Thaum cov kws tshaj lij qhia cov hlau tsis huv rau cov neeg ua haujlwm siab, lub luag haujlwm tseem ceeb - xav tias lub siab li qub hauv cov tshuab hydraulic lossis piston twj tso kua mis lub tog raj kheej - lawv xav tau ntau dua li kev tiv thaiv corrosion. Lawv xav tau kev ruaj ntseg nyob rau hauv thermal cycling, microstructural kev ncaj ncees tom qab sintering, thiab nto tiav uas muaj sia nyob abrasive flow media. Qhov ntawd yog qhov uas muaj kev mob siab rau hlau txhaj molding stainless hlau Hoobkas dhau los ua tsis yog-kev sib tham-tsis yog tus xa khoom, tab sis ua tus khub txheej txheem.
Yog vim li cas MIM Stainless Hlau xav tau ntsug kev koom ua ke - Tsis yog khoom siv xwb
Peb tau pom ntau qhov haujlwm nyob rau ntawm qhov qauv qauv vim tias MIM lub khw tau tuav cov khoom noj khoom haus sib xyaw thiab kev sib tham, tab sis cov khoom siv hluav taws xob tawm mus rau cov neeg siv hluav taws xob dav dav. Cov qib stainless hlau zoo li 17-4 PH lossis 316L coj tus cwj pwm tsis zoo yam tsis muaj kev tswj xyuas nruj ntawm cov pa oxygen ib feem, tus nqi nce, thiab tuav lub sijhawm thaum sintering. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tag nrho MIM workflow-los ntawm feedstock formulation nrog ntawv pov thawj stainless hlau hmoov (ASTM A985-raws li), los ntawm hnyav thiab thermal debinding, mus nqus-sintering nyob rau hauv ISO 9001-certified furnaces-yog . Tsis muaj handoffs. Tsis muaj batch-rau-batch variability nyob rau hauv grain loj hlob. Tsis xav tsis thoob thaum GD&T callouts thov ± 0.02 hli ntawm nyias-walled nta tsawg dua 1.2 hli tuab.
Qhov kev koom ua ke no tseem ceeb tshaj plaws thaum geometry ua tau raws li kev ua haujlwm. Lub winch center ncej cov menyuam rau engineering tsheb xav tau hardness ≥38 HRC * thiab * ib tug nto roughness ntawm Ra ≤0.8 µm - yuav tsum tau yuam kev lag luam tawm ntawm sintering ceev thiab post-MIM machining. Peb qhov chaw txuas hniav sib txawv: peb sinter ze-net-zoo, tom qab ntawd siv ntau-axis CNC tiav nrog kev kho cua sov - tsis muaj kev xa khoom sab nraud, tsis muaj qhov rov kho qhov yuam kev, tsis muaj kev poob ntawm datum txuas ntxiv.
Qhov twg Standard MIM Fails—thiab Yuav Ua Li Cas Cov Khoom Siv Tshwj Xeeb Kho Nws
Qee tus yuav sib cav hais tias ib tus kws kho mob MIM tuaj yeem ua cov hlau tsis muaj hlau yog tias lawv ua raws ASTM F2885. Tab sis hom kev ua tsis tiav tiag tiag hauv ntiaj teb qhia ib zaj dab neeg sib txawv. Peb tau taug qab rov qab tawg hauv 316L lub rooj zaum rov qab mus rau qhov seem ntawm cov binder cov pa roj carbon monoxide nyob rau ntawm cov ciam teb ntawm cov qoob loo - qhov tsis zoo uas pom tsis pom kev kho qhov muag tab sis muaj kev puas tsuaj loj nyob rau hauv lub zog siab. Kev kho tsis tau sai dua debinding; nws tau hloov los ntawm paraffin-raws li mus rau polyacetal-raws li binders * thiab * ntxiv ib qho chaw tswj hwm pre-sinter soak kauj ruam. Qhov kev hloov kho ntawd los ntawm 12 xyoo ntawm kev khiav AMS 5387 cobalt alloy nozzles-cov khoom siv nrog cov thermal expansion rhiab heev tab sis raug nqi ntau dua rau cov khoom seem.
