Apo mainjiniya anotsanangura simbi isina tsvina yekumusoro-chaiyo, mishoni-yakakosha zvikamu-funga kumanikidza mavharuvhu mu hydraulic masisitimu kana piston pombi humburumbira housings-vanoda zvinopfuura kungoita ngura. Vanoda kugadzikana kwedimensional pasi pekupisa bhasikoro, microstructural kutendeseka mushure mekunyungudika, uye kupera kwepamusoro kunopona abrasive kuyerera midhiya. Ndiko uko kwakatsaurirwa simbi jekiseni kuumba Stainless simbi fekitari inova isingagone kutaurirana-kwete semutengesi, asi semubatsiri wehurongwa.
Nei MIM Stainless Simbi Ichida Kubatanidzwa Kwakatwasuka—Kwete Chete Zvishandiso
Isu takaona mapurojekiti akawanda achimira padanho reiyo prototype nekuti shopu yeMIM yaibata feedstock kusanganisa uye kubvisa, asi yakadhirowewa sinter kune general-chinangwa opareta. Stainless simbi mamakisi senge 17-4 PH kana 316L kuita zvisingafungidzike pasina kudzora kwakasimba pamusoro peokisijeni chikamu chekumanikidzwa, mareti erempu, uye nguva dzekubata panguva yekupisa. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., iyo yose yeMIM yekufambisa-kubva pakugadzira feedstock ine yakasimbiswa Stainless simbi poda (ASTM A985-inopindirana), kuburikidza ne solvent uye thermal debinding, kuti vacuum-sintering mu ISO 9001-certified mavira pasi-inoitwa pasi pedenga rimwe. Hapana handoffs. Hapana batch-to-batch musiyano mukukura kwezviyo. Hapana zvinoshamisa apo GD&T callouts inoda ± 0.02 mm pane dzakatetepa-madziro maficha asingasviki 1.2 mm mukobvu.
Uku kubatanidzwa kunonyanya kukosha kana geometry inosangana nebasa. Winch centre shaft roller yemotokari dzeinjiniya inoda kuomarara ≥38 HRC *uye* kushata kwepamusoro kweRa ≤0.8 µm—zvinodiwa zvinomanikidza kutengeserana pakati pe sintering density uye post-MIM machining. Nzvimbo yedu mabhiriji ayo gaka: isu sinter padhuze-net-chimiro, tobva yashandisa multi-axis CNC kupedzisa neyakasanganiswa kupisa kurapwa-hapana ekunze logistics, hapana gadziriso zvikanganiso, hapana kurasikirwa kwekuenderera kwedatum.
Iko Kunokundikana MIM Yakajairwa — uye Magadzirirwo eNyaya-Chaiyo Nyanzvi
Vamwe vanogona kupokana kuti chero mupi weMIM anogona kugadzira simbi isina tsvina kana vakatevera ASTM F2885. Asi chaiyo-nyika yekutadza modes inotaura imwe nyaya. Isu takatsvaga kuputika kwakadzokororwa muzvigaro zve316L mavharuvhu kumashure kune zvakasara binder kabhoni yakavharirwa pamiganhu yezviyo-chikanganiso chisingaoneki nekutarisa kwemaziso asi njodzi pasi pekumanikidzwa kwecyclic. Kugadzirisa kwakanga kusiri kukurumidza kubvisa; yakanga ichichinja kubva paparafini-yakavakirwa kune polyacetal-based binders *uye* ichiwedzera inodzorwa mamiriro epamberi pre-sinter soak nhanho. Kugadziridzwa ikoko kwakabva kumakore gumi nemaviri ekushandisa AMS 5387 cobalt alloy nozzles-midziyo ine zvakafanana kudziya kwekuwedzera senitivity asi kudhura kwezvirango zvezvakaraswa.
