The die-casting process has recently been receiving renewed attention and considerable use as a way to save weight and fabricate unitary combinations of parts. The natural trend is toward increasingly complex product shapes and higher quality requirements. Although die casters attempt to cope with this situation through various types of preliminary analysis, at present, the conditions for the actual die-casting process are set according to the experience of the casting engineer. In this study, die-casting of a test piece was evaluated by Taguchi methods. A single set of conditions, arrived at by raising the S/N ratio, was found to optimize both transferability and density, but repeatability remains a problem for further research.
