Abstract
Initial work on compaction modelling assumed that the density of the powder bed in a die at the start of compaction is uniform. This has been challenged from two directions. Firstly, measurements of the density distribution in compacted components did not always agree with predictions and nonuniform fill-density has been used as one explanatory factor [1]. Secondly, recent work on measuring the density distributions of powder beds in filled dies has suggested that variations of the order of 10 % to 15 % in local powder density can be developed [this chapter].
