Want to get a comparison between open die and ring rolled forging? Then continue reading to unfurl some interesting information!
An overview of the forging process
To make a forged part, there are four varieties of processes involved. They are;
- Impression Die Forging
- Cold Forging
- Open Die Forging
- Seamless Rolled Ring Forging
This article will brief you on the ring rolled, and the open die forging.
What is ring-rolled forging?
It’s a metal-cutting technology that involves punching holes into solid and thick round metal pieces and applying intense pressure to make them into thin rings. They are available in various sizes and are handy in multiple machine tools, turbines, pipes, and pressure vessels without alteration in the grain structure.
What is open-die forging?
Also known as free forging, open die forging involves the compression of a single heated metal between two dies. It is a metal networking process where the metal gets reshaped and used as simple tools. They are likely similar to the closed die process and get used to making parts like bars, rings, blanks, hollows, and spindles.
The ultimate comparison chart between open and ring-rolled forging
Most of the machinery used for construction, agriculture, automotive, and oilfield use forgings. So now let’s take a closer look at these two prime forging varieties for a better understanding;
| Ring rolled forging | Open die forging |
| The metal used gets pierced beforehand to form a hollow ‘doughnut’ shape. Then it’s heated and rotated to lessen the thickness and increase the ring diameter. | The metal used in this process is not limited by the impression it dies. |
| They are available in various sizes depending upon the utilization. | They are available in various sizes ranging from a few pounds to over 150 tonnes. |
| These are best for energy generation, mining, aerospace, off-highway equipment, and many other critical applications. | If you’re looking for optimum structural integrity for your design in a significant metal component, you can opt for this type. |
| The shape is mostly flat or vertical high walls with thickness ranging in ratios such as 1:16 up to 16:1. Even greater proportions are achieved upon processing. | The available shapes are square, round, rectangular, hexagonal bars, solid shafts, Contour-formed metal shells (pressure vessels), and hollow cylinders. |

| The cylindrical metal undergoes upsetting compression at a plastic deformation temperature and is then pierced, sheared, and placed on a mandrel. | The metal undergoes a heat of 500°F to 2400°F and gets the desired shape through hammering or pressing. |
| These rings are created from various metals like malleable material alloys, stainless steel, carbon, and aerospace metals. | Copper, nickel, and titanium alloys are used in this process. |
