摘要
The present invention provides a pressure injection molding of magnesium alloy . In the method, cooling the melt of magnesium alloy in the semi-molten state comprising a solid-phase , and cooling the semi-molten state that is also formed of a solid material which is crystallized to a solid phase particulate . That by a solid material in a semi-solid by the injection molding machine presses the mold . Sets the ratio of the primary crystal of the solid material to 55 to 65%. The semi-molten material to the solid to solid-liquid coexistence state to a selected heating temperature , the primary solid phase of size 50 ~ 250 , the solid phase rate in semi-solid form of the 30 to 70% . Maintain the semi-solid state in a mold by injection pressure through the nozzle, the ratio of the main crystal is molded into a metal product in 20 ~ 50%.
