Mainjiniya akamatchula gawo lomwe liyenera kukhala ndi ± 0.02 mm kulolerana, kupulumuka pa 400 ° C panjinga yotentha, ndi kukana kukokoloka kwa slurry - palibe malo ongoyerekeza. Ndiko kumene Investment casting foundry fakitale ndi chilango chotsimikiziridwa chazitsulo chimapangitsa kusiyana pakati pa kulephera kumunda ndi moyo wautumiki wa zaka 15. Tadziwonera tokha: nyumba yapampu ya hydraulic inasweka pa 8,000 psi panthawi yovomerezeka-osati chifukwa cha mapangidwe, koma chifukwa cha microstructure yomwe ili ndi porosity yosazindikirika pafupi ndi mpando wa valve. Kukonzekera sikunali kukonzanso. Zinali kusintha kwa wothandizana naye yemwe amawongolera chemistry ya alloy melt, chinyezi chowumitsa zipolopolo, ndi mitengo yothira phula - osati "zigawo zotayira," koma zopangira uinjiniya.
Kulondola Kumayamba Kusanathire Koyamba
Kuwongolera kwenikweni kwa ndalama sikukwaniritsidwa mu ng'anjo. Zimayamba ndi traceability ndi ndondomeko repeatability. Pamalo athu ogwirizana ndi ISO ku Qingdao, gulu lililonse la cobalt-nickel alloy limakhala ndi zolembedwa zonse zotsimikizira kutentha-kuchokera kusanthula kwa ingot yaiwisi (AMS 5387, ASTM F75) mpaka pazotsatira zomaliza. Sitivomereza chemistry "yofanana". Timatsimikizira chromium, molybdenum, ndi mpweya wa carbon tisanathire - ndikuyika pazigawo zilizonse: kutentha kwa chipolopolo, nthawi yokhala ndi dewaxing, nthawi yonyowa isanakwane, komanso kuthamanga kwa vacuum yothandizira. Chifukwa chiyani? Chifukwa kupatuka kwa 2 ° C mu nkhungu preheat imasintha kulimba kokwanira kuti isinthe kagawidwe ka carbide m'malire ambewu mu T800-grade superalloys. Izi zimakhudza mwachindunji kukana kutopa m'nyumba za silinda za pampu ya pistoni zomwe zimadzaza ndi cyclic.
Tatsimikizira izi pamapampu 127 a AMS 5387 cobalt alloy 6 pampu. Magawo omwe adayikidwa pansi pazigawo zoyendetsedwa adawonetsa 31% moyo wotopa wocheperako poyerekeza ndi mawonekedwe ofanana a geometry pogwiritsa ntchito makonda apansi pashopu. Kusiyana sikunali kukonza - kunali kudziponya komweko.
Kuphatikizika Koyima Si Buzzword-Ndi Inshuwaransi Yamagawo
Otsatsa ena akumaliza kumaliza. Ena amawona kuponya ndi CNC ngati madipatimenti osiyana. Timawaphatikiza. Fakitale yathu yopangira zida zopangira ndalama imagwira chilichonse: kupanga zipolopolo za ceramic, kuponyera mwatsatanetsatane, chithandizo chochepetsera kupsinjika, makina a CNC amitundu yambiri (kuphatikiza ma 5-axis contouring of internal flow paths), ndi mankhwala ochizira pamwamba ngati HVOF tungsten carbide. Izi zimachotsa kusuntha kwapakatikati - mtundu womwe umatembenuza kulolerana kwa GD&T 0.015 mm kukhala 0.032 mm stack-up pambuyo pa ma handoffs atatu.
- Ma valve oponderezedwa amapangidwa mwachindunji kuchokera kuzinthu zopanda kanthu - palibe chowonjezera china chofunikira
- Maziko a pampu okhala ndi ma flange ophatikizika okwera ndi madoko amadzimadzi, onse amakhala ku ASME B16.34 Class 600 tolerances
- Zodzigudubuza za injini zamagalimoto opangira ma winch center shaft okhala ndi zomangira zolimba komanso zosatsimikizika zotsimikizika zapansi panthaka.
