Press tools are commonly used in hydraulic, pneumatic, and mechanical presses to produce the sheet metal components in large volumes. Generally press tools are categorized by the types of operation performed using the tool, such as blanking, piercing , bending , forming , forging , trimming etc.
The maximum mechanical advantage possible for a hydraulic jack is not limited by the limitations on screw jacks and can be far greater. After World War II, improvements to the grinding of hydraulic rams and the use of O ring seals reduced the price of low-cost hydraulic jacks and they became widespread for use with domestic cars. Screw jacks ...

A forming press, commonly shortened to press, is a machine tool that changes the shape of a work-piece by the application of pressure. [1] The operator of a forming press is known as a press-tool setter, often shortened to tool-setter. Presses can be classified according to their mechanism: hydraulic, mechanical, pneumatic;
The working principle of a hydraulic jack. In 1838 William Joseph Curtis filed a British patent for a hydraulic jack. [4] 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]
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.
