Deep Draw Hydraulic Press
Deep Drawing Hydraulic Press is a machine which makes sheets of metal by a mechanical action of a punch by a hydraulic cylinder to generate a compressive force which makes blank sheets of metal. It is a materiel retention by a shape transformation process. The Hydraulic press pressures throughout a closed system constantly depending on Pascal's principle which is “pressure on a confined fluid is transmitted undiminished and acts with equal force on equal areas and at 90 degrees to the container wall.” The piston acts as a pump which is one part of the system that, with a modest mechanical force acts on a small cross sectioned area. There is another part of the machine which is a slightly larger piston that generates a large corresponding mechanical force.
