Abstract
A metal material is placed on a lower mold of a press metal mold which has an upper mold and the lower mold not having engagement portions. The metal material is fused by a high energy heat source, and obtained molten metal over a melting point is pressed with the press metal mold and transformed into a predetermined configuration. The molten metal is cooled at a rate over a critical cooling rate simultaneously with or after the transformation, and the molded product of amorphous metal in predetermined configuration is obtained.

A method for manufacturing a molded product of amorphous metal comprising the steps of:
- placing a metal material on a lower mold of a press metal mold having an upper mold having a smooth concave curved face and the lower mold having a cavity without engagement portions fitting each other;
- fusing the metal material by a high energy heat source to produce a fused molten metal material therein;
- transforming the fused molten metal material over a melting point into a predetermined configuration by pressing it between the upper mold and the lower mold;
- and
- cooling the molten metal material at over a critical cooling rate simultaneously with or after the transformation to produce the molded product of amorphous metal in the predetermined configuration wherein a gap having a thickness dimension of 0.1 mm to 3.0 mm and a width dimension of 4.0 mm to 20.0 mm is formed on the upper mold or the lower mold along a portion of a parting line therebetween into which excessive molten metal material flows in the molding process.
