The December 2019 issue of Powder Injection Moulding International (Vol. 13 No. 4) has been released and is now available to read for free online or download in pdf format. This issue features 51 pages of industry news, plus the following articles and technical reviews:
Mimecrisa: Pushing the limits of Metal Injection Moulding technology
Mimecrisa, the Metal Injection Moulding business of Spain’s Ecrimesa Group, based in the northern city of Santander, is one of Europe’s leading MIM manufacturers, with more than twenty-five years’ experience in the technology.
The company, which was the world’s first MIM manufacturer to install a continuous sintering furnace for MIM part production, continues to go from strength-to-strength, with a reputation in particular for the production of parts that push the size limits of the technology.
Georg Schlieper recently visited the company on behalf of PIM International and reports on the history and current status of the company.
PMTi2019: International conference on the PM and AM of titanium highlights a bright future for sinter-based technologies
The PM Titanium conference series, previously held in Brisbane, Australia (2011), Hamilton, New Zealand (2013), Lüneburg, Germany (2015) and Xi’an, China (2017), is a key international event for those involved in the powder metallurgical processing of titanium and its alloys. In September the event reached its fourth continent, North America, being held at the University of Utah, Salt Lake City.
In this article, Dr Thomas Ebel reviews a selection of conference presentations that suggest that progress on the sinter-based processing of titanium and titanium alloys continues to mature, with cost reduction high on the agenda.
Euro PM2019: Special Interest Seminar outlines competing and complementary aspects of MIM and sinter-based AM
During Euro PM2019 in Maastricht, the Netherlands, October 13–16, 2019, a Special Interest Seminar on MIM and sinter-based AM was held with the purpose of generating a better understanding of the competitive and complementary aspects of these technologies.
Dr David Whittaker reports for PIM International, on three presentations given by Desktop Metal’s Dr Animesh Bose, GKN Sinter Metals’ Dr Simon Höges and Fraunhofer IFAM’s Dr Thomas Hartwig, on the areas in which sinter-based AM poses a threat to MIM, and those areas in which it can provide new opportunities, were considered.
The MIM of Nimonic 90 for a new generation of turbocharger components
Nimonic 90, a trademarked superalloy produced by Special Metals Corporation, is designed specifically for high-temperature applications. Primarily, it is used in turbine blades, discs, ring sections, and forging and hot working tools.
When processed by MIM, Nimonic 90 has the potential for superior mechanical properties which could pave the way for the use of Metal Injection Moulding in new automotive applications such as turbocharger compressor wheels.
In this article, Boon Sing Ng, Alvin Wei Yang Lim and Chee Hoo Liang, from Singapore’s AMT Pte Ltd, look at the material’s economic and functional viability, when compared to conventional alloys such as aluminium, as the material for the next generation of high-performance MIM applications.
