摘要：
Die filling is the first step in the process of powder compaction. The density distribution depends of the powder characteristics and method of filling. In this work we present the first results obtained with different experimental methods of the filling. Results have been analyzed using a video system which permits the observation of the powder flow. The aim of the work is to determinate the effects of size, morphology and nature of the powder, as well as shoe speed, and die geometry on the apparent density distribution in industrial dies of complex geometry.
