A high energy rate metal forming concept is described that uses energy from a high velocity free piston impacting on a liquid. The piston is driven by compressed air. The characteristics of the energy transfer and the pressure buildup are analyzed for a limiting case. A basic typical system design is presented. Schematic diagrams and curves illustrating limiting pressure rise and other characteristics of a typical system are presented.