OEM yaku Europe ikafunikira ma nozzles a cobalt alloy m'malo mwa makina otsitsa othamanga kwambiri, omwe adawatumizira m'mbuyomu adapereka magawo omwe amafunikira 100% kukonzanso makina kuti akwaniritse zowunikira. Tidapereka magawo oyambira oyambira - chifukwa pulogalamu yathu ya CNC imawerengedwa mwachindunji kuchokera ku data ya as-cast CT scan, osati chitsanzo cha CAD.
Kuwongolera Ubwino Komwe Kumagwira Ntchito, Osati Kungolemba
"Kuyendera" sikukutanthauza kanthu ngati kudzachitika pamapeto pake. Dongosolo lathu labwino limayika chitsimikiziro pazigawo zinayi zosakambitsirana: certification yazinthu zomwe zikubwera, muyeso wa CMM wokhazikika pambuyo popanga makina ovuta, optical profilometry pamalo osindikizira ovuta, komanso kuyezetsa komaliza kogwira ntchito-kuphatikiza macheke akuwola pa 1.5 × kuthamanga kwa ntchito. Gawo lirilonse limalandira chizindikiritso chapadera cholumikizidwa ndi mbiri yake yonse ya digito: kusanthula kowoneka bwino kwa kusungunuka, curve ya mbiri yamafuta, lipoti lolumikizana la metrology, ndi mapu akukhaula pamwamba.
Tidakhala ndi makasitomala akufunsa kuti: "Kodi mungatsimikizire kuti zero porosity m'gawo la mpando wa valve?" Yankho ndi ayi-tikutsimikizira kuti tidzazindikiridwa. Ngati kusanthula kwathu kwa akupanga kukuwonetsa chilichonse choposa ASTM E1815 Level 2, timachotsa gawolo. Palibe kuchotserapo. Kulangidwa kumeneku kwapangitsa kuti chilema chathu cha PPM chikhale pansi pa 187 pazigawo zofunika kwambiri zama hydraulic m'miyezi 37 yapitayi.
Kutumiza Kwenikweni Padziko Lonse Si Nthawi Zolonjezedwa Zotsogola
Malonjezo a nthawi yotsogolera amatanthauza pang'ono ngati kuyitanitsa kwachitsanzo kumayimitsidwa kwa masiku 11 kudikirira chiphaso. Timasunga zovomerezeka za AMS 5387, F75, ndi zitsulo zosapanga dzimbiri 17-4PH m'matenthedwe angapo-ndi malipoti athunthu oyesa mphero pafayilo. Pama projekiti achangu, titha kuyambitsa kupanga zipolopolo mkati mwa maola 48 kuchokera pakuvomereza kujambula. Kuyenda kwathu kowonda kumatsata WIP kudzera pa ma siginecha a Kanban-osati maspredishithi-ndipo nthawi yathu yotumizira ma oda apakati (50-500 pcs) imayima pa 98.4%, yotsimikiziridwa ndi kafukufuku wazinthu zachitatu ku North America ndi kutumiza ku EU.
Wopanga pampu wina wakumwera chakum'mawa kwa Asia adachepetsa mtengo wofikira ndi 22% atasinthana nafe-osati chifukwa mtengo wathu watsika, koma chifukwa adachotsa magawo atatu oyendera, adadula zinyalala kuchokera pa 14% mpaka 0.9%, ndikupeza mayankho opangira-pa-kupanga musanayambe kudzipereka.
An Investment casting foundry fakitale sichimakhulupirira timabuku, koma ndi ma microstructures obwerezabwereza, mbiri yakale ya kutentha, ndi kukhazikika kwapakati pa 10,000. Zigawo zachitsulo zolondola sizilekerera kusamveka bwino. Ifenso sititero. Ngati gawo lanu lotsatira likufuna zambiri kuposa kulolerana mwadzina - ngati liyenera kuchita pomwe kulephera sikungatheke - yambani ndi njira yopangira, osati kugula.
