Metal Injection Molding

Mastars Metal Injection Molding

Mastars provides a full range of  MIM materials that are useful for a wide variety of applications. Low carbon and high alloy steels for case and through hardening requirements, a full range of austenitic, ferritic, martensitic and precipitation hardening stainless steels, titanium, soft magnetic alloys as well, Co and Ni base super alloys and select non-ferrous alloys. Many of these MIM materials can be heat treated to meet specific mechanical properties for the individual application. Post treatment option such as Hot Isostatic Pressing (HIP) can further enhance mechanical properties for the most demanding applications.
