Should we need to define the press; it is a metal forming machine tool. They are designed to form or cut metal by applying mechanical force or pressure. With their help, you can form metal in any desired shape without removal of chips. Moreover, the presses are exclusively intended for mass production work and their key advantage of using presses, is that they are the fastest and most efficient way to form any sheet metal into the finished product. Press machine tools have two main types, hydraulic presses and mechanical presses. We should know that the selection of a type of machine press depends on the factors of the manufacturing process.

At this point, selection of a type of machine press depends on the factors of the manufacturing process. The first consideration would be the basic type of process the press tool will be employed to perform. As an example, a press for metal forging, a press for extrusion, a press for impact extrusion, or a press for sheet metal working will all have different general requirements. The next key factor in machine press selection for a manufacturing operation is the press capacity required. Required press capacity is likely related to the size of the work stock, and type of process. Length of stroke over which the press delivers force is another primary factor when choosing a press machine tool, this also will be related to the basic type of process being employed.

By definition, the mechanical press transforms the rotational force of a motor into a translational force vector that performs the pressing action. Therefore, the energy in a mechanical press comes from the motor.

Mechanical presses are generally faster than hydraulic or screw presses, (actually the screw press may also be classified as a mechanical press). Unlike some presses, in a mechanical press, the application of force varies in both speed and magnitude throughout the distance of the stroke.

Secondly, hydraulic presses are a powerful class of machine tools, they derive the energy they deliver through hydraulic pressure. Fluid pressure, in a particular chamber, can be increased or decreased by the use of pumps, and valves. Hydraulic presses are a powerful class of machine tools, they derive the energy they deliver through hydraulic pressure. Fluid pressure, in a particular chamber, can be increased or decreased by the use of pumps, and valves. This involves longer contact with the work, therefore the cooling of the work can be an issue when hot forming a part with hydraulic force. Hydraulic presses are capable of being the most powerful class of presses.
