Abstract

PURPOSE: To prevent the surface of a base material of a metal-covered plate from being exposed, by using a punch having a punch diameter greater than the diameter of a punching hole of a die so that the surface of the base material defining the hole may be covered with the portion of the metal which is around the hole.