Chiitiko ichocho chinotamisa zvakananga kusimbi isina tsvina. Metallurgists edu haatore 17-4 PH se "rimwe giredhi." Ivo vanoziva mhinduro yayo yekuchembera inoshanduka kana tembiricha yekunyura ikadonha ± 5 ° C. Vanoona hupfu hwese hunouya neOES ongororo-kwete chete yeFe/Cr/Ni, asi yekutsvaga oxygen nenitrogen inotonga pore morphology. Uye ivo vanonyora yega yega parameter: dova rinenge riri mukamuri yekupisa, kumhanya kwebhandi muovheni inovhara, kunyangwe hunyoro hwepakati panguva yekubata kwegirinhi chikamu. Nokuti mumagungano epombi epamusoro-soro, 0.3% density yakasiyana haisi yezvinyorwa-kutadza kuneta nguva isati yakwana pa12,000 psi.
Kubva pakudhirowa kusvika pakuendesa: Chii "High-Precision" Zvinonyatsoreva Mukuita
"High-precision" inoshandiswa zvisizvo nguva dzose. Kurongeka kwechokwadi kunoreva kudzokororwa kwe500+ zvikamu, kwete chete CMM scan. Zvinoreva kubata chinzvimbo chechokwadi paØ3.2 mm maburi ari 42 mm kureba mukati me 0.015 mm—*mushure me* sintering shrinkage, *mushure me* kuzorodza pfungwa, *mushure me* passivation. Heano maitiro atinozviita:
- Incoming control: Mbishi simbi isina hupfu yakayedzwa kugovera saizi yechikamu (D50 ≤ 8.5 µm), kujeka kwehunyoro, uye chiyero chekuyerera paASTM B212
- In-process verification: Green chikamu uremu Logged per mhango; sintered density kuyerwa kuburikidza neArchimedes nzira pane yekutanga-off uye yega yega 50th chikamu
- Kusimbisa kwekupedzisira: 100% CMM yekuongorora pane yakakosha datums; sarudza SEM/EDS pane kuputsika kwepamusoro pekuongorora pore
- Traceability: Imwe neimwe mijenya inotakura QR-coded chitupa chinobatanidza hupfu, sintering run ID, opareta log, uye yekupedzisira yekuongorora report.
Izvi hazvisi kuwandisa-ndiyo yekutanga kune vatengi muoiri & gasi vanoda kutevedzera ASME B31.4 kana EU PED 2014/68/EU zvinyorwa. Isu hati "wedzera zvitupa gare gare." Isu tinovaka sisitimu kutanga, tozoongorora tichipikisa.
Kusarudza Yako Metal Injection Molding Stainless Steel Factory—Tarisa Kare Bhurocha
Kana chirongwa chako chinotevera chinosanganisira simbi isina tsvina yeMIM zvikamu zve hydraulic manifolds, pombi nheyo, kana tsika cobalt-stainless mahybrids, bvunza mibvunzo mitatu usati wasaina PO:
- Vanogona here kukuratidza rekodhi rekupedzisira rekombi yevira-uye kuratidza kuti inovhara tembiricha yakazara inoshandiswa pagiredhi rako?
- Ivo vanoita metallographic cross-sections pamijenya yekugadzira, kwete R&D chete inomhanya?
- Kana mufananidzo ukadaidzira "Ra ≤0.4 µm panzvimbo yakavharidzirwa," vanogadzira * mushure * kunyura-kana kuti vanovimba nekuporiswa kwechipiri kunobvisa iyo yakaomeswa kesi layer?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. anopindura kuti hungu kune vose vari vatatu. Kwete sezvikumbiro zvekushambadzira-asi semaitiro akanyorwa, anoonekwa mune yedu ISO 9001 maitirwo ekuongorora uye akagovaniswa pachena panguva yekuongorora kweinjiniya. Hatitengesi capacity. Isu tinotengesa kufanotaura.
Nekuda kwekushandisa uko simbi isina Stainless MIM inofanirwa kuendesa zvese nemazvo uye kuvimbika, kubatana ne simbi jekiseni kuumba Stainless simbi fekitari iyo ine iyo yakazara kukosha cheni-kubva paupfu sainzi kuenda kune inoshanda yekuyedza-haisi mukana. Ndiyo chete nzira inodzivirira kugadzirisa zvinodhura, kunonoka kutanga, uye kutadza kwemunda. Ramangwana nderevagadziri vanobata simbi seinjiniya-kwete kuendesa kunze.
