Closed Die Forging | All About the Closed Die Forging Process

In case you’re not familiar, forging refers to the manufacturing process that involves the shaping of a piece of metal with the use of compressive forces. A power hammer or a die delivers the blows. Today, it has become a major worldwide industry and its traditional products include hardware, kitchenware, cymbals, edged weapons, hand tools, and jewelry.

What is Closed Die Forging?

Â

Sometimes referred to as impression-die forging, this type of forging process uses dies that have the precut profile of the desired part. These dies move towards each other and partially or wholly covers the metal piece. The raw material that’s been heated is positioned in the bottom die. The shape of the forging as a negative image is incorporated in the top or bottom die. When the top die presses against the bottom die, the raw material forms into the desired shape. In case you’re wondering, this process can be used to produce parts from a few ounces to 60,000 lbs. You may also be surprised to find out that some of these smaller parts are forged cold.

 

What Are its Capabilities?

Â

Closed Die Forging of steel, titanium, aluminum, and other alloys can create a virtually limitless variety of 3-dimensional shapes that weigh from a few ounces up to over 25 tons. While closed die forges that are routinely produced on hydraulic presses have capacities up to 50,000 tons, those that were produced on mechanical presses have capacities up to 20,000 tons. Lastly, those that were regularly produced via hammers have capacities up to 50,000 lbs.

 

Since this type of forging process restricts metal flow due to the presence of the die contours, you won’t be surprised to know that Closed Die Forging can yield more complex shapes as well as closer tolerances compared to the open-die forging process. However, it’s important to note that if additional flexibility is required in forming symmetrical and non-symmetrical shapes, pre-forming operations that involve bending will have to be implemented on the piece of metal before it is forged in finisher dies.

Forgings | The Difference Between Open-Die Forging and Closed-Die Forging

When it comes to forgings, there are many different types. Two of the most popular types are open-died and closed-died forgings. Before selecting which production method is best for your next project, you need to know what each process does and their differences.

Open-Die Forging

Also known as free forging, open-die forging involves deforming a piece of metal between multiple dies that do not enclose the metal entirely. This allows the dies to hammer and stamp the metal into the desired shape. Open-die forging usually requires secondary machining and cannot create pieces with complex parts.

Closed-Die Forging

Closed-die forging, also known as impression forging, is very similar to open-die forging but differs in one key area. Instead of using dies that don’t entirely enclose the metal, closed-die forging involves dies that completely encapsulate the molten metal. This leads to parts that can be very complex while also being small. This method does not require any secondary machining too, which lowers the overall production cost.

Which is Best?

At the end of the day, it boils down to what you need the most. Both methods have their advantages and disadvantages. If you are trying to create a complex machine part or something that you don’t want to pay to have additional machining done, closed-die forging is for you. If you are trying to create a high number of products and need to do so quickly, maybe open-die forging is for you.

When it comes to ring rolled forgings, there is a lot you need to know. How are they made? What are they made from? Where can I find them in the real world? Can they help me with my next project? All of these questions and more can be answered below.

The Process

First, the starting stock is cut by weight and then rounded into its beginning shape. It is then upset to achieve the proper directional flow. After that, the workpiece is punched and the starting stock then begins to resemble a donut. This donut of molten metal is then ready for placement and rolling. The idle roller applies pressure to the starting stock while the axial roller and drive roll continually work the molten metal into the desired shape. Once the desired shape is achieved, the ring is cooled and set aside.

Benefits of Ring Rolled Forging

There are many reasons why you would want components made from ring rolled forging. For starters, the rings are usually extremely durable and can stand up to extreme conditions. Whether it is extreme heat, cold, or severe temperature change — rolled ring forging components are perfect for these environments.

Rolled Rings | How Ring Rolled Forging Works and Its Applications

When it comes to components created by rolled rings forging, they are typically much stronger and better at standing up to wear and tear that is standard in environments that undergo extreme temperatures. But how are they made? Where can they be found? We break it down for you below.

