Forged rings are produced by a process called ring rolling on rolling mills. That’s the basic part, but there are several different types of forgings depending on what you are looking for. Here are some of the different types of forging processes.
Impression die forging pounds or presses metal between two dies that contain a precut profile of the desired part. Parts from just a few ounces to 60,000 lbs. can be made via impression die forging. It is also referred to as closed-die forging and forges steel, aluminum, titanium and other alloys. Impression die forging can produce a variety of 3-D shapes that range in weight from mere ounces up to more than 25 tons. The process is used to produce hydraulic presses and mechanical presses and hammers.
While the majority of forging is done at extreme heat, there is one that is done cold. Cold forging can make a wide variety of part shapes such as shaft-like components, cup-shaped geometry's, hollow parts with stems and shafts, and all kinds of upset and bent configurations. The process uses many steps such as bending, cold drawing, cold heading, coining, extrusion, punching, and thread rolling.
Open die forging is done between flat dies with no precut profiles is the dies. Larger parts over 200,000 lbs. and 80 feet in length can be hammered or pressed into shape this way.
