Open Die Forging | Difference Between Open and Closed Die Forging

what is open die forging?

Forgings are popular in a variety of industries. Construction machines, agricultural machinery, automotive, and oilfield equipment all use forgings in some capacity. When it comes to forgings, there are two main types: open die and closed die. Let’s take a look at the difference between open die forging and closed die forging.

Open Die Forgings

The open die forging process involves deforming a piece of metal between multiple dies that do not completely enclose the material. The metal is altered as the dies “hammer” or “stamp” the material through a series of movements until the desired shape is achieved. Products formed through this type of forging often need secondary machining and refining to achieve the tolerances required for the finished specifications. Benefits include:

  • Being able to produce a small quantity
  • Being able to create custom shapes
  • Good fatigue resistance and strength of products

Closed Die Forgings

Also known as impression die forgings, closed die forging compresses a piece of metal under high pressure to fill an enclosed die impression. In some cases, a second forging operation is then required to reach final shapes and dimensions. Benefits of this type of forging include:

  • Being ideal for producing large quantities
  • Precision when creating shapes
  • High-quality surface finish
