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 cast- ing 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 experi- mental data used to derive foam pattern resistance parameters for ductile iron, and validate the model.
