Pamene mainjiniya amafunika zitsulo jekeseni akamaumba ntchito fakitale kuthandizira zigawo zomwe ziyenera kupirira ± 0.01 mm pansi pa 300-bar hydraulic pressure-kapena kupulumuka 800 ° C kutentha kwapang'onopang'ono m'matupi a valve valve-sayamba ndi RFQ yachibadwa. Amayamba ndi khalidwe lakuthupi, kugawa kupsinjika maganizo, ndi njira zenizeni zolephera. Taziwonapo: mphuno ya cobalt-nickel idasweka pakuyesa kumunda-osati kuchokera ku zolakwika zamapangidwe, koma chifukwa chopangidwa ndi as-sintered microstructure chinalibe kugwirizana kwa malire. Ndipamene "wothandizira wina wa MIM" amasiya kukhala othandiza.
Chifukwa Chake-Kulondola Kwambiri MIM Ikufuna Zambiri Kuposa Ufa + Press
Metal Injection Molding si CNC Machining. Ndi metallurgy obisika ngati kupanga. Mumadyetsa ufa wachitsulo wabwino (nthawi zambiri <20 µm), amange ndi sera ya thermoplastic, jekeseni mubowo, debind, kenaka sinter pa kutentha pafupi-kusungunuka. Gawo lirilonse limasintha kachulukidwe, kukula kwambewu, komanso kupsinjika kotsalira. Kusintha kwa 0.3% pazakudya za kaboni mu AMS 5387 cobalt alloy? Izi zimasintha kuuma kuchokera ku 42 HRC kupita ku 48 HRC-ndikupha moyo wotopa m'nyumba zapampu ya piston. Tatsimikizira izi pazambiri zopanga 17. Mafakitole ambiri amawona MIM ngati "pafupifupi-net-shape casting." Njira yabwino kwambiri ndiyo kusinthika kwa gawo lokhazikika.
Ndicho chifukwa chake kulondola kwenikweni kumayambira musanayambe kuwombera koyamba. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., projekiti iliyonse ya MIM imayamba ndi macheke atatu osakambitsirana: chiphaso chazinthu zopangira (ASTM F2885 ya ma aloyi a cobalt), kuwunika kwapang'onopang'ono (osati nthawi/kutentha kokha-koma kutayika kwa misa pa ° C), ndi kuwongolera mame<−40°C). Dumphani imodzi, ndipo mudzapeza magulu a porosity pamizu ya ulusi kapena kutengeka kozungulira muzitsulo zopyapyala zapampu. Sitimapereka zowongolera izi. Amamangidwa m'malo athu ogwirizana ndi ISO ku Qingdao-kumene mizere ya MIM imayendera limodzi ndi ma cell a CNC okhala ndi ma axis asanu ndi ng'anjo zochizira kutentha kwa vacuum.
Kumene Makampani Okhazikika a MIM Agunda Khoma Lawo-ndi Momwe Timawolokera
Makasitomala ena amafunsa kuti: "Kodi mungapange gawo la T800 cobalt alloy kudzera ku MIM?" Yankho lathu si inde kapena ayi. Ndi: *Kodi njira yolemetsa yogwira ntchito ndi yotani?* Pulagi yosazungulira? Inde—MIM imapereka kachulukidwe kokwanira komanso mphamvu ya isotropic. Chogudubuza chapakati cha shaft chothamanga kwambiri cha winchi yamagalimoto a engineering? Ayi—MIM yokha siingathe kutsimikizira kukhulupirika kwapansi pa nthaka yofunikira pakutopa kozungulira kwa 500,000. Apa ndipamene kukonza kosakanizidwa kumayambira: mawonekedwe a MIM + omaliza-makina okhala ndi makina + kuuma kwa laser pazigawo zolumikizana.
Izi sizongoyerekeza. Tidapanga magawo 12,400 a AMS 5387 chaka chatha pogwiritsa ntchito ndondomekoyi. Zokolola: 98.7%. Kukana chifukwa chake? Magawo awiri adalephera kutsimikizika kwa CMM pakukhazikika - osati chifukwa cha kuchepa kwa sintering, koma chifukwa gawo lobiriwira lidapunduka pogwira ntchito musanamange. Kotero ife tinapanganso thireyi yothandizira ceramic. Kubwereza kwadziko lapansi kumaposa malonjezo amtundu uliwonse nthawi zonse.
