Abstract

PURPOSE:To improve eroding resistance and to prevent breakage of a tip by making sliding face of ceramic in the tip with a sleeve and having heat expansion evading structure to radius direction of the tip in the plunger tip for die casting. CONSTITUTION:The sliding face of the plunger tip 11 with the sleeve is made of the ceramic of silicon nitride or sialon, etc., and gap (b) is formed between periphery of a rod 13 and inner face of the tip 11 to absorb the heat expansion of the rod 13 in the gap (b). By this method, the wear resistance and eroding resistance can be improved and the breakage of the tip can be prevented.
