawm dewaxing tsim microfractures pom tsis tau rau X-ray tab sis tuag nyob rau hauv cyclic siab. Peb tau ntsuas txog li 22% txo qis hauv thawj-dhau tawm los thaum lub plhaub kev ncaj ncees tsis raug siv raws li ASTM F2897.
Qhov twg Cov Khoom Txawj Ntse cais cov neeg muag khoom los ntawm cov neeg koom tes
Feem ntau cov foundries cam khwb cia hlau stainless los yog hlau ductile. Ob peb kov T800 cobalt-raws li alloys-los yog ua li ntawd yam tsis muaj kev txi machinability. Peb tau khiav ntau tshaj 1,400 qhov cua sov ntawm AMS 5387 txij li xyoo 2019, txhua qhov kev txheeb xyuas nrog OES spectroscopy thiab batch-traceable tshav kub kho cav. Cov neeg siv khoom feem ntau nug: "Koj puas tuaj yeem tuav ± 0.025 hli ntawm 320 hli piston twj tso kua mis lub tog raj kheej vaj tsev?" Yog—tab sis tsuas yog vim peb tshuab * tom qab * kev ntxhov siab thiab ua ntej kev laus kawg. Yog tias peb nrum nws, kub-kho nws, ces tos 72 teev ua ntej machining, residual stresses distort lub bore. Peb tsis hla cov kauj ruam ntawd. Peb kuj zam kev luv luv: tsis muaj "generic" cobalt alloy hloov pauv, tsis muaj cov khoom siv tshwj xeeb rau kev kho vuam, tsis muaj ntaub ntawv ua haujlwm thib ob. Txhua qhov cobalt alloy plug, txhua qhov tsis yog tus qauv twj tso kua mis, nqa tag nrho cov ntaub ntawv pov thawj, cov ntawv ceeb toom tensile, thiab hardness mapping hla cov cheeb tsam tseem ceeb.
Kev qhuab ntuas tiag tiag hauv ntiaj teb—tsis yog daim ntawv pov thawj xwb
ISO 9001 yog cov rooj tog zaum. Qhov tseem ceeb yog qhov kev txhais lus nruj npaum li cas rau koj feem. Peb cov txheej txheem tshuaj xyuas pib nrog cov ntaub ntawv pov thawj tuaj-tsis yog tsuas yog daim ntawv pov thawj zeb, tab sis kev kuaj ultrasonic rau qhov tsis sib xws. Thaum lub sij hawm casting, thermocouples saib pwm preheat thiab hlau ncuav kub hauv lub sijhawm. Tom qab shakeout, txhua qhov casting raug tshuaj ntsuam xyuas (ASTM E165) thiab radiography (ASTM E94) ua ntej machining ntxhib. Kev tshuaj xyuas zaum kawg suav nrog CMM scanning ntawm tag nrho GD&T nta, ntsuas qhov muag ntawm qhov chaw sib khi, thiab kev sim ua haujlwm-xws li kev kuaj xyuas hydrostatic siab ntawm 1.5 × ua haujlwm siab rau lub cev valve. Ib qho European hydraulic OEM txo qhov kev ua tsis tiav los ntawm 68% tom qab hloov mus rau peb lub tog raj kheej vaj tse - tsis yog vim kev ua siab ntev nruj, tab sis vim peb tau kos duab thiab tswj kev cuam tshuam vectors hla 12 lub voj voog thermal.
Xaiv txoj cai Poob Wax Investment Casting Factory txhais tau tias nug cov lus nug zoo
Tsis txhob nug "Koj puas muaj ntawv pov thawj ISO?" Nug: "Yuav ua li cas koj validate lub plhaub lub zog ua ntej dewaxing?" Tsis txhob nug "Dab tsi alloys koj nrum?" Nug: "Qhia kuv koj qhov kev kho cua sov peb zaug kawg rau AMS 5387-thiab cov txiaj ntsig tensile sib raug." Tsis txhob nug "Koj lub sijhawm ua haujlwm yog dab tsi?" Nug: "Yuav ua li cas koj tswj qhov seem ntawm qhov kev sib tw thiab qhov kawg ntawm qhov kawg ntawm 450 mm winch center ncej cov menyuam?" Cov lus teb qhia txog kev loj hlob ntawm kev ua haujlwm. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb cov lus nug nrog cov txheej txheem sau tseg, tsis yog cov lus cog tseg. Peb ua haujlwm rau North American oilfield twj cov tuam txhab uas xav tau ASME B16.34 ua raws li, German engineering tsheb cov neeg xa khoom xav tau EN 1559-3 traceability, thiab cov neeg tsim khoom tshwj xeeb hauv South Asia xav tau Ra ≤ 0.8 µm sealing nto-tag nrho los ntawm ib kab sib xyaw. Precision casting tsis yog hais txog kev tshem tawm kev hloov pauv. Nws yog hais txog kev ntsuas, kos duab, thiab tswj nws - txhua qhov cua sov, txhua qhov ntau, txhua ntu.
