The forging press is a machine that uses pressure to shape metal. The process of forging generally involves taking a piece of metal and using high pressure to hammer, roll, or otherwise deform it into the desired shape. forging presses are one type of machine used in hot forming, which is the process of shaping metal at high temperatures. forging presses can be used to create a variety of shapes, including discs, washers, rings, and other simple shapes. More complex shapes can also be created by combining several basic forge press operations.
