[0002] A four-column hydraulic press is a mechanical equipment that uses the static pressure of hydraulic oil delivered by an oil pump to process metal, plastic, rubber, wood, powder and other products. A four-column hydraulic press, also known as an oil press, is a machine that uses liquid pressure transmission based on Pascal's law. There are many types. The uses are also diverse according to needs. For example, according to the type of liquid that transmits pressure, there are two major categories: oil press and water press. The total pressure generated by the water press is relatively large and is often used for forging and stamping. Forging hydraulic presses are divided into die forging hydraulic presses and free forging hydraulic presses.
