Indo-MIM: Exploring the dividing line between Metal Injection Moulding and Binder Jetting

There can be few Metal Injection Moulding companies which are not keeping one eye on metal Binder Jetting (BJT). This rapidly progressing Additive Manufacturing process offers the promise of tool-free, high-volume production that can leverage much of an existing MIM producer’s expertise and equipment. Indo-MIM Inc., one of the world’s largest MIM producers, with operations in India and the US, started its exploration of Binder Jetting in 2019.

Here, the company’s Jag Holla shares his insight into what the company has learnt so far, and where he sees the dividing line between MIM and BJT.

In MIM we trust: Integrating optical fingerprinting in Metal Injection Moulded products

Metal Injection Moulding is a technology that, in addition to its industrial application, is widely used for the manufacture of luxury goods, from watch cases to the decorative logos for exclusive handbags. For many such applications, the value of technologies for counterfeit prevention, quality control or identification for recycling purposes is very high.

Erik Dietrich, Applied Research Engineer at Demcon Metal Injection Moulding, Enschede, the Netherlands, reports on an innovative solution developed with Germany’s Tailorlux GmbH that enables the integration of unique optical fingerprint technology into MIM feedstocks.

Beyond Ceramic Injection Moulding: The potential of Binder Jetting for complex ceramic structures

The combination of generative and algorithmic design with Additive Manufacturing is opening up a new world of opportunity for ceramics. Whilst Ceramic Injection Moulding (CIM) has, until now, been the manufacturing process that offered the greatest level of design freedom for industrial production, ceramic AM now brings a level of freedom to produce complex structures that go far beyond what can be moulded.

Prof Alberto Ortona, from the Hybrid Materials Laboratory at University of Applied Sciences and Arts of Southern Switzerland (SUPSI), explores ceramic Binder Jetting, the opportunities that it presents, and its current limitations.

High-nitrogen, nickel-free austenitic stainless steel for Metal Injection Moulding

The ability of Metal Injection Moulding to efficiently manufacture complex stainless steel components to net shape has enabled it to become a go-to technology for sectors such as watchmaking, luxury goods and medical devices. However, the challenge of meeting the growing demand for nickel-free stainless steels presents a number of challenges for MIM producers.

In this article, Pierre Girin and Jean-Claude Bihr, from France’s Alliance MIM, review these challenges and share insight into the processing of a material class that holds great promise for the industry.

The sustainability of Metal Injection Moulding: from powder to feedstock and finished parts

A Special Interest Seminar in the programme of the virtual Euro PM2021 conference, organised by the European Powder Metallurgy Association (EPMA) and held October 18-22, 2021, focused on developments aimed at enhancing the sustainability of production by Metal Injection Moulding (MIM).

This seminar comprised three presentations from representatives of different points in the MIM process chain.
