Only small-diameter tubing (which more easily resists pressure) is needed if the pump is separated from the press cylinder. Hydraulic presses are commonly used for forging, clinching, molding, blanking, punching, deep drawing, and metal forming operations. Hydraulic presses are also used for stretch forming, rubber pad forming, and powder compacting.The hydraulic press is advantageous in manufacturing, it gives the ability to create more intricate shapes and can be economical with materials A hydraulic press will take up less space compared to a mechanical press of the same capability. 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.
