68.2. Problem Description

In this figure, the two primary process parameters are:

  • the extrusion ratio (the ratio of cross-sectional area of the undeformed cylindrical billet to the die exit), and

  • the die angle.

To maintain close contact (avoiding any fluid penetration in the contact), the cylindrical rod is tapered as (via the die angle) and fitted into the die as a plug.
