| Abstract: | A systemic research of FEM numerical simulation to imitate the CIP process of powder materials is introduced. The flow of the powder and the distribution of the density are analyzed with the aid of the FEM software MARC. It is shown that the geometry figure of the powder product and shape of mandril have great influence on the consolidation of powder product. And the improvement measures are proposed. So the FEM numerical simulation is an effective method to determine final ideal shape of die. And the manufacture efficiency is improved, and the service life of powder product is prolonged. |
