Back to basics: Sintering and furnace technology for metal injection moulding
Sintering is the binding together of metal or alloy powder particles when heated to high temperatures. As will become clear in this latest feature article in our ‘back-to-basics’ series by Dr. Georg Schlieper, it is also the most complicated aspect of metal injection molding, requiring a detailed understanding of sintering practice and the furnaces used.

Sandvik Osprey: A leader in the production of gas atomised powders for MIM
Sandvik Osprey’s powders are well known in the metal injection moulding (MIM) industry and the fine spherical powders that are produced by the company’s proprietary gas atomisation technology have made a significant contribution to MIM’s penetration of new markets. Nick Williams, Editor of Powder Injection Moulding International, reports on a visit to the company’s powder production facility in Neath, South Wales. View full preview

Germany’s MIM Master: The development of continuous sintering furnaces at Cremer
Cremer Thermoprozessanlagen GmbH, Düren, Germany is a leading furnace supplier to the powder metallurgy industry and market leader in continuous debinding and sintering furnaces for metal injection moulding. Dr. Georg Schlieper visited the manufacturing plant for Powder Injection Moulding International in early 2009 and spoke with Ingo Cremer, General Manager, about the company’s history, current situation and future outlook.

TECHNICAL PAPERS

Sintered Ba hexaferrite shaped by powder injection moulding in a DC magnetic field
B. S. Zlatkov, M. V. Nikolic, H. Danninger, O. Aleksic
Ba – hexaferrite specimens with an oriented structure were produced by the powder injection moulding technology (PIM). Ferrite powder (BaFe12O19) with an average particle size of 0.4 µm was mixed with a low viscosity binder (wax, thermo-plastics, solvents and additives) to form a feedstock to be used in the PIM process. The feedstock was injected into a cylindrical mould by an injection moulding machine. View full preview

Co-sintering of functionally graded Fe2Ni/Fe2NixCr composites
Hao He, Yimin Li, Jia Lou, Jianguang Zhang
In this work, the co-sintering compatibility between Fe2Ni and Fe2Ni with different amounts of Cr additions (Fe2NixCr, x=0.5, 1, 3) was studied. The intent is to manufacture functionally graded composites for applications that require a combination of toughness and wear resistance. The densification, bond strength and microstructure of the composites were examined…… View full preview

Advanced metal powder injection moulding for multilayered micro porous titanium components
Kazuaki Nishiyabu, Satoru Matsuzaki, Shigeo Tanaka
Metal powder injection moulding (MIM) is a promising net-shape manufacturing method for porous metal components with high dimensional accuracy and 3 dimensional complicated shapes, which are required in several highly functional applications. Powder space holder (PSH) method is capable of fabricating the controlled pore structures…… View full preview
