Closed Die Forging

CFP has truly taken the art of closed-die hot forging and turned it into a precise science. We work with clients in many industries to bring fresh products to the market quickly and cost-effectively. Contact Cerro Fabricated Products if you would like to discuss a closed die forging project with our team.

What is a Closed Die Forging?

A closed die forging, sometimes called an impression die forging or near net shape forging, involves a malleable billet of metal being placed between two die halves. The bottom die half is stationary. The top die comes down to compress the malleable billet. When this happen, the billet is dispersed and the metal moves to fill in both die half cavities.

This process works with the billets internal grain structure to produce stronger and more longer lasting parts than that same part machined from billet material or from a casting.

Benefits of Closed Die Forging

  • Better surface finish and superior mechanical properties
  • Less machining due to a closer net shape to the final geometry of the part
  • Cost effective for larger production runs
  • Dimensions with tighter tolerances can be achieved
  • More precise and consistent impressions can be achieved
