Hydraulic press machine are commonly used for forging, clinching, moulding, blanking, punching, deep drawing, and metal forming operations. 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 machine work in the following steps:

1.This is based on Pascal’s law, Pascal’s law state that the intensity of pressure in a static fluid is transmitted equally in all the direction.
2.The hydraulic press consists of two cylinders of different diameters. One of the cylinders is of large diameter and contains a Ram, while the other cylinder is the small diameter and contains the plunger as shown in the below figure.
3.The two cylinders are connected by a pipe.
4.The cylinders and pipe contain a liquid through which pressure is transmitted.
5. When a small force f is applied on the plunger in the downward direction, a pressure is produced on the liquid in contact with the plunger.
6.This pressure is transmitted equally in all directions and acts on the RAM in the upward direction as shown in the figure.
7.The heavier weight placed on the ram is then lifted up.
