Production of high density PM automotive components utilizing advanced warm die compaction technology

摘要

High density compaction techniques (warm die compaction) has broadened the potential application base for PM components. Because single press - single sinter (1P1S) compaction can now achieve densities in excess of 7.3 g/cm3; this cost effective part production approach is often the preferred methodology for new high density automotive applications. A key initiative in achieving higher part densities is the advance in lubricants and premix-ing technology enabling reductions in the amount of lubricant required to as little as 0.25% by weight of the premix.
