Abstract

PURPOSE: To provide a formed article with hole without causing such troubles as damage to dies, plugging-up of the hole in the article, etc. by use of die provided with a hole-making movable piece which is projected from one die face of a press, pressed against the other die face and slides in the pressing direction.
CONSTITUTION: A plastic resin blank P consisting of thermoplastic resin, thermosetting resin, or the like is inserted between an upper die 1 and a lower die 2, and a formed article with a hole 4' is produced while stretching an forming the blank P into a desired shape; this is effected by use of a forming die provided with a hole- making movable piece 6 which is projected from the die face of one die (e.g., the lower die 2), pressed against the die face of the other die and slid in the pressing direction into the inner part of the die 2, being urged toward the die face of said other die. In this case, it is preferable that the blank P is formed in advance with a hole Pa at the predetermined place.
