Inoshanda zvinhu zveMetal jekiseni kuumba:
Miitiro yeMIM inoshandiswa kune zvakasiyana-siyana zvezvinhu, zvinosanganisira yakaderera alloy simbi, Stainless simbi, tool simbi, nickel base alloy, tungsten alloy, hard alloy, titanium alloy, magnetic materials, Kovar alloy, fine ceramics, etc.
Ndeupi rudzi rwezvigadzirwa zvesimbi zvakakodzera kuneMIM maitiro:
1. MIM components uremu kazhinji 0.2g - 200g.
2. Nzvimbo yakarongwa i100 square centimeters.
3. Iyo miM yezvikamu saizi yakarurama pamusoro pe10MM ndeye ± 0.5%.
4. Zvikamu zveMIM zvakanyanya kukora kwemadziro ndeye 10MM.
5. Minimum saizi 0.2MM.
