A hydraulic press consists of two connected cylinders: the first is the smaller of the two, called the plunger or piston, while the second is the larger cylinder, also known as the press frame. Between the two cylinders is a system of pipes filled with a liquid, usually oil or water.
To operate a hydraulic press, force is applied to the plunger, which pushes the liquid through the pipes into the press frame. As the liquid fills this frame, it exerts pressure on the object being pressed inside the frame.
The force generated by a hydraulic press depends on the size of the plunger and the pressure of the liquid. The plunger has a large surface area, which means that even a small amount of force applied to the plunger will create a considerable amount of pressure in the liquid, which is then transmitted to the press frame.
Hydraulic presses are widely used in many different industries, from manufacturing to construction, because they are able to generate a huge amount of force with a relatively small amount of force. They can be used to press metal into shapes, mold materials such as plastics, and even crush cars into small pieces for recycling.