The Forging Process

First, the material is rounded and cut to size according to how much it weighs. It is then upset to reach the intended integrity, directional grain, and other specifications. The workpiece is punched and pierced to be the ring rolled process. After that, it is placed on the ring mill to be rolled. The idler roll applies pressure against the drive roll and slowly the ring diameters are increased. Continued pressure is applied, and this reduces the wall thickness. The axial rolls control the height as it is being rolled. This is repeated until the proper size and specifications are reached.

Benefits and Applications

There are a lot of benefits and applications to components created by this method. The most notable is how strong the final product is. The rings that are produced are stronger than other parts because they are extremely resistant to heat and other things that typically cause issues with other parts. Rolled rings are made from many different types of materials, such as:

  • Carbon
  • Stainless Steel
  • Alloy Steels
  • Haynes
  • Inconel
  • Super Alloys
  • Aluminum
  • Nickel Aluminide
  • And much more!

Because of how versatile these components are, you typically see them all over the place. They are common in any environment that is exposed to extreme temperatures and temperature changes.

what are rolled ring forgings?

Rolled Rings | How Are Rings Rolled?

Rings are typically rolled by a process called ring rolling. Ring rolling is done on rolling mills. They can be produced in configurations ranging from flat, washer-like parts to tall, cylindrical shapes, with heights ranging from less than an inch to more than 9 feet. Let’s take a look at the process for rolled rings and how they are made.

Ring Rolling Process

Starting Stock – The first step is the rounding of the starting stock. It is then upset to achieve structural integrity and directional grain flow.

Punching and Piercing – After being rounded and upset, the stock is then punched and pierced to achieve the doughnut shape needed.

Idler Roll – After the stock has been given its doughnut shape, the rolling itself can begin. The process begins with the idler roll applying pressure to the preform against the drive roll.

Increasing Diameter – The next step is to increase the diameter. That happens as the continuous pressure reduces the wall thickness. The axial rolls then control the height of the ring as it is being rolled.

The Size is Achieved – This entire process is repeated until the desired size is achieved. At this point, the ring rolling process is complete and you have a rolled ring in your desired size and shape.

what is the rolled rings process?

Rolled Rings | The Types of Rolling

The rolling process is a major metal forming manufacturing process. During the rolling process, the metal workpiece is compressed between a set of rolls where it reduces its cross section area and increases its length. Rolling is ideal for large length same cross-section workpieces. When it comes to rolling, there are several different types. Let’s take a look at the types of rolling, including rolled rings.

Ring Rolling

The ring rolling process consists of two rollers that rotate in the same direction to each other. The ring rotates due to the rotation of the roller and the rollers start to move closer to each other. An extra pair of edge rollers are used to maintain the height while the diameter changes. Ring rolling is used to make items such as bearing and turbines.

Skew Rolling

Skew rolling is done to make the ball of ball bearings. During this process, a round bar or wire is fed directly into specially designed rollers. These rollers continuously form spherical balls by rolling action. In addition to the ball of ball bearings, skew rolling is also used to make other types of small size spherical balls.

Transverse Rolling

Transverse rolling takes place when both rollers rotate in the same direction and the bar is fed transversely. This process is used to make items such as tapper shafts and leaf springs.

Seamless Rings | What Materials Are Used?

Seamless rings are created through a process called ring rolling, which uses a machine called a rolling mill. When it comes to the making of the seamless rolled ring, many different materials can be used. Let’s take a look at some of the different materials used to make seamless rolled rings.

Aluminum

Aluminum is incredibly popular in the aerospace, defense, and transportation industries. That’s because it has a low density and is extremely corrosion resistant. The ductility of aluminum makes it easy to forge. It also makes it susceptible to residual stresses though during the heat treating process.

Stainless Steel

Stainless Steel is used in a variety of industrial applications where moderate strength and enhanced corrosion resistance is required. Standard grade stainless steels forge easily and are less susceptible to residual stresses than other alloys. However, the more complex stainless steels require far more sophisticated forging techniques to optimize corrosion resistance and mechanical properties.

Alloy Steel

The majority of steel products used today are made from iron alloyed with carbon and other elements such as chromium, nickel, and molybdenum. The addition of carbon and other alloying elements has increased the strength of the metal by up to 1000 times.
