CGC Kymon explains its open die forging technique that helps produce high strength, long life parts.
This open die forging technique involves the shaping of heated metal parts between a top die attached to a ram and a bottom die attached to a hammer anvil or press bed.
In CGC Kymon’s open die forging technique, metal parts are worked above their recrystallisation temperature and gradually shaped into the desired configuration through the hammering or pressing of the work piece.
CGC Kymon’s open die forging is distinguished by the fact that the metal is never completely confined or restrained in the dies. Most open die forgings are produced on flat dies. However, round swaging dies, V-dies, mandrels, pins and loose tools are also used depending on the desired part configuration and its size. Although the open die forging process is often associated with larger, simpler-shaped parts such as bars, discs, rings, hollows or stepped bars, CGC Kymon’s open die forging is considered the ultimate option in custom-designed metal components.
High-strength, long-life parts optimised in terms of both mechanical properties and structural integrity are today produced in sizes that range from a few kilos to many tonnes in weight. In addition, CGC Kymon’s advanced forging techniques now offer shapes that were not possible previously.
