The closed-die forging process – Forging the Metal


Following on from part three of the closed-die forging process (heating the metal), we’re taking a look at the next step, forging the metal.

Summarising closed-die forging

Closed-die forging is where the dies (moulds) push towards each other covering the heated metal in whole or in part. Repeating this process transforms the metal into the shape of the die.

Why should you choose closed-die forging?

  • Increase the tightness and strength of product
  • Cost effective for large runs
  • Works with almost all metals

What happens in the closed-die forging process?

After the mould has been created and metal chosen, the forging process can begin. Firstly it’s heated to the right temperature (as discussed in the previous blog) and then it’s ready to be moulded.

It is transported using specialist tongs and placed within the closed-die forging dies. The raw material used is approximately the same size as the finished part.

The dies come together forcing the impact on the heating metal, pushing it into the shape of the mould. This action is like a hammering process and the dies close a fair few times until the metal is fully formed.
