Abstract:	Die filling is the first step in the process of powder compaction. The density distribution after die filling on the powder properties and the method of filling. In this work the authors study the effects of powders characteristics, size and morphology, and shoe speed on the type of mass flow during the filling and the resulting density distribution. Experimental results for different powders and die geometries are presented. Three flow regimes have been identified and their influence on apparent density is discussed
