Abstract
For the Thixomolding of magnesium alloys, process technology has not been developed so far. In this study, investigation of the relationship between the molding conditions and the defects was performed using "Design of experiment". The variable factors in those molding conditions are die temperature, magnesium slurry injection temperature, and injection speed. Die temperature has some influence on the fluidity of magnesium slurry, even up to the limit of die temperature. Magnesium slurry temperature is preferred to be at a high temperature for the fluidity of magnesium slurry. For the injection speed, the fluidity was optimized at a higher injection speed. When the die cavity thickness became smaller, a gap between designed thickness and stock thickness of molded part increased.
