ABSTRACT:
One method of forming a workpiece made of thermoformable material includes the steps of: (a) supporting a raw workpiece on a suspension tray; (b) moving a pair of relatively hot forming dies into position above the workpiece; (c) closing the hot forming dies against the workpiece to heat the workpiece and to form and shape the workpiece into the desired configuration; (d) opening the hot forming dies and removing the hot forming dies away from the workpiece; (e) moving a pair of relatively cold forming dies into position above and below the workpiece; (f) closing the cold forming dies against the workpiece to cool the workpiece while maintaining the workpiece in the desired configuration; and, (g) opening the cold forming dies and removing the finished workpiece form the suspension tray. Other methods are also disclosed.
