Hydraulic Presses

The common application of the hydraulic press is straightening, forging, stamping, and forming metal. Besides the heavy-duty tasks above, hydraulic press machines are also suitable for punching, packing, and bending.

A hydraulic press machine is a device that uses hydraulic fluid to generate large amount of force on a small surface area for metal processing. It is typically used in metalworking industries for sheet metal operations such as drawing, deep drawing, punching, blanking.

Hydraulic presses work on the principle of Pascal's law, according to which when force is applied to the confined fluid, the pressure change occurs throughout the entire fluid. In other words, in a hydraulic system, the pressure exerted on a piston produces an equal increase in pressure on another piston in the given system.

Depending on the application type hydraulic presses include arbor presses, laminating presses, pneumatic presses, C-frame presses, and H-frame presses. When choosing the right machine you may consider such factors as pressure, speed, and size. Other options to consider are power and motorized hydraulic presses.

Hydraulic systems are so powerful since they apply confined fluid to a small surface to generate a high amount of force and evenly transmit it across the closed system. Based on Pascal's law, hydraulic presses are able to develop a high intensity of pressure with a relatively small amount of input pressure.

Hydraulic systems operate by using fluid under pressure to transmit force from one location to another. They generally use an incompressible liquid, such as oil, which helps ensure consistent force. The oil is pressured using a pump, and the pressure is transferred to a cylinder or RAM, which then applies the force to the object being pressed or straightened.
