Carpenter Powder Products: Stepping up the production of gas atomised powder for the MIM industry
Feature article: PIM International, Vol.5 No.1 March 2011, pages 45-49, 2261 words
Carpenter Powder Products (CPP) is one of the world’s largest and most diversified producers of pre-alloyed gas atomised metal powders.
In the following article, the company outlines its plans to increase its UltraFine® MIM powder producing capacity by around 75% by the end of 2011, positioning itself to meet the just-in-time needs of the MIM industry. The company also shares its view of the MIM industry’s regional development and major markets.
Introduction
Carpenter Powder Products (CPP), a business unit of Carpenter Technology Corp., has for many decades been an important force in the metal powders industry. The business unit produces fine, medium and coarse spherical metal powders in a variety of ferrous and non-ferrous alloys using different melting processes to meet customers’ requirements. This includes fine powders for metal injection moulding.
The story of fine powder production at Carpenter
CPP’s roots date back to the 1960s, well before the development of MIM technology. The earliest incarnation of what is now CPP’s metal powder production story can be traced to the R&D laboratory of Universal-Cyclops’s specialty steel division in Western Pennsylvania, USA. Universal-Cyclops’s powder operation was acquired by Dynamet Inc. in 1991, which itself was subsequently brought into the fold of Carpenter Technology Corp. in 1997.
Carpenter’s first toehold into the MIM powder market came with its 1999 acquisition of the Anval Group, based in Torshalla, Sweden. However CPP’s real push into fine powder technology came with its acquisition of UltraFine Powder Technology Inc. (UFP) in 2008. UFP had been formed in 1986 to commercialise production of gas atomised metal powder. The company’s team of materials and process experts had made significant advances in the production of fine spherical powders suitable for MIM based on technology first developed at the Massachusetts Institute of Technology, USA….
