The Research on Discrete Element of Blade Part In Powder Injection Molding

Abstract:

The 3D injection discrete element model of blade injection part is constructed. PFC3D is used to program for filling simulation and analysis. The simulation result shows that there is anisotropy and filling in injection direction first. There is difference between results by discrete element and by Moldflow software. There is large contact stress in reverse direction in sharp angle region and it is filled at last. The injection test result shows that the injection discrete element model is feasible.
