Types Of forging flange Processes

There are basically three methods (or processes) to make a forged part. For example: forged flange.

Impression Die Forging

Cold Forging

Open Die Forging

Seamless Rolled Ring Forging

Impression Die Forging: Impression die forging pounds or presses metal between two dies (called tooling) that contain a precut profile of the desired part. Parts from a few ounces to 60,000 lbs. can be made using this process. Some of the smaller parts are actually forged cold.

Cold Forging: Most forging is done as hot work, at temperatures up to 2300 degrees F, however, a variation of impression die forging is cold forging. Cold forging encompasses many processes -- bending, cold drawing, cold heading, coining, extrusions and more, to yield a diverse range of part shapes. The temperature of metals being cold forged may range from room temperature to several hundred degrees. stainless steel forged flanges Wholesale

Open Die Forging: Open die forging is performed between flat dies with no precut profiles are the dies. Movement of the work piece is the key to this method. Larger parts over 200,000 lbs. and 80 feet in length can be hammered or pressed into shape this way. duplex steel flange supplies

Seamless Rolled Ring Forging: Seamless rolled ring forging is typically performed by punching a hole in a thick, round piece of metal (creating a donut shape), and then rolling and squeezing (or in some cases, pounding) the donut into a thin ring. Ring diameters can be anywhere from a few inches to 30 feet. duplex steel fittings manufacturers
