Inqubo ye-MIM (metal injection molding) inqubo, okuwuhlobo olusha lwenqubo yokwenza ingxenye yensimbi ehlanganisa inqubo yesimanje yokubumba umjovo wepulasitiki kanyeinqubo yensimbi eyimpuphu. Le nqubo entsha yavela ngasekupheleni kwawo-1970 futhi ekuqaleni yayisetshenziselwa ukwenza izingxenye zezikhali ezilula. Kulokhu ngizokwethula ezimbalwaIzingxenye zokubumba umjovo wensimbi we-MIMokwezikhali.
I-JIEHUANG CHIYANG Inkampani ephezulu yokubumba umjovo wensimbi:
Izingxenye zokuqala ze-MIM: Izingxenye ze-MIM zokupakisha ngogesi. Le ngxenye yakhiwe nguUbuchwepheshe be-MIM (Metal Injection Molding)futhi yakhiwe izingxenye zebanga le-F15 (Ni-Co-Fe); ukubekezelelana kwembobo kuhlanganisa noma kususe 0.2mm. Lo mkhiqizo wokubumba umjovo wensimbi usetshenziselwa ukupakisha kwe-Opto-electronic. Enye yezidingo ukuthi ijika lokunwetshwa lezinto ezibonakalayo kufanele lifane nengilazi evaliwe.
Ikhasimende ligxile ekuhloleni ukusebenza kokuvalwa kwendawo ebiyelwe nge-elekthronikhi ye-MIM ngemva kokuba izingxenye zibhekane nokushaqeka okushisayo. Le ngxenye ithatha indawo yemikhiqizo eyenziwe ngokusika nokufaka i-brazing. Izingxenye ze-MIM zinganciphisa kakhulu izindleko zokukhiqiza kunezingxenye ezikhiqizwa ngokusika.
Izingxenye ZESIBILI ze-MIM: Ukubekezelela okulinganayo komshini wokubumba umjovo izingxenye zensimbi engagqwali zedivayisi yombono wangemuva wasebusuku wesibhamu ngu-0.5%. Impahla yomjovo esetshenziswayo i-thermoplastic binder kanye ne-iron-7% nickel alloy. Ukuminyana komzimba we-sintered kufinyelela ku-7.82 ngesentimitha yesikwele. Izakhiwo zemishini ezicaciswe ezimeni zobuchwepheshe yilezi: amandla aqinile 430MPa, amandla esivuno angama-295MPa, ubulukhuni 55HRC (ngemuva kokungcwatshwa nokucisha), kanye ne-modulus of elasticity 203GPa.
Le ngxenye ekhiqizwa yi- Inqubo yokubumba umjovo wensimbi ye-mimngaphambilini yakhiqizwa ngokusika. Uma kubhekwa isimo esiyinkimbinkimbi sengxenye kanye nezimbobo ezisezindaweni ezihlukene, ukusika kuyabiza. Idivayisi yokubona ebusuku isetshenziselwa isibhamu i-M-6. Ngenxa yokusetshenziswa kwenqubo ye-MIM, intengo yezingxenye ingancishiswa ngo-60%. Ngaphandle kwe-carburizing kanye nokucisha, akukho ukwelashwa okungaphezulu okudingekayo.
Izingxenye zezikhali ezikhiqizwe izingxenye zenqubo yokukhiqiza ye-MIM 2
