Metal Injection Moulding: Celebrating forty years of innovation
Forty years ago, in 1979, Metal Injection Moulding arrived on the global stage thanks to two groundbreaking award-winning components from the technology’s pioneer, Parmatech Corp. Since then, the industry has gone from strength-to-strength, with MIM parts used in a highly diverse range of applications that we all rely on – often unknowingly – on a daily basis.
These range from automotive, watch, smartphone and consumer electronics applications, to firearms, cutting tools, precision surgical devices and high-temperature jet engine components. PIM International’s Nick Williams reports on the industry’s evolution and highlights a number of ‘milestone’ applications.

Metal Injection Moulding: An alternative manufacturing process for aerospace applications?
The aerospace sector has long been recognised as an important potential market for the Metal Injection Moulding industry. However, extended application development cycles, combined with a lack of fundamental process understanding and rigorous validation requirements have, until now, held back the technology.
In the following article, Rolls-Royce’s Enrico Daenicke and Schunk Sintermetalltechnik GmbH’s Ingolf Langer report on the development of a new generation of high-performance MIM components that are now flying in Rolls-Royce aero engines: IN713LC superalloy stator vanes.

Successful high-volume part production with HP Metal Jet 3D Printing: A guide for MIM professionals
While commercial plastic Additive Manufacturing has been a reality for nearly thirty years, metal Additive Manufacturing is largely still in its infancy despite the technology existing for nearly two decades. This is due to the difficulty of using metal Additive Manufacturing to produce cost-effective parts to the high quality and high volumes necessary to make it attractive for broader applications.
With its Metal Jet system, HP Inc. hopes to change this, making the technology accessible to industry. In this article, HP’s Uday Yadati explains how the Metal Jet system can bring further success for MIM producers.

The effect of sintering conditions on magnetic and phase characteristics of X15 CrMnMoN 17-11-3 MIM
nickel-free stainless steel
There is a growing market demand for non-magnetic stainless steel components, in particular from the consumer electronics industry, that can be processed by Metal Injection Moulding. The stainless steel alloy X15 CrMnMoN 17-11-3 (also known as P.A.N.A.C.E.A. by users of BASF SE’s Catamold®) is one widely known option; however, when using this material, abnormal ferromagnetism can occur as a result of improper sintering profile design.
Here, Dr Shin Lee and Shu-Hsu Hsieh, Chenming Mold Ind. Corp. (UNEEC), Taiwan, consider the root cause for this correlation between sintering parameters and final abnormal magnetic property.
