When it comes to types of forging, there are many. Rolled ring forging punches a hole in a thick, round piece of metal and both rolls and squeezes the part into a thin ring. Closed die forging involves moving two dies towards each other until they cover the workpiece and create the desired part. Then there is open die forging.
The Forging Process
Open die forging consists of deforming metal parts by heating them between a top die attached to a ram and a bottom die. The metal is worked at temperatures ranging from 500 °F to 2400 °F and slowly configured into the desired shape through pressing or hammering of the metal. The process usually requires a secondary machine or refining in order to get the tolerances for finished specifications.
What Comes Next?
Even though it needs additional work, open die forging is beneficial. It is used to create parts that are both simple and complex, such as:

One of the biggest benefits of this type of forging is the repeated working of the metal increases its strength and grain structure of the finished product. It also increases the product’s fatigue resistance and reduction in voids.
