Study on Numerical Simulation of Mold Filling and Solidification Processes Under Workstation Environment

Mold filling and solidification process simulation plays an important role in optimizing the risering and gating design,in minimizing the trial production period, in reducing the manufacturing cost and in assuring the soundness and the quality of castings. Therefore,it becomes one of the hottest topics at the research frontier in foundry technology. Practical 3-D computer numerical simulation system for temperature distribution during solidification as well as shrinkage cavity and porosity prediction has already been put into application. Great progress has been made in fundamental research on mold filling, thermal stress and micro-structure as well as in practical approaches of numerical simulation.
