MIM Materials
Inoshanda zvinhu zveMetal jekiseni molding
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.
Imhando ipi yezvigadzirwa zvesimbi inokodzera iyo MIM 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.
