Process Forging
Forging produces complex free-form geometry in metals. It is a near-netshape process that generates most of the final part surface. Additional material in the overflow fins need to be cut off and holes are drilled into the correct diameter.

The forging process reduce the amount of material waste and therefore reduces the material cost. It also improves production speed and gives a more favourble grain orientation in the finished part. Often higher strength is achieved.

In forging the workpiece is compressed between two dies. Often the workpiece is heated in order to reduce strength and increase ductility during the deformation.Due to the large forces are the dies relatively expensive.

Price notes Tooling investments (dies) are relative high, but for larger productioin volumes the part cost is compettitive to machining.
