Abstract

The filling and solidification process of A356 alloy by semi-solid squeezing casting was simulated by the Anycasting software.Effects of the injection speed and pouring temperature on squeezing casting process were investigated.Through analyzing defects

the processing parameters and the mould were optimized.The results show that high-quality castings can be produced with the mould preheating temperature of 200 ℃

the pouring temperature of 600 ℃

the injection speed of 0.5 m/s and ingate thickness of 5mm.
