An orthogonal experiment with fouir factors and three levels (Lq,3^4) was used to evaluate the effect of various die-casting processing parameters on the quality and mechanical properties of an A791D magnesium alloy cylinder head cover component. The results show that the injection speed and casting and die temperatures all influence the component quality, with the influence of the casting pressure being the smallest. The injection speed and casting pressure are the two most important factors influencing the tensile strength. The best die-casting parameters for the magnesium alloy cylinder head cover component were determined to be a casting temperature of 660℃, a die temperature of 200℃, an injection speed of 70 m · s^-1, and a casting pressure of 65 MPa. The porosity is one of the most important parameters influencing the casting strength.
