Pressform und Herstellmethode derselben

摘要

A press molding die which has a concave portion (5), that has a shape corresponding to a punch (3), on a molding surface of a molding die (1), and which presses a workpiece (4) placed on the molding surface into shapes by pressing a part of the workpiece (4) while pressing the workpiece (4) using a pad (2) on the periphery of the concave portion (5), characterized in that a micro-rough layer (6) is formed by performing a particulate coating process on at least one of a portion of the pad (2), for pressing the workpiece (4), and a portion of the molding surface of the molding die (1), corresponding to the portion of the pad (2). Preferably, the height of roughness of the micro-rough layer (6) is 0.01 to 0.06 mm, and the particulate coating process is performed using a silicofluoric chrome plating solution.
