PROBLEM TO BE SOLVED: To provide a sizing die which exhibits high productivity even when a profile molding is molded, prevents the occurrence of nonuniformity and strain in the obtained molding, and is hardly abraded even after repeated molding. SOLUTION: The sizing die 1 is arranged in a post-stage of an extrusion molding mold 2 and cools the molding S extruded from the mold 2 while molding it. A part 11 of the sizing die 1 which correspond to the angular part or the curved part of the molding S is made of a high thermal conductivity material 111 coated with an abrasion resistant material 112.