- Cobalt-nickel MIM magawo: AMS 5387, T800, L605-kufufuza kotsimikizika kuti kusungunuke batch
- Dimensional control: ± 0.3% kulolerana kwa mzere wocheperako, kutsimikiziridwa pa ASME Y14.5 GD&T
- Umphumphu pamwamba: Monga-sintered Ra ≤ 3.2 µm; pambuyo-makina Ra ≤ 0.4 µm pa malo ovuta kusindikiza
- Kutsimikizira kogwira ntchito: Kuyesa kukakamiza ku 1.5 × kukakamiza kugwira ntchito, kuyesa kwa helium <1×10⁻⁹ mbar·L/s
Osati "Mwambo" Onse Amatanthauza "Kulamulidwa" - Izi ndi Zomwe Zimasuntha Singano
"Mwambo" umagwiritsidwa ntchito molakwika. Fakitale yomwe imasintha malo omwe ali pachipata kapena kusintha nthawi ya sintering ikuchita mwamakonda. Fakitale yomwe imapanga gawo lanu lakukulitsa kwamafuta ndi envulopu yoyendetsera dongosolo lanu ikuwongolera. Timachita zomaliza.
Mwachitsanzo: nyumba ya valve yokakamiza imafunikira zero kukula kwa kutentha kosagwirizana pakati pa thupi lachitsulo chosapanga dzimbiri ndi choyikapo mpando wa cobalt alloy. Standard MIM ikanapanga kusiyana kwa 7.2 ppm/°C—kokwanira kuchititsa kutayikira pa 120°C. Yankho lathu? Gradient sintering-kutsika kwa kutentha kwa malo a mpando, pamwamba pa makoma apangidwe-kuphatikizapo post-sinter-stress-relief annealing. Zotsatira: kusagwirizana kwachepetsedwa kufika pa 0.9 ppm/°C. Kutsimikiziridwa ndi mapu amtundu wa digito image correlation (DIC).
Mlingo wolowererawu umangogwira ntchito ndi kuphatikiza koyima. Ndife eni ake a labu yowonetsera ufa, zombo za ng'anjo ya sintering, CMM metrology suite, ndi mzere womaliza. Palibe ma handoffs. Palibe mipata ya data. Gulu limodzi lokha la mainjiniya lomwe limatsata zomwe zili ndi okosijeni, mawonekedwe a pore, ndi mphamvu zolimba kuchokera pa ID ya lot kupita ku chiwonetsero cha kutumiza.
Kusankha Fakitale Yanu Yazitsulo Zopangira Majekeseni Sizokhudza Kutha - Ndi Za Context
Ngati gawo lanu likugwira ntchito m'ma hydraulic system, zida zamafuta & gasi, kapena zida zopopera zapamwamba-ndipo zimafuna ma alloys a cobalt, GD&T yolimba, kapena kutsimikizika kogwira ntchito mopitilira miyeso yosindikiza-mumafuna zambiri kuposa wogulitsa. Mukufunikira mnzanu amene amalankhula zitsulo bwino, amachitira sintering ngati chemical reaction, ndipo amayesa kupambana ndi kulephera kwa m'munda-osati kupindula koyamba.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga luso limenelo tsiku ndi tsiku. Osati monga malonda a malonda-koma monga mapepala olembedwa, malipoti a kafukufuku wa chipani chachitatu, ndipo 237 anatumiza zinthu zambiri zomwe sizinali zamtundu wa MIM kuyambira Q1 2023. Chotsatira sichikupempha mtengo. Ikutumiza zojambula zanu za GD&T kuti ziwunikirenso kupangika - popanda mikangano ya NDA, zongoyerekeza zanthawi yotsogola, komanso kusalolera zongopeka.
Chifukwa pakupanga jekeseni wazitsulo wolondola kwambiri, kusiyana pakati pa "ntchito" ndi "sikulephera" kumayesedwa mu ma microns, mphindi, ndi sayansi yakuthupi-osati mawu otsatsa malonda.
