Precision Rolled Ring Forging and Copper

The rolled ring process minimizes copper material usage used in the manufacture of annular ring forgings. Raw copper material is pierced or punched from its center and then placed on a mandrel and drawn out circumferentially to create a ring. Like copper open die forging‚ there is a lot of flexibility in the size and shape of the copper products that you can make. Circumferential grain flow ensures that the strength and reliability of your copper part is maintained by this process. The advantages of using the rolled ring process include:

• -Cost savings over the closed die process in that no additional tooling charges are required
• -Effective process for low volume or larger-sized copper rings
• -Significant copper material savings compared to the use of plate‚ for example a 32¨ OD x 21¨ ID x 3¨ thick ring would yield over a 66% material savings using the rolled ring process.
• -The machining required is minimized because this process brings the copper product to a near net shape.
