| Abstract: | The FEM numerical simulation to imitate the cold isostatic pressing process of powder metallurgical component is introduced and the technical problem fully discussed and flow of the powder and distribution of the density analyzed with the aid of FEM software. It is shown that the geometrical demension of P/M component and shape of mandril have great in fluence on the consolidation of the P/M component. Improvement measures are proposed to prolong the service life of the component. |
