Lub ntiajteb txawj nqus mus tas li pwm casting Hoobkas kev daws teeb meem xav tau ntau tshaj li molten hlau thiab hlau pwm. Lawv xav tau kev tswj xyuas kom zoo, kev tswj pwm rov ua dua lub neej, thiab kev qhuab qhia metallurgical-tshwj xeeb tshaj yog thaum tsim cov khoom siv siab ncaj ncees rau cov twj hydraulic, oilfield li qub, lossis engineering tsheb winch systems. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau nrum ntau tshaj 12,000 lub siab-rated hlau thiab steel qhov chaw nyob rau hauv pwm mus tas li txij li thaum 2018 - thiab txhua qhov tsis ua hauj lwm, txhua qhov seem drift, txhua qhov kev tshwm sim micro-shrinkage qhia peb ib yam: gravity casting tsis passive pouring. Nws yog tswj solidification.
Vim li cas Permanent Pwm Gravity Casting tseem yeej rau nruab nrab-Volume Industrial Parts
Qee tus engineers xav tias peev casting hloov lub ntiajteb txawj nqus mus tas li pwm casting. Tab sis hauv kev tsim khoom tiag tiag - tsis yog qhov chaw kuaj mob - pwm tas mus li muab cov kev sib tw nruj dua rau cov vaj tsev zoo li piston twj tso kua mis lub tog raj kheej thaiv thiab lub siab valve lub cev. Vim li cas? Vim tias pwm kub nyob hauv ± 5 ° C hla 300+ cycles thaum siv preheated, coated H13 cuab yeej steel pwm. Xuab zeb casting tsis tuaj yeem phim qhov kev ruaj ntseg. Kev nqis peev casting qhia txog ceramic plhaub variability thiab siab dua residual stress. Peb ntsuas nws: ntawm 420 hli × 280 hli × 120 hli twj tso kua mis foundation casting, ruaj khov pwm tuav GD&T txoj hauj lwm kam rau ua rau ± 0.15 hli tshaj 500 units; xuab zeb casting nruab nrab yog ± 0.32 hli, nrog 17% seem vim yog cov tub ntxhais hloov.
Peb khiav ob lub ntiajteb txawj nqus mus tas li pwm kab-ib qho rau cov hlau hlau (ASTM A), ib qho rau cov hlau tsis tshua muaj hlau (A105N). Ob leeg siv cov qhov rooj hauv qab-ntws, txias ntxig rau ntawm qhov chaw tseem ceeb, thiab kev saib xyuas lub sijhawm ntawm lub sijhawm ntawm cov pwm kab noj hniav. Tsis muaj kwv yees. Tsis muaj "standard" lub sij hawm voj voog. Txhua feem muaj nws tus kheej solidification profile mapped nyob rau hauv peb cov txheej txheem validation cov ntaub ntawv.
Qhov twg Feem ntau Factories Fail - thiab Yuav Ua Li Cas Peb Kho Nws
Feem ntau lub ntiajteb txawj nqus pwm casting Hoobkas ua haujlwm poob ntawm peb lub ntsiab lus: pwm degradation, inconsistent preheat, thiab tsis txaus riser tsim rau alloy-specific noj. Peb pom qhov no ua ntej ntawm AMS 5387 cobalt alloy twj tso kua mis vaj tsev txiav txim. Thawj 19 castings pom cov av porosity nyob ze ntawm lub flange-txawm tias zoo meej chemistry. Hauv paus ua rau? Pwm nto oxidation tom qab 42 lub voj voog hloov cov cua kub rho tawm. Kev daws: peb tam sim no recondition pwm txhua 35 txhaj tshuaj siv alumina blasting thiab proprietary borosilicate txheej - txheeb xyuas los ntawm infrared emissivity kuaj ua ntej txhua ncuav.
