Closed Die Forging vs Open Die Forging

Most manufacturers use the closed die forging technique when they need to forge metallic parts that are small or medium-sized. The fact that multiple elements and factors are being merged during the process of forging leaves us no reason to wonder why this technique is able to generate results that are geometrically accurate. However, before resulting in a closed die forging technique, it is essential to first determine the difference between open die or closed die forging.

Common Information to Know About Die Forging

What is it?

Free forging, commonly known as open die forging, is the method of deforming the metals between the several dies. It is called open die forging since the multiple dies do not entirely enclose the metal. These dies often hammer the metal through a chain of movements. It tends to alter the dimension of the metals until the dies reach the desired shape.

On the other hand, closed die forging is also called an impression forging. It takes advantage of a specific amount of pressure to force the metal piece into an encircled or bounded die. This process uses an induction heating furnace with medium frequency to heat the metal to reach the desired pattern.

Advantages and Disadvantages

In whatever you purchase or manufacture, one of the important factor to look into are the advantages or disadvantages of the product. Die forging is the perfect method to achieve maximum tolerance. When it comes to open die forging, it is cost-effective since it uses less material waste. Additionally, it offers reduced chances of voids in your final forging, can increase strength to achieve longer product life, improved microstructure, and has an excellent fatigue resistance.

In contrast, closed die forging offers excellent net shapes, tighter tolerances, and better surface finish. It is resorted to so there can be no material limitation and it will be economically beneficial when it comes to large runs.

Seamless Rolled Ring Forging | The Basics About Manufacturing Forged Steel Rings

Are you working on a project that requires the use of seamless rolled ring forging? The process of creating a seamless rolled ring involves the creation of a circular piece of metal that’s pierced at the center. Through open die forging, the metal is formed into something that’s shaped like a doughnut before it’s heated between 400 and 700˚C. Next, it’s placed on a mandrel or idler roll that increases the steel ring’s diameters and reduces the thickness of its walls. As the idler or mandrel roll pushes the ring’s walls outward, a wide range of shapes and sizes can be formed.

What are the Properties of Rolled Ring Forging?

The process that involves heating the doughnut-shaped metal above recrystallization temperature significantly improves the metal’s grain pattern. This increases the strength and resistance of the seamless rolled ring forging. Furthermore, the durability of this product allows it to maintain its shape when it is exposed to extreme fluctuations of temperature. Lastly, seamless rolled rings are also known to be cost-effective because they require less labor, machining, and raw materials compared to other alternatives.

What are the Common Applications of Rolled Rings?

In case you’re wondering, these strong, durable, and cost-effective metal components are widely used in various industries such as aerospace engineering, mining, as well as power generation. They are also extremely useful in manufacturing custom pressure vessel components which include valves, couplings, bearings, and forged flanges.

Closed Die Forging | Why Closed Die Forging is the Best Manufacturing Technique

Most manufacturers use the closed die forging technique when they need to forge metallic parts that are small or medium-sized. The fact that multiple elements and factors are being merged during the process of forging leaves us no reason to wonder why this technique is able to generate results that are geometrically accurate. Here are some of the reasons why forging is one of the most popular options in the metalworking industry:

Strength and Durability

In terms of strength and durability, the finished products of closed die forging come first. Thanks to the internal structure, the continuity of the grain is maintained. If you’re interested in producing high-performance products that are both strong and durable, use the close die forging manufacturing technique.

Production of Net Shapes or Near Net Shapes

Forging dies are typically precision-machined that’s why their finished products are the net shape or near-net shape. When you use forging, less post-forging operations are required because near-net shape products are produced. In other words, you’ll save a significant amount of time and effort.

Cost-Effectiveness

Since forging creates products that feature close tolerance with optimum surface finish, the need for post-machining operations and finishing is greatly reduced. This implies that you’ll get to spend less money for mass volume production.

Versatility with Components

One of the best things about forging is its versatility and adaptability with its components because the manufacturer can use any form of raw metal or even alloys using this method. It doesn’t matter if the user needs small or medium-sized metal parts – closed die forging can easily produce them.

Closed Die Forging | Applications for Open and Closed Die Forging

Over the years, the forging industry has tremendously evolved. The use of various techniques and processes gave rise to applications in industries such as construction, agricultural, automotive, machinery, and so much more. Furthermore, the two most popular forms of forging are open die forging and closed die forging. Although both are rooted in the fundamental forging process that involves beating a piece of metal until the desired shape, strength, and granular level are achieved, these two processes have branches in different directions.

What is Open Die Forging?

Sometimes called free forging, the open die forging process involves the placement of a piece of metal between multiple dies that don’t entirely close the metal. Through a series of movements, the dies hammer and stamp the material to change its dimensions until the required shape is attained.

What is Closed Die Forging?

Closed die forging is also called impression forging. It uses pressure to compress a piece of metal so that it will fill an enclosed die impression. It also involves the use of a medium frequency induction heating furnace for applying heat to the metal until the desired shape is achieved.

What are the Applications of Both Open and Closed Die Forging?

The end products of both processes look different from each other in terms of size. The forging process alters the metal at a granular level as continuous force is being applied via the beating process. Since open die forging doesn’t involve a fixed die size, this method works best for creating larger and heavier metal components that don’t require much machining to produce ultra-finished products. Among these large components are rollers and shafts that are used in railways. On the other hand, closed die forging is ideal for applications that require a high degree of precision such as forged fittings or automotive parts.

Rolled Ring Forgings | The Fundamentals of Seamless Rolled Ring Forging

Do you need parts for your flanges? Are you trying to work on a pressure vessel connections forging projects? If your answer is yes to these questions, you’ll need to know more about seamless rolled ring forgings that are made of steel because they’re perfect for both situations.

How Forged Steel Rings are Made

The process of manufacturing seamless rolled ring forgings starts with a circular piece of metal that’s been cut to the required weight before being rounded out. Through the open die forging process, the circular metal is then pierced at the center to produce a hollow shape of a doughnut. Before it is placed on the mandrel or the idler roll, it needs to be heated above recrystallization temperature which is usually between 400 and 700˚C.

The Next Steps

Once the heated metal is on the roll, the walls of the doughnut are pushed outward in order to reduce the thickness of its walls and increase the steel ring’s diameters. In case you’re wondering, the roll has the capacity to produce a wide array of shapes as well as proportions. In most cases, seamless rolled ring forgings that are made of steel have a thickness-to-height ratio between 1:16 and 16:1.

What are the Properties of Seamless Rolled Ring Forgings?

Seamless rolled ring forgings are known for their higher strength and resistance because the steel’s grain pattern is significantly improved by the recrystallization process. Furthermore, these forged steel rings are also durable because their ability to resist deforming from heat allows them to maintain their shape even when they’re subjected to drastic temperature fluctuations. Also, seamless rolled ring forgings are cost-effective because they require less machining, raw materials, and labor compared to similar components because the steel ring’s shape doesn’t change much during the entire duration of the manufacturing process.
