In addition to 30 pages of news from the metal and ceramic injection moulding industry, the 80 page March 2015 issue of Powder Injection Moulding International (Vol.9 No.1) includes the following articles and special features:
Carbon Control: An important discriminant in Metal Injection Moulding
The challenge of carbon control has strongly influenced the development of MIM technology, most obviously in relation to early material selections. Appropriate carbon control is, however, no less important today and it is recognised as one of the fundamental factors influencing final component quality. Prof Randall German, San Diego State University, USA, reviews the history of carbon control in MIM and considers the importance of sintering atmospheres and binder systems, as well as reviewing the relevant reactions that take place during the MIM processing cycle.

GKN Sinter Metals: Process automation enables growth in automotive applications
It has been eight years since PIM International last visited GKN Sinter Metals’ Bad Langensalza Metal Injection Moulding (MIM) plant, one of Europe’s largest MIM operations. Much has happened in the intervening period, with awareness of the technology improving and global MIM sales jumping from around $950 million in 2007 to an estimated $1.5 billion in 2014. Dr Georg Schlieper reports on the development of MIM in Bad Langensalza and the opportunities that lie ahead.

Advances in the Metal Injection Moulding of titanium at Euro PM2014
The Euro PM2014 conference, which took place in Salzburg, Austria, September 21-24, presented an opportunity for the industry to review progress to-date on global developments relating to the Metal Injection Moulding of titanium. Dr Thomas Ebel, from Helmholtz-Zentrum Geesthacht (HZG), Germany, reports on a selection of key presentations from the event, including those with a focus on biomedical and dental applications, Metal Matrix Composites and complex 3D structures.

PIM at Euro PM2014: Magnesium PIM for biomedical applications
A keynote paper at the Euro PM2014 congress presented by Martin Wolff, Helmholtz-Zentrum Geesthacht (HZG), Germany, discussed the viability of processing medical implants from magnesium alloys by Powder Injection Moulding. Magnesium is of particular interest for medical implant applications thanks to, amongst other things, its excellent biodegradability and biocompatibility. Dr David Whittaker reviews the paper for PIM International.

PIM at Euro PM2014: Microstructural studies of advanced PIM materials
In our final report from the Euro PM2014 congress, Salzburg, Austria, September 21-24, Dr David Whittaker reviews two papers which report on microstructural studies of advanced PIM materials. The first paper presents work undertaken on the PIM of metal-ceramic interpenetrating phase composites, whilst the second paper reports on a microstructural evaluation of MIM HK-30 stainless steel, a material with high growth potential thanks to the rapidly increasing use of automotive turbochargers.

Low volume and prototype MIM components using green machining and sinter joining
The rapid production of small quantities of Metal Injection Moulded (MIM) components is of increasing interest to producers worldwide as they look to provide customers with prototypes that offer similar properties to high volume MIM components. In this study Shinya Sakurai and Kazuaki Nishiyabu (Kinki University, Osaka, Japan) and Shigeo Tanaka (Taisei Kogyo Co. Ltd., Osaka, Japan) report on the development of a novel MIM process involving the sinter-joining of components produced by the machining of green MIM compacts. The study focuses in particular on achievable shape and dimensional control.
