Mold-Filling Analysis for Ductile Iron Lost Foam Castings

摘要

A mold-filling model for the lost foam casting (LFC) process has been developed for a finite element method (FEM)-based casting simulation software. The model includes the resistance of foam pattern to molten metal flow, and formation of foam pattern degradation-related defects. The principle of this model is described. Experiments were performed to obtain the experimental data used to derive foam pattern resistance parameters for ductile iron, and validate the model.
