Magnesium alloy forming technology is a hot spot in the world. This paper introduces the application of AM60B magnesium alloy and die casting technology in the forming of motorcycle wheel casting, and the test and analysis of die casting process, Finally, qualified magnesium alloy wheel castings are produced. the selection of die casting process parameters was 680 ∼ 700°C, the casting temperature of 240 ∼ 280°C, and the pressure ratio between 180 ∼ 200MPa and the holding time was 20 ∼ 25s. Under the condition of optimum technological parameters, obtained by casting the mechanical properties testing results: σ b =218∼227MPa, HBS=66∼71, δ 5 =9.8 ∼10.7% and a k = 17.5 * 10 4 ∼18.7 * 10 4 j / m 2 . The practice has proved that the die casting technology is a suitable process for magnesium alloy wheels, and it has reference value for the mass production of large area magnesium alloy casting.
