Patent ID: 7389668

Claim:
A metal molding method for forming a metal body in a predetermined shape with a mold, the mold comprised of a metal body lead-in space, a molding space having a communicating region that communicates with the metal body lead-in space, and a molding region extending from the communicating region, the communicating region being at a proximal end of the molding region, a hole forming pin extending toward the proximal end from a distal end of the molding region, and a cylindrical collar having an inner peripheral surface in sliding contact with the hole forming pin and an outer peripheral surface thereof being in sliding contact with an inner peripheral surface of the mold in the molding region, the method comprising the steps of: inserting the metal body into the metal body lead-in space of the mold; feeding the metal body into the molding space of the mold under a predetermined pressure; and forming the metal body by moving a communicating-region-side end surface of the collar to a distal end side of the molding region along with the feeding of the metal body into the molding region.
