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.
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 ...

It was built as part of the Heavy Press Program by the United States Air Force. It was manufactured by Mesta Machinery of West Homestead, Pennsylvania, and began operation on May 5, 1955 ...
Some press brakes have CNC controls and can form parts with accuracy to a fraction of a millimeter. Bending forces can range up to 3,000 tons. [2] [3] [4] A punch press is used to form holes. A screw press is also known as a fly press. A stamping press is a machine press used to shape or cut metal by deforming it with a die. It generally ...
In 1851, inventor Richard Dudgeon was granted a patent for a "portable hydraulic press" – the hydraulic jack, a jack which proved to be vastly superior to the screw jacks in use at the time. [5] Hydraulic jacks are typically used for shop work, rather than as an emergency jack to be carried with the vehicle.
From 1985 onwards, all new machines carried the 'RB' name instead of 'Ruston-Bucyrus', and in 1987, a new mechanical/hydraulic powered 51–60 model developed from the 38-RB was offered for use as a crane or dragline excavator [1] In 1990, RB bought from its rival Priestman, the design and manufacturing rights to Priestman's Variable ...
