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
