What Is Open Die Forging?
Open die forging involves the shaping of heated metal parts between a top die attached to a ram and a bottom die attached to a hammer, anvil or bolster. Metal parts are worked at their appropriate temperatures, ranging from 500°F to 2400°F, and gradually shaped into the desired configuration through the skillful hammering or pressing of the workpiece.

Difference between open die forging and closed die forging
While impression or closed die forging confines the metal in dies, open die forging is distinguished by the fact that the metal is never completely confined or restrained in the dies. Most open die forgings are produced on flat dies. However, round swaging dies, V-dies, mandrels, pins and loose tools are also used depending on the desired part configuration and its size.
spindle-shaped part open die forging process:
1. Starting stock cut to size by weight is first rounded, then upset to achieve structural integrity and directional grain flow.

2. A "fuller" tool marks the starting "step" locations on the fully rounded workpiece.

3. Forging or "drawing" down the first step to size. The second step is drawn down to size.

4. Note how the part elongates with each process step as the material is being displaced.

5. "Planishing" the rough forging for a smoother surface finish and to keep stock allowance to a minimum.
