Improvements in Dimensional Consistency using Starmix™ Bonded Products
PM²TEC 2004, in Chicago, USA. Authors: Daniel Edman, Paul Hofecker, Denis O'Keefe, Ulf Engström, Sigurd Berg. Many factors influence the productivity and efficiency of the powder metal process. Among these are segregation of the mix constituents and filling performance. STARMIX™ products address these issues by bonding ingredients to reduce segregation and increase filling performance. This paper describes the improvements in dimensional stability attainable with STARMIX™ products by using case studies comparing the performance of premixes made with conventional blending to STARMIX™ products. The results of laboratory based testing will also be discussed.
