Magnesium alloy is a light weight metallic which offers good engineering properties and environmental advantages. Most cast components in this material are produced y the traditional casting processes, predominantly the die-casting process. The Expendable Pattern Casting Process (EPC process) is a relatively new casting process which provides many design, processing and environmental benefits. However, the process differs significantly from the conventional empty mould sand casting process and there is the need for research to develop an understanding of the process parameters.
