closed-die forging

Closed-die forging is a metalworking process used to shape metal and enhance its strength by forcing a heated workpiece between two dies. This method is typically performed hot to reduce the force required and increase the metal's plasticity.12

In closed-die forging, the metal is enclosed on all sides by the walls of the two dies as they come together. This process often involves multiple dies to gradually shape the metal from an initial bar into the final complex form. A key advantage of closed-die forging is its ability to produce parts with precise tolerances, minimizing the need for subsequent machining.2

Metallurgy, the science of making useful products from metals, encompasses various forming methods, including forging, casting, and powder metallurgy, each chosen based on desired properties and cost-effectiveness.2
