Thaum engineers qhia high precision magnesium alloy tuag casting Hoobkas, lawv tsis yog thov rau tus neeg muag khoom xwb - lawv tab tom xav kom muaj kev ruaj ntseg nyob rau hauv thermal cycling, microstructural uniformity nyob rau hauv nyias-walled seem, thiab tsis muaj kev cuam tshuam ntawm tensile lub zog ntawm siab kub kev pab cuam. Magnesium alloys zoo li AZ91D, AM60B, thiab WE43 muab qhov sib piv tsis sib haum xeeb-rau-qhov hnyav-tab sis tsuas yog tias cov txheej txheem tuag casting tswj hydrogen porosity, txo qhov tuag soldering, thiab xauv hauv ± 0.05 hli tolerances ntawm cov yam ntxwv me me li 0.8 hli phab ntsa thickness. Qhov kev tswj hwm qib ntawd tsis tshwm sim hauv cov chaw tsim khoom lag luam.
Peb tau nrum ntau dua 12,000 WE43 magnesium vaj tse rau aerospace hydraulic actuators - thiab txhua pawg tau dhau 100% X-ray tshuaj xyuas yam tsis muaj qhov qis qis. Vim li cas? Vim tias qhov tseeb magnesium tuag casting tsis yog hais txog lub tshuab loj dua lossis lub sijhawm voj voog nrawm dua. Nws yog hais txog kev tswj qhov kub thiab txias hauv ± 3 ° C, tswj qhov chaw tuag hauv qab Ra 0.4 μm, thiab siv lub tshuab nqus tsev pab txhawm rau txhawm rau oxide zaj duab xis entrapment. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho magnesium tsis yog "lub teeb txhuas", tab sis raws li ib tug reactive, oxygen tshaib plab hlau uas xav tau kev mob siab rau, inert-gas shielding, thiab real-time kab noj hniav siab xyuas.
Feem ntau cov magnesium tuag casting tsis ua tiav rov qab mus rau peb qhov kev zam tsis tau: kev ua kom tsis zoo ntawm cov nplej thaum lub sij hawm khov kho, tsis muaj kev tswj xyuas theem intermetallic (tshwj xeeb tshaj yog Mg17Al12), thiab post-casting distortion los ntawm residual stress so. Peb kaw cov qhov khoob no los ntawm kev sib koom ua ke kev simulation nrog qhov tseeb hauv-tuag thermocouple daim ntawv qhia-tom qab ntawd siv tau txhua qhov pwm geometry tiv thaiv ASTM B94-22 tensile bars thiab ISO 11992-2 leak-rate testing. Peb cov xuab zeb-casting magnesium prototypes ua tiav Cpk ≥ 1.67 ntawm qhov tseem ceeb GD&T callouts; ntau lawm khiav tuav ± 0.03 hli ntawm coaxiality ntawm bearing bores thiab mounting flanges - tsis muaj lwm yam machining.
Vertical integration ua qhov txawv. Thaum muaj ntau lub npe hu ua "precision" factories outsource tshav kub kho los yog CNC xov, peb tswj tag nrho cov saw: magnesium alloy melting nyob rau hauv graphite crucibles nyob rau hauv SF6/CO2 npog roj, siab-nqus tuag casting ntawm 720-740 ° C yaj temp, T6 tshuaj annealing nrog tswj tus nqi, thiab zaum kawg CMM pov thawj siv Zeiss CONTURA G2 nrog tactile scanning. Qhov no tshem tawm qhov yuam kev sib cuam tshuam - tsis muaj cov ntaub ntawv tsis raug ntawm cov chaw tsim khoom thiab lub khw muag khoom, tsis muaj keeb kwm zais thermal cuam tshuam rau machinability. Thaum lub twj tso kua mis European OEM xav tau magnesium lub tog raj kheej vaj tse nrog 0.1 hli flatness ntawm 220 mm lub ntsej muag thiab 300 MPa yield zog, peb tau xa cov khoom thawj zaug hauv 18 hnub - tsis yog vim peb maj, tab sis vim tias peb daim ntawv qhia txheej txheem tsis muaj kev xa tawm qeeb.
Kev ua haujlwm tiag tiag hauv ntiaj teb tseem ceeb tshaj li cov ntawv spec. Ib tus neeg siv khoom tau tshaj tawm 40% lub neej ua haujlwm ntev dua ntawm magnesium winch center ncej chais rau cov khoom sib npaug ntawm txhuas-tom qab 12,000 cycles hauv qab 85 kN radial load thiab ntsev-txhaj tshuaj. Vim li cas? Peb AMS 5387-tshaj cobalt-nickel inserts bonded rau hauv magnesium vaj tse tuav hardness saum 42 HRC thaum lub hauv paus alloy absorbed vibration zog. Qhov kev tsim hybrid no tsuas yog ua haujlwm thaum pawg casting thiab machining pab pawg sib koom tib lub rooj sib tham engineering-thiab thaum cov ntaub ntawv traceability txuas txhua feem ntawm nws qhov qub ingot ntau, lub cav rauv, thiab daim ntawv qhia txog tensile. Peb tsis tsuas yog ua tau raws li ISO 9001: 2015-peb embed AS9100-style kev pheej hmoo tshuaj xyuas rau hauv txhua qhov tshiab magnesium project kickoff.
Yog koj xav tau ib high precision magnesium alloy tuag casting Hoobkas uas kho magnesium raws li cov khoom siv engineering - tsis yog ib qho kev sib hloov - koj xav tau cov txheej txheem kev qhuab qhia, kev lav phib xaub ntawm metallurgical, thiab xoom kam rau kev kwv yees. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. xa cov kev nruj no hla hydraulic manifolds, twj tso kua mis foundations, thiab lub hom phiaj tseem ceeb ntawm lub tsheb Cheebtsam. Precision pib qhov twg cov yaj ua tau raws li qhov tuag-thiab nyob twj ywm rau hauv kom txog rau thaum kev soj ntsuam zaum kawg.
