Hot Forging

This group of processes involves the application of pressure to material that has been or is being heated to allow forming whilst still in the solid state. Pressure is applied via Dies, Moulds or Forming Hammers and Heads.

The main variable distinguishing between these processes is the type of forming tool, whether it be a Closed Mould Tool, or an Open Tool requiring manipulation to impart shape into the component. 

The Forging action or pressure can also be a variable, however each process in this category encompasses every form of forging pressure or hammer application such as "Horizontal Counter-Blow" Forging.

The other major variable is the Form produced and the localised nature of forming. For example, Rings are forged using specific machinery that cannot easily be deployed for creating any other form. In terms of the localised nature of forging, this refers to Upset Forging - which deforms only part of a component, as with the production of studs, bolts and fasteners that are "Headed".
