Optimization of the process parameters effective on the product quality in die casting of magnesium alloys

Magnesium alloys have been used and preferred in many sectors, especially in automotive, aerospace and electronic industries with its appropriate characteristics like lightness and strength. High-pressure die casting of magnesium alloys has been the fastest grown up and the most globally developed section in magnesium industry. Although high-pressure die casting is a very precision process; there are many effective factors on the product quality and mechanical properties. These factors consist of the casting product design and die construction and the various process parameters. Wrong selection of the process parameters for the casting operation can cause defective and low mechanical property casting products even they have perfect design features. Therefore, the process parameters are the most important factors that are effective on the product quality. For the better mechanical properties, low porosity content and perfect features; the optimum process parameters should be determined. The process parameters are casting and die temperatures, filling time of the die, plunger and gate velocities, injection and intensification pressures with protective gas mixing rate. In this study, most effectives of them were gathered and analyzed in detailed manner of the quality and casting defects.
