Closed die forging is a metal forming process in which a billet or preform is placed between two dies, which are then brought together under high pressure to shape the material into the desired form. The dies are typically made of hardened steel and are machined to have a precise shape, so that the finished product has a high degree of accuracy and repeatability. The term “closed die” refers to the fact that the billet is fully enclosed within the dies and cannot move or escape during the forging process.
The process of closed die forging typically involves several stages, including preheating the billet to a temperature that is suitable for forging, placing the billet in the dies, and applying pressure to shape the billet. The pressure is typically applied using a forging press or hammer, and the final shape of the product is determined by the shape of the dies.
Closed die forging offers several advantages over other metal forming processes, including higher strength and toughness, improved dimensional accuracy, and the ability to produce complex shapes. It is commonly used in the manufacture of components for various industries, such as automotive, aerospace, and construction.
Closed die forging is commonly used in the manufacture of a wide range of components, including gears, shafts, valves, and other components for various industries, such as automotive, aerospace, and construction. The process offers several advantages over other metal forming processes, including higher strength and toughness, improved dimensional accuracy, and the ability to produce complex shapes. Additionally, closed die forging can be used to produce parts with a high degree of detail, such as small ribs or intricate patterns.
