Often known as “impression die forging”, closed die forging involves two or more dies containing impressions brought together. The closed die forging process offers some distinct advantages over many forms of casting or open die forging from a manufacturing standpoint.

· Closed die forging usually supplies a more cost-effective process than open-die forging for the fulfillment of high volume production runs. This process can generate many small parts quickly.

· The process will help create shapes using virtually any type of commercial metal. For example, today manufacturers rely upon closed die forging to create parts made from steel, aluminum or brass alloys.

· Custom closed die forging typically supplies parts with better surface finishes than many other forging or casting processes. The parts generated through this process may require only minimal finishing.

· A manufacturer can utilize the process of closed die forging to produce both symmetrical and non-symmetrical metal parts. With the capability to reproduce almost any size and shape of part, this flexible forging process holds widespread appeal in modern manufacturing environments!

· Compared to most forms of forging, the process of closed die forging sometimes offers a way to create metal parts displaying superior mechanical properties. Under rigorously controlled manufacturing conditions, the internal grain structure of the metal components contributes to increased strength and tightness.

· Manufacturers may prefer closed die forging because parts do not require extensive machining afterwards. The manufacturer will need to trim away any flash. Yet the process of custom die forging may allow the generation of blind cores or nearly complete shapes requiring only the most minimal machining and finishing.

· A closed die forging manufacturing environment holds some practical daily maintenance advantages. Maintaining a tidy, clean work area typically requires less complicated clean up procedures than casting manufacturing locations demand.
