PURPOSE: To easily and effectively thermally mold amorphous material.

CONSTITUTION: A powder-like amorphous material is fed from an upper material supply unit 4 to the box 2 of a hollow box state, and hot air is blown from a hot air supply unit 6 to the box 2. Thus, after the amorphous material generates viscosity in the box 2, the box 2 is moved at once to a press 5, the material is delivered, and then molded at once by the press 5. In this manner, the material does not lose its amorphous property, but can be molded in an object shape.