Qhov kev paub ntawd hloov mus ncaj qha rau stainless hlau. Peb cov kws tshuaj metallurgists tsis kho 17-4 PH li "tsuas yog lwm qib." Lawv paub nws cov lus teb kev laus hloov yog sintering kub drifts ± 5 ° C. Lawv txheeb xyuas txhua cov hmoov nplej uas tuaj nrog OES tsom xam - tsis yog rau Fe / Cr / Ni, tab sis rau cov pa oxygen thiab nitrogen uas tswj cov pore morphology. Thiab lawv sau txhua qhov ntsuas: cov dej lwg taw tes hauv lub sintering chamber, siv ceev hauv qhov cub debinding, txawm tias ambient humidity thaum lub sij hawm ntsuab. Vim hais tias nyob rau hauv lub siab-siab twj tso kua mis sib dhos, ib tug 0.3% ceev variation tsis theoretical-nws yog ntxov ntxov qaug zog tsis ua hauj lwm ntawm 12,000 psi.
Los ntawm Kev Kos rau Kev Xa Khoom: Dab tsi "High-Precision" Tiag tiag txhais tau tias hauv kev xyaum
"High-precision" tau siv tsis tu ncua. Qhov tseeb tseeb txhais tau tias rov ua dua hla 500+ qhov chaw, tsis yog ib qho CMM scan xwb. Nws txhais tau tias tuav txoj hauj lwm tseeb ntawm Ø3.2 hli qhov nyob ntawm 42 hli sib nrug li ntawm 0.015 hli — * tom qab * sintering shrinkage, * tom qab * kev ntxhov siab nyem, * tom qab * passivation. Nov yog qhov peb xa nws:
- Incoming tswj: Raw stainless hlau hmoov kuaj rau particle loj faib (D50 ≤ 8.5 µm), pom meej ntom, thiab txaus tus nqi ib ASTM B212
- In-process verification: Ntsuab qhov hnyav nkag rau ib kab noj hniav; sintered ntom ntsuas los ntawm Archimedes txoj kev ntawm thawj-tawm thiab txhua txhua 50th feem
- Qhov kawg validation: 100% CMM tshuaj xyuas ntawm cov ntaub ntawv tseem ceeb; xaiv SEM/EDS ntawm cov pob txha tawg rau kev tsom xam pore
- Traceability: Txhua qhov ntau yog QR-coded daim ntawv pov thawj txuas cov hmoov nplej ntau, sintering khiav ID, tus neeg teb xov tooj cav, thiab daim ntawv ntsuam xyuas zaum kawg
Qhov no tsis yog overkill - nws yog lub hauv paus rau cov neeg siv khoom hauv cov roj & roj uas xav tau ASME B31.4 ua raws li EU PED 2014/68 / EU cov ntaub ntawv. Peb tsis "ntxiv cov ntawv pov thawj tom qab." Peb tsim qhov system ua ntej, tom qab ntawd tshawb xyuas tawm tsam nws.
Xaiv Koj Cov Hlau Txhaj Tshuaj Moulding Stainless Steel Factory - Saib yav dhau los daim ntawv qhia
Yog tias koj qhov project tom ntej no suav nrog stainless hlau MIM qhov chaw rau hydraulic manifolds, twj tso kua mis, lossis kev cai cobalt-stainless hybrids, nug peb cov lus nug ua ntej kos npe rau PO:
- Lawv puas tuaj yeem qhia koj txog cov ntaub ntawv calibration kawg ntawm lub cub tawg-thiab ua pov thawj tias nws npog tag nrho qhov kub thiab txias siv rau koj qib?
- Lawv puas ua metallographic cross-section ntawm ntau lawm, tsis yog R & D khiav?
- Thaum ib daim duab hu tawm "Ra ≤0.4 µm ntawm qhov chaw sib khi," lawv puas tshuab * tom qab * sintering - lossis cia siab rau cov polishing thib ob uas tshem tawm cov txheej txheem tawv?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb yog rau tag nrho peb. Tsis yog raws li kev thov kev lag luam - tab sis raws li cov ntaub ntawv kev coj ua, pom hauv peb txoj kev tshawb xyuas ISO 9001 thiab sib qhia qhib thaum lub sijhawm tshuaj xyuas engineering. Peb tsis muag muaj peev xwm. Peb muag kev kwv yees.
Rau kev thov cov ntawv thov uas stainless hlau MIM yuav tsum xa ob qho tib si precision thiab kev ntseeg siab, koom tes nrog a hlau txhaj molding stainless hlau Hoobkas uas yog tus tswv ntawm tag nrho cov nqi saw-los ntawm kev tshawb fawb hmoov mus rau kev sim ua haujlwm-tsis yog qhov zoo dua. Nws yog tib txoj hauv kev uas zam kev rov tsim dua tshiab, ncua kev xa tawm, thiab kev ua tsis tiav. Lub neej yav tom ntej belongs rau cov tuam txhab uas kho metallurgy li engineering - tsis yog outsourcing.
