Influence of Processing Parameters on the Performances of High Pressure Die Casting Process

This paper presents an approach to determine the influence of processing parameters on the quality of aluminum alloy castings. The casting process considered is a high-pressure casting process used to produce complex shapes in light alloys. The combination of design of experiments and computer-aided casting simulation techniques allow the casting process to be evaluated and help to optimize input process parameters faster. A simulation of casting process, according to the Taguchi method based on L9 orthogonal array, was performed.The output process variables were material shrinkage and cycle time. These values were obtained at the end of the simulation process. Grey relational analysis and analysis of variance were performed. Analysis of variance results show that pressure in the 3rd phase and mould temperature have the most significant influence on the material shrinkage and cycle time.
