An apparatus and method for forming sheet metal. A head platen having a rubber insert and a lower piston casing which accommodates a piston having an anvil adapted to be aligned with the rubber insert are held together by a lock ring. A hydraulic actuation system comprised of a plurality of pistons mounted on the head platen and the piston mounting the anvil operate to impose a concentrated force to press a workpiece mounted on the anvil into the rubber insert.
