In usual, the water-soluble lubricants are used in die-casting. But this system has fatal defect, namely, high-energy consumption and environmental problems. Recently, closed die system with use of powder lubricants is widely noticed. The effects of the contents of powder lubricant and die temperature on the quality of casting surface were investigated. The castings had a good correlation between surface glossiness and surface appearance according to the experts in the field of die cast, so surface glossiness was measured as one of the most important surface quality. The quality of casting surface was improved by decreasing the wax content in powder lubricants, because decreasing the wax content improved the glossiness, the flow line, and metal wave, and decreased the surface roughness. A high temperature of die improved the surface glossiness and roughness, because the fluidity was improved. Powder lubricants could provide a surface quality of castings better than conventional water-soluble lubricants.
