Closed die Forging

This process is also referred to as “impression die forging”.
Steel is heated to a high temperature (below its melting point but high enough to create plasticity in the material) and it is pressed or formed by a press into a die or mold.

Closed die Component Properties

  • Good Dimensional accuracy and repeatability in the manufacturing process
  • Good use of material, very little waste
  • Generally smaller components manufactured with this process
  • High production rates
  • Limitations
  • Can be expensive due to die costs
  • Some machining usually necessary
