Hydraulic press-A hydraulic press is a device (see machine press) using a
hydraulic cylinder to generate a compressive force.
The hydraulic press depends on Pascal's principle-the pressure throughout
a closed system is constant.
Joseph Bramah invented the hydraulic press, hence it is also known as the
Hydraulic presses are commonly used for forging, clinching, moulding,
blanking, punching, deep drawing, and metal forming operations.
The concept of the hydraulic press is based on Pascal's
theory, which states that when pressure is applied on fluids
in an enclosed system, the pressure throughout the
system always remains constant. In simple words, a
hydraulic press is a machine that makes use of the
pressure exerted on the fluids to crush something.
How the Hydraulic Press works
Since the hydraulic press works on the basis of Pascal's Law. A
hydraulic press consists of basic components used in a hydraulic
system that includes the cylinder, pistons, the hydraulic pipes, etc.
Uses Of A Hydraulic Press. A hydraulic press is used for almost all
industrial purposes. But basically it is used for transforming metallic
objects into sheets of metal. In other industries, it is used for the
thinning of glass, making powders and make break heavy parts.
As of today, hydraulic presses are available in both the
categories, i.e., automatic and manually operated. In
case of manually operated hydraulic presses, many safety
measures have to be taken such as using interlocking and
