Advantages and Disadvantages of Closed Die Forging

Otherwise known as impression-die forging, closed die forging relates to a process in which a metal is placed between shapes that are customized to fit the metal. Such metal is then pressed and hammered, causing it to fill and flow in the cavities of the custom-shaped dies. This forging classification is one of the most frequently used processes for forging steel components.

Closed die forging can produce longer-lasting and stronger products because it works well with the steel’s internal grain structure.

Why is Closed Die Forging Frequently Used?


The noteworthy advantage offered by closed die forging is that it needs little-to-no machining at all. It simply makes use of the force produced from all the pressing and hammering during the closed die forging process. Likewise, it uses the right amount of heat to deform the steel so it can accurately fill the die mold or impression.

Closed die forging can be used to create parts made out of almost all metal materials, including steel, aluminum, and countless other metal alloys. Thanks to no material limitations, parts can be made to fit your exact needs. Other advantages of closed die forging are:

  • Capacity to create near net shape and sizes
  • More accurate and steady impressions
  • Can achieve several shapes and dimensions have tight tolerances
  • Superior mechanical properties and better surface finish


Just like everything in life, there are some disadvantages to products – that includes closed die forgings. Some of the common disadvantages include:

  • Size limitation
  • It is not cost-effective for short production runs for the high tooling cost
  • Shape limitation – For these components with an irregular shape, it is also not available
  • Such complex products can only be made by casting

Closed Die Forging | 9 Facts to Know

Have you heard of forging? If not, it’s a manufacturing process that uses compressive forces to shape metal parts. There are many different kinds of forging processes to choose from. As a result, it’s important to know a little about each process. Today we’re going to discuss a popular method of forging called closed die forging. Here are some interesting facts to know!

Facts About Closed Die Forging

closed die forging

  1. The process of forging is also known as “impression die forging.”
  2. The history of this forging process dates all the way back to 4000 BC. And some believe it may have come about even earlier than that.
  3. This process can forge most metals and alloys.
  4. This kind of forging has low recurring costs for the different parts, making it one of the most economical methods to use.
  5. Due to its economical advantages, this type of forging process is very popular in the automotive and tool industries.
  6. In comparison to many other machined parts, closed die forgings have a 20 percent higher strength-to-weight ratio.
  7. This forging process requires little to no machining. As a result, people are able to save significant time and money when using it on a project.
  8. Closed die forgings of stainless steel, titanium, aluminum and other metals have the ability to create several different 3-D parts with a variety of shapes, sizes and weights.
  9. Due to its unique flexibility, this type of forging process is one of the best processes for designs and shapes that are elaborate and complex.
