ABSTRACT:
In the extrusion of a material, which can be a metal feedstock, through a die means by maintaining frictional engagement of the material with passageway defining surfaces of a member which is moved towards the die means such that frictional drag of the passageway defining surfaces urges the material through the die means, the improvement of enhancing the resultant available extrusion force by either increasing said frictional drag or reducing the frictional resistance to movement of said material relative to non-moving parts of said passageway, or a combination of both.
