A pressure molding method and apparatus uses a mold with a casting cavity and a pouring gate through which a molten metal is fed into the casting cavity. After feeding a molten metal into the mold through the pouring gate to fill the casting cavity and pouring gate, a cap member is placed on the mold to bring its open end into contact with a dead head of the molten metal in the pouring gate of the mold so as to form an air-tightly sealed chamber between the cap member and dead head of the molten metal. Pressure is supplied into the sealed chamber to force the molten metal in the mold through the dead head.
