In impression- and closed-die forging, two or more dies are moved towards each other to form a metal billet, at a suitable temperature, to the shape given by the die impressions. The physical phenomena that occur during forging are highly complex and interdependent. It is therefore useful to review here the variables of the forging process and their interactions before actually discussing the problem of forging dies.
