Abstract

Abstract:

The filling process of non Newtonian fluid flow in an injection mold was investigated and numericaly simulated. The quasi steady flow field governed by a nonlinear elliptic equation was computed with a finite element method, and the unsteady transport equation of temperature was solved by a mixed finite element finite difference method. For the simulation of melt front advancing, a formulation based on the method of flow analysis network was adopted, which has the advantage of being amenable to automatic algorithm. Examples of computation were given and the results discussed.

Key words: injection mold, filling process of an injection mold, CAD, non Newtonian fluid flow
