Metal Injection Molding

Metal Injection Molding

Since the 1980’s, we have been a leading producer of superfine powders for Metal Injection Molding (MIM). Our expertise and advanced atomization technology enable us to produce very fine MIM powders down to 10µm.

Products and Sizes
Our MIM water atomization technology is compatible with most conventional high-performance stainless steels and alloys. Special size distributions are available as well as some standard sizes.
  • Grades: 17-4PH®, 70/30 Fe/Cr, 430L, 316L, other 300 Stainless Steel series
  • Sizes: Typically smaller than 20µm
Austenitic Stainless Steels

316L used in MIM applications which require good corrosion resistance, strength and ductility. Also available 304L and 310L.

Ferritic Stainless Steels

430L ferritic stainless steel combines good magnetic response and some corrosion resistance. Also available 409L, 410L, and 434L.

17-4 PH® Precipitation Hardening Stainless Steels

17-4PH® grade stainless is used to obtain strength and hardness. It offers better corrosion resistance than 400 series stainless steel. A range of properties and hardness can be achieved through heat treatment. This material is typical in medical applications.

Advantages

Metal Injection Molding (MIM) is a cost-efficient process for manufacturing near net shape small precision parts and complex shaped components in both large and small volumes. Our fine powder is ideally suited to the process and is combined with binders and sintering aids and then sintered into these parts.

Markets

Our MIM powders are used in numerous markets including automotive, industrial, consumer, firearms, medical and IT.
