Vacuum die casting for magnesium alloy motorcycle wheel was analyzed.The results indicate that high pressure die casting with vacuum can decrease or eliminate oxidized inclusion and gas hole occurred in conventional die casting wheel

greatly improving quality of the wheel

meanwhile

the mechanical properties of the vacuum die casting wheel can be improved by heat treatment.Bottom-pouring with vacuum-drawing at the heart for magnesium alloy wheel can eliminate the shortcoming of heartpouring with vacuum drawing at the top.In addition

compared with single feeding-pressure in heartpouring with vacuum-drawing at the top

double feeding-pressure for wheel edge and wheel heart can greatly improve the mechanical properties of the wheel

decreasing the materials cost due to the thickness-increment for wheel spoke and wheel heat in heart-pouring with vacuum-drawing at the top.