Peb kuj tswj hwm nruj preheat kev qhuab qhia. Peb cov pwm yeej tsis nkag rau hauv qhov cub txias. Lawv tsau ntawm 280 ° C rau 90 feeb, ces nce mus rau 320 ° C ± 3 ° C thiab tuav rau 45 feeb - ntsuas ntawm peb qhov tob. Qhov ntawd tsis yog-negotiable. Hla nws, thiab koj tau chwv cov kab nrib pleb lossis misruns hauv T800-based Cheebtsam. Cov neeg muas zaub uas muab lawv tus kheej pwm feem ntau saib qhov no. Peb sim lawv ua ntej txais.
Kev koom ua ke yog qhov txiaj ntsig tiag tiag-tsis yog Casting xwb
Qhov tseeb lub ntiajteb txawj nqus mus tas li pwm casting Hoobkas daws tsis nres ntawm lub shakeout. Nws txuas ntxiv los ntawm kev siv tshuab, kev kho cua sov, thiab kev ntsuas - tag nrho hauv ib lub ru tsev. Ntawm peb qhov chaw Qingdao, lub tog raj kheej lub tog raj kheej txav ncaj qha los ntawm kev tshem tawm pwm mus rau CNC tig rau Mazak Integrex i-200S. Tsis muaj logistics ncua. Tsis muaj kev puas tsuaj. Tsis muaj kev tswj hwm qhov system pib dua. Peb tshuab bores tseem ceeb thaum lub casting tseem nyob rau hauv 50 ° C ntawm solidus kub-txo distortion los ntawm 40% piv rau chav-kub machining.
Peb ntsug kev koom ua ke npog plaub txheej: cov ntaub ntawv pov thawj (tag nrho cov heats traceable rau zeb xeem cov ntaub ntawv), casting txheej txheem validation (nrog radiographic thiab ultrasonic sampling ib ASME B16.34), precision machining (CMM-tshuaj xyuas rau ISO 2768-mK), thiab functional testing (hydrostatic pressure tests mus txog 450 bar onrig). Yog vim li cas peb winch center ncej chais rau off-highway tsheb ua tau 100% first-pass yield-txawm tias tsis-tus qauv tapers thiab cuam tshuam qhov chaw.
Xaiv koj tus khub tsis yog hais txog nqe-Nws yog hais txog kev kwv yees
Yog tias koj qhov project xav tau lub ntiajteb txawj nqus mus tas li pwm casting Hoobkas uas thauj khoom raws sijhawm, tuav GD&T yam tsis muaj kev sib cav, thiab chij kev pheej hmoo ntawm kev tsim khoom ua ntej pib siv-koj xav tau cov ntaub ntawv muaj peev xwm, tsis yog kev lag luam thov. Nug peb lo lus nug no ua ntej kos npe:
- Koj puas tuaj yeem qhia kuv txog peb lub pob PPAP kawg - suav nrog cov ntawv kho pwm thiab kab noj hniav kub?
- Koj puas ua cov txheej txheem spectrographic tsom xam ntawm txhua qhov cua sov, lossis tsuas yog ntawm thawj kab ntawv?
- Thaum qhov kev ua tsis tiav NDT, koj puas muab daim ntawv qhia txog kev kho - lossis tsuas yog rov ua dua?
Peb ua tag nrho peb. Txhua lub sijhawm. Peb ISO 9001: 2015-certified system taug qab txhua pwm txhaj, txhua raw khoom ntau, txhua CMM sojntsuam taw tes. Tsis muaj kev zam. Qhov ntawd yog li cas peb txhawb cov neeg siv khoom thoob plaws North America, Lub Tebchaws Yelemees, thiab Singapore - nrog xoom xa khoom lig ntawm cov xaj nruab nrab hauv 2023.
Saib tom ntej, peb tab tom nthuav peb lub ntiajteb txawj nqus pwm mus tas li pwm casting Hoobkas muaj peev xwm rau hauv cov txheej txheem hybrid: ze-net-puab puab pwm castings tiav nrog laser-pab CNC milling rau cobalt-nickel alloys. Tsis yog vim nws yog qhov tshiab-tab sis vim cov ntaub ntawv hauv teb qhia tias nws txo tus nqi tag nrho los ntawm 22% ntawm cov khoom uas xav tau ob qho tib si geometry thiab hnyav hnyav hnyav. Precision tsis yog chav haujlwm. Nws yog qhov sib lawv liag.
