The Wyman-Gordon 50,000-ton forging press. The Heavy Press Program was a Cold War-era program of the United States Air Force to build the largest forging presses and extrusion presses in the world. These machines greatly enhanced the US defense industry's capacity to forge large complex components out of light alloys, such as magnesium and ...
The hydraulic press depends on Pascal's principle.The pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force.
