Flow of Finite Element Analysis of Metal Powder in Medal Injection Mold Runner
Based on the continuum theory, combined with the characteristics of metal injection molding, constructs assumptions and control equation in the die filling process of MIM.With the FLOTRAN hydro-analysis module of ANSYS software, the melt’s velocity ,temperature and pressure fields during injection molding were simulated and compared for different sizes of circular section runners,and discussed the influences between different diameter runners and injection pressure on the flow behavior of melt. The simulation provided theoretical guidance for the design and selection of mold runner in the production.
