MIM - metal powder injection moulding offers a wide range of design possibilities. A major advantage of this process is that components with demanding geometries, which can only be produced in multiple parts using conventional methods, can be manufactured in a single piece.

 

available materials:

Steel - Titanium - Cu alloys - Silver - Gold

Typical component sizes:
- Weight from 1.0 gr to approx. 100 gr / heavier parts also possible
Sizes: 5 mm - ca 100 mm
Quantities: starting from 1000 pcs per lot
