Closed Die Forging

Closed Die Forging is a precision forging process in which heated metal is placed into a die cavity that fully encloses the workpiece, allowing it to take the exact shape of the die under high pressure. Also known as impression-die forging, this method refines the metal’s grain structure, significantly enhancing strength, toughness, and fatigue resistance. Closed die forging is widely used to produce high-performance components such as gears, shafts, connecting rods, and industrial machinery parts. It ensures excellent dimensional accuracy, uniform mechanical properties, and long service life, making it ideal for demanding automotive, aerospace, and heavy engineering applications.
