The upset forging operation is used for parts having uniform cross section.
- It is also known as heading, and typically decreases the considerable length of a workpiece
- A standard bar of uniform cross section normally round is held between grooved dies in an upset forging.
- Sufficient pressure is exerted to the proper end in the specific direction of the axis of the standard bar properly employing a heading tool that typically spreads the end by gradual displacement of an active metal.
