Hydraulic press is a machine based on pascal's law which is used for pressing or compressing purpose.
It uses are :
- For pressing plywood, cardboard, and hay
- for squeezing oil out of seeds at the oil mills.
- In iron factories making railway coach and wheels.
- for pressing book cotton goods etc.
Hydraulic presses 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.In summary, mechanical presses are still the fastest, but they lack flexibility. Hydraulic machines allow more versatility in drawing and forming of complex parts but they're slow. A servo press has many of the best characteristics of both.On most presses, the maximum pressure will be no more than 200 bar or 3,000 psi.

A hydraulic press works on the principle of Pascal's law, which states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid. Within the hydraulic press, there is a piston that works as a pump, that provides a modest mechanical force to a small area of the sample.
A hydraulic press has all of the essential components of a basic hydraulic system. It has a set of cylinders, punches (or pistons), hydraulic pipes that move the fluid, and a die (or anvil). The pistons use liquid under pressure to push on the anvil with a high level of force.Three common varieties of hydraulic fluids found on the market today are petroleum-based, water-based and synthetics. Petroleum-based or mineral-based fluids are the most widely used fluids today.Hydraulic Actuators are ideal for pressing applications where high force, speed and precision control of position speed and force are required. Press applications include: Metal forming presses learn more.
