Abstract: Metal plates are placed on opposed surfaces of two heating plates, the metal plates are heated. Then, a hollow plate is placed between the two heating plates, and the two heating plates are moved toward each other. The metal plates, which are heated to a high temperature, are bonded to the outer surfaces of the hollow plate by thermal fusion caused by the heat of the metal plates. After the metal plates are brought into planar contact with the hollow plate, the heating plates are moved away from each other. The heating plates sandwich the hollow plate only for a very short time. Thus, the heat of the heating plates is not transferred excessively to the hollow plate.
