Open Die Forging Aerospace Application

Have you ever heard of the term “smith forging”? Before all the advancements in tools and technology, forging was performed by a smith using an anvil and hammer to produce and create forged metal – hence, the term. Smith forging, commonly known as open die forging, is a process that involves a hammer striking and deforming a workpiece securely attached to a stationary anvil.

What is Open Die Forging?

Why do Aerospace Companies Prefer Open Die Forging?

The Basics

Open die forging involves the process of forging alloys without having to enclose the workpiece throughout the procedure. In this process, it is required that the operator knows the proper position and orientation of the workpiece to achieve the desired shape.

The dies or surfaces are normally flat in shape. However, there are instances when dies with a specific shape are used for specialized forging. For instance, a die may have a convex, concave, or round surface. It may also be a cut-off tool or a device to form holes.

Advantages of Open Die Forging

Aerospace companies consider the advantages of open die forging before choosing this metalworking process to produce aerospace parts and components. Below are the advantages:

  • Superior strength
  • Better-quality grain size
  • Constant grain flow
  • Enhanced microstructure
  • Improved fatigue resistance
  • Reduced chance of voids

Progressive open die forging techniques are capable of creating multiple shapes notwithstanding the large parts and components used. Simple shapes like rounds, ingots, and bars are easier to produce because of the constant grain flow and improved fatigue resistance.

The most common subjects used for smith forging are steel and related alloys. Nonetheless, other metals can be shaped as desired. These metals include titanium, nickel, and copper alloys.

Industrial or Commercial Aerospace Parts

The following are the parts and components used by aerospace industries that were produced and forged through an open die forging method:

  • Shafts
  • Seamless rolled rings (bearings)
  • Rotor/Propeller Parts
  • Landing gear components
  • Flat bar
  • Flanges
  • Disks

Open Die Forging | Difference Between Open and Closed 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

Open Die Forging | What Is the Process?

There are numerous different types of forging processes. There is rolled ring forging, which punches a hole in a thick, round piece of metal and then rolls and squeezes the part into a thin ring. There is also closed die forging, which moves two dies towards each other until they cover the work piece and create the desired part. Lastly, there is open die forging. However, you need to keep reading to learn more about this useful forging process!

The Open Die Forging Process

The open die forging process consists of deforming heated metal parts between a top die attached to a ram and a bottom die attached to a bolster, anvil, or hammer. The metal parts are worked at temperatures ranging from 500˚F to 2400˚F and are gradually configured into the desired shape through skillful pressing or hammering of the metal piece. This forging process often requires secondary machining and refining in order to achieve the tolerances for finished specifications.

Despite the need for additional machining, the open die forging process is extremely beneficial. The parts created by this process can range from simple to complex, including discs, sleeves, rings, cylinders, shaft, and more. It can even produce custom shapes. Furthermore, the repeated working of the material throughout the process increases the strength and grain structure of the finished product. Some other benefits of open die forgings include fatigue resistance and strength as well as reduction in voids.
