Abstract

Recent increasing demand for high quality castings, diecasting technology development starting from the conventional diecasting is progressing to the squeeze casting and further to the Rheo-casting. The casting quality basically depends on the flow characteristics and the solidification phenomena in the cavity. As for the Rheo-casting, those characteristics or phenomena differ significantly from the others because of its less liquid phase. In this research, the real Rheo-casting using a practical mold is carried out, then the flow analysis by AdStefan is done to compare the results between them. The result of flow analysis shows that it is applicable to the practical purpose. The fluidity performance of a thin and large product of Rheo-casting is discussed. The effect of Rheo-casting on shrinkage defect is also discussed comparing the phenomena with the conventional diecasting.
