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.

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 | Where Can I Find the Best Open Die Forgings?

There are multiple types of forging processes. The two most common are open and closed die forging. While both share the same concept of using pressure and temperature, they differ in their use of dies to form the metal. Let’s take a deeper look at open die forging.

Open Die Forging

Open die forging is the process of deforming a piece of metal between multiple dies that do not completely enclose the material. It is often used for short-run forgings of parts that are simple in design. This can include discs, rings, sleeves, cylinders, and shafts. Products made via this process often need secondary machining and refining to achieve the tolerances required for the finished specifications. Custom shapes can also be produced with open die forging.

Industries That Use Open Die Forgings

Many industries utilize open die forgings. The agriculture, automotive, medical, industrial, consumer, aerospace, nautical, oil & gas, and military industries all use this process.

Forgings | Types of Forging Processes

Forgings are one of the most sought after metal components. At its most basic level, forgings are created by forming and shaping metals by hammering, pressing, or rolling. As a result, forgings come in a myriad of sizes and shapes with enhanced properties. Depending on your specific project and desired application, different forging processes are used to create the metal part. Keep reading to learn about the most popular forging methods!

3 Different Methods for Forgings

1. Rolled Ring Forging

Rolled ring forging is a process that uses two curved dies to deform the metal. Normally, the dies are two opposing rollers. This method produces forged products with a final shape that is similar to the dies. The rolled ring process is largely used due to its many benefits. Some of these benefits include a long lifespan, high productivity, low cost, and quality finishes.

2. Closed Die Forging

Closed die forging is a process that shapes a metal part by forcing it into the contours of a die. This process gets the name “closed die” because the material is confined between an upper and lower die. The closed die process requires a significant amount of force. It is often used to produce near net shapes.

3. Open Die Forging

Open die forging is a process that plastically deforms the metal with a series of compressive forces. It is carried out between two flat dies or simple shapes. Usually, the dies do not completely enclose the material, which is why this process is called “open die.” The open die forging method is used mostly for large objects and smaller quantities.

What is Open Die Forging? | Metal Manufacturing

Rolled ring forging, closed die forging, and open die forging are three of the most common metalworking processes. Although they are all forging methods, they are also all different. It is important to be able to tell these processes apart in order to determine which fits your specific needs. To help you out, here is everything you need to know about open die forging.

What You Need To Know About Open Die Forging

Open die forging, also known as free forging, is a metalworking process. It takes heated metal and compresses it between two dies. The metal is worked at temperatures ranging from 500°F to 2400°F and is shaped into the desired shape through hammering or pressing. Most of these forgings or made on flat dies, but V-dies, round swaging dies, pins, mandrels, and loose tools are also used depending on the specific part.

This method is very similar to the closed die forging process. However, open die forging is unique because the shape of the piece does not result from the shape of the dies used, but from repeated local forming with geometrically simple dies that are typically moved relative to the piece. This forging process gets it’s name because the metal is never completely confined in the dies.

Open die forgings produce strong, durable parts in sizes that range from a few pounds to hundreds of tons. As a result, it is a favorable method to produce large and simple parts such as bars, rings, blanks, hollows, and spindles. Open die forging is also a great open for custom metal components as well.
