Abstract
An apparatus for consolidating a workpiece includes an oven having a heating cavity and a consolidation press received within the heating cavity of the oven. The consolidation press includes a base, a pressure platen disposed in facing relation to the base, and an expandable bellows operatively connected to the pressure platen to force the pressure platen toward the base. The bellows is expanded by a gas pressure supplied by a pneumatic source. In operation, a workpiece is placed between the base and the platen, and a force is applied to the workpiece by operation of the bellows.
