PROBLEM TO BE SOLVED: To provide excellent mechanical properties and a fine metal structure without a shrinkage cavity, which can not be obtained only by a semi-solidified casting method or a semi-solidified forging method (the molding in a semi-solidified state but not the molding in a solid state), by continuously executing the pressurization molding in a state that the solid phase rate is 100 % after a semi-solidified metal is subjected to the pressurization molding without applying a complicated method. SOLUTION: The semi-solidified metal supplied into a die cavity part is subjected to the pressurization molding with a pair of the upper/lower pressurization molding dies. The upper/lower pressurization molding dies have nearly the same area as the projected area of the upper face or the lower face of a molded product. A second die, which vertically moves in an insertion hole bored in the vertical axis direction, is provided to at least either the upper die or the lower die. COPYRIGHT: (C)2005,JPO&NCIPI
