MIM Sintered Watch Case Bezel Component

Product Presentation

This watch case bezel component is manufactured by metal injection molding, enabling intricate bezel profiles, dial-seating steps and fine surface detail to be reproduced in high volume. MIM provides excellent surface finish and dimensional consistency that would be difficult and costly to achieve by machining alone.
