Akatswiri akamatchula zida zomangira zitsulo zama hydraulic valves kapena ma nozzles apampu a cobalt-alloy, samangosankha chakudya - akubetcha kukhazikika, moyo wotopa, komanso kukana dzimbiri pamalangizo azitsulo a wogulitsa. Zosaka zambiri za "fakitole zomangira zitsulo zazitsulo" zimaloza kwa opanga ufa wamba. Koma magwiridwe antchito adziko lapansi amadalira china chake chosowa kwambiri: mnzake yemwe amalumikiza chemistry yaufa, mawonekedwe a sintering, komanso kutsimikizika kwa gawo logwira ntchito, osati mu labu mokha, koma mkati mwa mpope wa pisitoni mumapalasa njinga pa bar 350.
Chifukwa Chake Kusasinthasintha kwa Feedstock Kumaswa—kapena Kumapanga—Gawo Lanu la MIM
Tawonapo mapangidwe atatu ofanana a AMS 5387 a cobalt alloy nozzle akulephera kuyenerera m'magulu osiyanasiyana - osati kuchokera ku zolakwika zamapangidwe, koma kuchokera pakusintha kosawoneka bwino kwa okosijeni ndi kukula kwa tinthu muzodyetsa. Gulu limodzi linawonetsa 12% yapamwamba kwambiri pambuyo pa debinding; china chinayambitsa microcracking pa HIP. Chifukwa chake? Ufa wopangidwa kuchokera ku mphero zitatu zosiyana, iliyonse ili ndi ndondomeko zowunikira za sieve zosagwirizana komanso kusagwirizana kwa oxide pamwamba. Kusasinthika kowona kumayamba kusanasakanizidwe: kutsimikizika kwazinthu zopangira, zolembedwa za atomization ya gasi, ndi malipoti owunikira kutentha kwa batch-to-batch - osati ziphaso zowunikira zomwe zidasindikizidwa "zimagwirizana ndi ASTM B243."
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amasamalira feedstock ngati njira yosinthira, osati chinthu. Fakitale yawo yopangira jakisoni wazitsulo sikuti imangopereka ufa - imatsimikizira momwe gawo lililonse limachitira pansi pa makina awo omangira, kutsekereza mbiri, komanso mlengalenga. Amayang'ana kachulukidwe ka pre-sinter ndi mapu ocheperako otentha pagawo lililonse lomwe likubwera. Ichi ndichifukwa chake zigawo zawo za T800 zochokera ku MIM zimakhala ndi ± 0.05 mm kulolerana kwa 120 mm popanda makina achiwiri - ndi chifukwa chake makasitomala awo amanena kuti zero zalephera pa mapulagi a cobalt alloy omwe amagwira ntchito m'madera a mpweya wowawasa kwa miyezi yoposa 18.
Kuchokera ku Powder kupita ku Pressure Valve: Kumene Kuphatikizika Koyima Kumathetsa Kulingalira
Otsatsa ena amapereka magawo obiriwira a MIM ku nyumba za gulu lachitatu. Ena amapereka chithandizo cha kutentha kapena kugaya komaliza. Chiwopsezo chilichonse chimawonjezera kusatsimikizika: kusuntha kwa kutentha, kuipitsidwa kwamadzi kumalowera, GD&T callouts drift. Ku QINGDAO QIANGSENYUAN, gulu lomwelo lomwe limasankha ufa limapanganso mapulogalamu a CNC grinders kumaliza pamwamba pa mpando wa valve-ndi zizindikiro pa lipoti lomaliza la CMM.
- Amayika njira zoyambira zopangira ndalama pogwiritsa ntchito zida zotayika za thovu zokongoletsedwa ndi mipanda yopyapyala ya MIM geometries
- Amawotchera m'ng'anjo za vacuum ndi kuwunika kwenikweni kwa mpweya wa oxygen - osati kutentha kokha.
- Amapanga maulendo a HIP ndi zolembedwa zotsika mtengo komanso nthawi yokhalamo, kenako amatsimikizira kachulukidwe kudzera pa Archimedes ndi microstructure kudzera pa SEM-EDS.
