Izingxenye Zensimbi Ezisikiwe Zezokwelapha Ezisezingeni Eliphezulu

Metal powder umjovo ukubumba(MIM) inqubo entsha yokukhiqiza ehlanganisa i-powder metallurgy nezinqubo zokubumba zepulasitiki. Kubandakanya ukuxuba impushana ekhethiwe nge-binder, bese uhlanganisa ingxube bese uyijova ngendlela oyifunayo. I-polymer idlulisela izici zayo zokugeleza kwe-viscous ekuxubeni, okubuye kube nomthelela ku-homogeneity yokubunjwa, ukugcwaliswa kwe-cavity kanye nokulayisha i-powder. Ngemuva kokwakhiwa, i-binder iyasuswa bese izikhala ezihlutshiwe zibe sezicwiliswa. Eminye imikhiqizo ye-sintered ingase ibe ngaphansi kokuminyana okwengeziwe, ukwelashwa ngokushisa noma ukwenziwa ngomshini. Umkhiqizo we-sintered awugcini nje ngokuba nesimo esiyinkimbinkimbi esifanayo kanye nokunemba okuphezulu njengomkhiqizo obunjwe ngomjovo wepulasitiki, kodwa futhi unezici ezibonakalayo, zamakhemikhali nezomshini eziseduze nalezo zengxenye efojiwe. Lobu buchwepheshe benqubo bufanele ukwenziwa kwezingxenye ezincane, ezinembile, ezinezinhlangothi ezintathu ezinobumo obuyinkimbinkimbi kanye nezidingo zokusebenza ezikhethekile ekukhiqizeni umthamo ophezulu.

Izindawo zokufaka izicelo zobuchwepheshe be-MIM

Izinhlelo zokusebenza ezijwayelekile
Imboni ye-Aerospace: izintambo zamaphiko endiza, imibhobho yerokhethi, amaphiko omsila we-missile, ama-ceramic turbine blade cores;
Imboni yezimoto: izingxenye zokhiye wokulawula ukuthungela, ama-turbocharger rotor, iziqondiso zamavalvu, izingxenye zamabhuleki ezimoto, izakhi zokuvikela ilanga zezimoto;

Imboni ye-elekthronikhi: izingxenye ze-disk drive, izixhumi zekhebula, izindlu zamashubhu kagesi, amakhanda okuphrinta amakhompyutha, amaphakheji e-electronic, izinto zokucwilisa ukushisa;

Imboni yezempi: ama-rotor asemayini, izimbangi zamapuleti ezibhamu, izinhlamvu zezinhlamvu ezibhoboza izikhali, ama-collimator, imicibisholo emincane yama-projectiles eqoqo;
Imishini yezokwelapha: abakaki be-orthodontic, ama-sutures angaphakathi, ama-biopsy forceps, izivikelo zemisebe;
Imikhiqizo yasendlini: amakesi ewashi, izintambo zewashi, izixhumi zewashi, izinhloko zegalofu nezibambi, amabhande ezicathulo zemidlalo, izingxenye zezibhamu zezemidlalo, izibophezelo zemibhalo nezimbobo zokubhoboza;

Imboni yemishini: abasiki bokugaya abamise, amathuluzi okusika, amagiya amancane;

Izinzuzo ze-MIM

I-1, izinga eliphezulu lenkululeko yengxenye yejometri, ngesinye isikhathi yakha ukukhiqizwa kwezingxenye zensimbi ezinokwakheka okuyinkimbinkimbi;

I-2, imikhiqizo ye-MIM inobuningi obufanayo, isiphetho esihle, ukuhwaqeka kwendawo kungafinyelela ku-Ra 0.80 ~ 1.6μm, ububanzi besisindo bungu-0.1 ~ 200g. ukunemba okuphezulu kwe-dimensional (±0.1% ~ ± 0.3%), ngokuvamile ngaphandle kokucubungula okulandelayo;

I-3, inhlobonhlobo yezinto ezisetshenziswayo, izindawo ezibanzi ezisetshenziswayo, izinga eliphezulu lokusetshenziswa kwezinto ezingavuthiwe, izinga eliphezulu lokuzenzakalela kokukhiqiza, izinqubo ezilula, ukukhiqizwa ngobuningi okuqhubekayo kungafinyelelwa;

I-4, ikhwalithi yomkhiqizo ozinzile, ukusebenza okuthembekile, ukuminyana okuhlobene kwemikhiqizo kungafinyelela ku-95% kuya ku-99%, kungenziwa nge-carburized, kucinywe, kufakwe umoya kanye nokunye ukwelashwa kokushisa. Imikhiqizo inezakhiwo eziphakeme zemishini njengamandla, ubulukhuni nobude, ukumelana nokugqokwa okuhle, ukumelana nokukhathala kanye nenhlangano efanayo;
