Have you always wondered about how rolled ring forgings are produced or the difference between open die forgings and seamless rolled ring forging? If so, let’s explore the differences between these two types of forging processes.

What is Open Die Forging?

Open die forging that is sometimes called free forging refers to the process that involves a piece of metal that’s being deformed between multiple dies that don’t enclose the material entirely. In other words, it got its name because of the fact that the metal that’s being used is free and is not completely confined by impression dies that restrict its form. Due to the nature of its production process, open die forging allows for a wide range of shapes and sizes. In fact, it is capable of forming forgings that are only a few pounds heavy to massive 150-ton pieces.

What is Seamless Rolled Ring Forging?

Seamless rolled ring forging starts with a circular preform made out our metal that’s been pierced in the middle in order to form a hollow shape that looks like a doughnut. To increase its diameter or lessen the thickness of its walls, this ring is rotated as heat is being applied to it. Rolled ring forgings that are created through this process are known to be sturdier and more reliable compared to other parts. They also feature better heat tolerance and users can be certain of the maximum heat that these rolled ring forgings are able to withstand. Most importantly, they’re also manufactured at a lower cost than other comparable products since less machining is required.