- Amamaliza malo osindikizira ovuta ndi kutembenuka kwa diamondi imodzi-osati kuphulika koopsa-kuteteza malire a tirigu.
Izi sizongoyerekeza. Pampu yapampu ya ku Europe OEM ikafunika m'malo mwa makina opangidwa ndi AMS 5387 valve valve, inkafuna ≤0.3% kusiyanasiyana kwa kachulukidwe pamayunitsi 500. QINGDAO QIANGSENYUAN idapatuka ndi 0.18% -ndipo adatsata aliyense wotuluka ku ng'anjo imodzi yowongoleredwa yomwe idagwidwa potsimikizira kutsimikizira kwa thermocouple.
Kodi “Kuchita Bwino Kwambiri” Kumatanthauza Chiyani M’zochita
"Kuchita bwino" kumagwiritsidwa ntchito molakwika. Zinthu zimatha kupirira mayeso okhazikika - koma zimalephera pakutopa kwakanthawi. Ikhoza kukana kupopera mchere-koma kumawononga pansi pa galvanic kugwirizana ndi zipangizo zosapanga dzimbiri. Kuchita kwenikweni kumakhala muzochitika zogwiritsira ntchito.
Ichi ndichifukwa chake fakitale ya QINGDAO QIANGSENYUAN yazitsulo zomangira jekeseni yazitsulo imaphatikiza akatswiri opanga ntchito - osati akatswiri azitsulo okha - mu ndemanga zamakasitomala. Samafunsa "Mukufuna alloy yanji?" Amafunsa kuti: "Kodi makina anu amawona kuthamanga kwakukulu kotani? Kodi pH yamadzimadzi poyambitsa ndi yotani? Ndemanga zawo pakupanga zinthu zikuphatikizapo machenjezo monga: "Utali wa 0.2 mm pamphuno udzatseketsa zotsalira za binder-timalimbikitsa kuwonjezeka kufika ku 0.35 mm kapena kusinthana ndi zosungunulira," kapena "kukula kwa tirigu wa T800 pamwamba pa 1220 ° C kudzasokoneza kukana kwa chimfine apa-tiyeni tisinthe mawonekedwe a sintering."
Atumiza magawo opitilira 17,000 a MIM amafuta akunyanja & gas winch center shaft rollers kuyambira 2021. Chigawo chilichonse chimakhala ndi traceability yokwanira - nambala ya batch, ID ya sintering log, satifiketi yozungulira ya HIP, komanso kuwerenga komaliza. Palibe kuchotserapo.
Kusankha Bwenzi Lanu Sizokhudza Timabuku—Ndi Umboni
Ngati polojekiti yanu yotsatira ya MIM ikuphatikiza ma aloyi a cobalt-nickel, malo osindikizira kwambiri, kapena ma geometries omwe safunikira. kulondola kwa dimensional pansi pa katundu wotentha, dumphani kufananitsa kwamakatalo. Funsani m'malo mwake:
- Kodi mungagawane nawo ma rekodi atatu omaliza owongolera ng'anjo yamoto?
- Kodi mumasunga zithunzi za SEM zosungidwa zakale ndi mamapu a EDS pazambiri zokanidwa?
- Kodi mumatsimikizira bwanji kutenthedwa kwa binder - ma curve a TGA kapena kuwonda kwenikweni pagawo lililonse?
- Kodi kusiyana kwanu koipitsitsa kwambiri ndi chiyani pa gawo la 100 mm m'mimba mwake - ndipo mumalipira bwanji pakupanga zida?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha zonse zinayi—pa pempho, ndi deta. Tsamba lawo https://www.tsingtaocnc.com imakhala ndi malipoti otsitsa oyeserera, osati zithunzi zokha. Mphamvu zawo si zazikulu-ndi kuwunika. Osati voliyumu - ndikutsimikizira.
Pazinthu zamafakitale zolondola pomwe kulephera kumatanthauza nthawi yocheperako, chiwopsezo chachitetezo, kapena kusagwirizana ndi malamulo, fakitale yoyenera yopangira jakisoni wazitsulo sikuti imangopereka ufa. Zimapereka umboni.
