What is hydraulic press?

A hydraulic press is a machine that uses a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever, and is also known as a Bramah press after the inventor, Joseph Bramah, of England. It is commonly used for metal forming, forging, molding, blanking, and powder compacting. It works on the principle that pressure applied to a confined fluid is transmitted equally in all directions; therefore, a small force applied to a small area can create a much larger force over a larger area.
