Open Die Forging | What Is the Process?

There are numerous different types of forging processes. There is rolled ring forging, which punches a hole in a thick, round piece of metal and then rolls and squeezes the part into a thin ring. There is also closed die forging, which moves two dies towards each other until they cover the work piece and create the desired part. Lastly, there is open die forging. However, you need to keep reading to learn more about this useful forging process!

The Open Die Forging Process

The open die forging process consists of deforming heated metal parts between a top die attached to a ram and a bottom die attached to a bolster, anvil, or hammer. The metal parts are worked at temperatures ranging from 500˚F to 2400˚F and are gradually configured into the desired shape through skillful pressing or hammering of the metal piece. This forging process often requires secondary machining and refining in order to achieve the tolerances for finished specifications.

Despite the need for additional machining, the open die forging process is extremely beneficial. The parts created by this process can range from simple to complex, including discs, sleeves, rings, cylinders, shaft, and more. It can even produce custom shapes. Furthermore, the repeated working of the material throughout the process increases the strength and grain structure of the finished product. Some other benefits of open die forgings include fatigue resistance and strength as well as reduction in voids.
