This article describes the simulation of different powder technological processing steps. Among many routes the die compaction processing route is selcted as a demonstration example. From the process chain of die compaction the powder conditioning, pouring of the loose powder into the die, powder compaction, sintering, postsintering mechanical densification, and service behavior are all included. Examples are given and some limitations are discussed for each individual step after a very short description of the state of the art.
