Hydraulic press is a machine that uses liquid as working medium and is made according to Pascal's principle to transfer energy to realize various processes. The hydraulic press is generally composed of the machine (host), power system and hydraulic control system.

There are many types of hydraulic presses (also known as hydraulic presses) that use Pascal's law to make use of hydraulic pressure transmission. Of course, the uses are also diverse according to needs. For example, according to the type of liquid that transmits pressure, there are two categories: hydraulic and hydraulic. The total pressure generated by the hydraulic press is relatively large, and it is often used for forging and stamping. Forging hydraulic press is divided into die forging hydraulic press and free forging hydraulic press. Die forging hydraulic press uses molds, while free forging hydraulic press does not use molds. The first 10,000-ton hydraulic press manufactured in my country is a free forging hydraulic press.
