MIM (simbi jekiseni molding) maitiro, inova rudzi rutsva rwesimbi chikamu chekugadzira nzira inosanganisa yemazuva ano epurasitiki jekiseni molding process uyeupfu simbi muitiro. Iyi nzira itsva yakaonekwa mukupera kwema1970 uye yainyanya kushandiswa kugadzira zvikamu zvezvombo zvakareruka. Panguva ino ndichasuma akati wandeiMIM simbi jekiseni kuumba zvikamuzvezvombo.
JIEHUANG CHIYANG Yepamusoro simbi jekiseni kuumba kambani:
Chekutanga MIM zvikamu: Electronic kurongedza MIM zvikamu. Ichi chikamu chinoumbwa neMIM (Metal Injection Molding) tekinorojiuye yakaumbwa neF15 giredhi zvikamu (Ni-Co-Fe); kushivirira kwegomba kuri kuwedzera kana kubvisa 0.2mm. Ichi chigadzirwa chesimbi jekiseni chekuumba chinoshandiswa kuOpto-electronic packaging. Chimwe chezvinodiwa ndechekuti kuwedzera kwechigadzirwa kunofanirwa kufanana neiyo yegirazi rakavharwa.
Chinotariswa nemutengi ndechekuyedza mashandiro ekuisa chisimbiso kweMIM yemagetsi enclosure mushure mekunge zvikamu zvave pasi pekuvhunduka kwekupisa. Ichi chikamu chinotsiva zvigadzirwa zvakagadzirwa nekucheka uye brazing. Zvikamu zveMIM zvinogona kuderedza zvakanyanya mutengo wekugadzira pane zvikamu zvinogadzirwa nekucheka.
CHEchipiri MIM zvikamu: Iyo dimensional kushivirira kwejekiseni rekuumba muchina wesimbi isina tsvina zvikamu zvepfuti yekumashure kwehusiku chiratidzo mudziyo i0.5%. Iyo jekiseni inoshandiswa ndeye thermoplastic binder uye iron-7% nickel alloy. Kuwanda kwemuviri we sintered kunosvika 7.82 per square centimeter. Iwo emakanika zvivakwa anotsanangurwa mune tekinoroji mamiriro ndeaya: tensile simba 430MPa, goho simba 295MPa, kuomarara 55HRC (mushure mekuviga uye kudzima), uye modulus ye elasticity 203GPa.
Ichi chikamu chinogadzirwa ne mim simbi jekiseni molding maitiroyakambogadzirwa nekucheka. Mukuona kwechimiro chakaoma chechikamu uye maburi ari munzvimbo dzakasiyana, kucheka kunodhura. Chishandiso chekuona husiku chinoshandiswa pfuti yeM-6. Nekuda kwekushandiswa kweMIM maitiro, mutengo wezvikamu unogona kuderedzwa ne60%. Kunze kwekunge carburizing uye kudzima, hapana kurapwa kwepamusoro kunodiwa.
