Mechanical Press

What is a Mechanical Press?

A mechanical press is a machine press that is primarily used for forming sheet metal and metal extrusion. The mechanical press is not only used for sheet metals but also used for manufacturing plastic products and a variety of machining operations such as broaching. Machine press requires a great amount of output force to complete the metalwork, for example, to deform a considerable piece of metal. The type of energy source, the manner, and nature where the machine press will transfer the energy vary, defining the efficiency as well as the output the machine tool can provide.

How Does Mechanical Press Work?

In short, the working principle of the mechanical press is to convert the rotational force from the electric motor to a translational force which drives the mechanism of pressing work. The energy source of the mechanical press machine is typically a motor. Using a mechanical press machine, there are 3 main steps to complete the metal forming process. The production cycle begins with the material placed on the dies where the metal sheet or other raw materials should stay in place for machining. The operators should then manipulate the mechanical press to apply appropriate pressure in order to force and shape or alter the raw materials as they need. Subsequently, the finished products will be ejected and collected from the mechanical machines. All components in a mechanical press require to be lubricated through the internal system, in general, which supplies a stable flow of lubricants to ensure smooth movement during the pressing process.
