What is Friction about?
Bulk metal forming by extrusion involves forcing a heated metal billet through a die opening to produce a part with a fixed cross-sectional profile. There are two main types of extrusion - direct extrusion where the billet moves in the same direction as the ram, and indirect extrusion where the billet is stationary. Direct extrusion requires higher forces due to friction between the billet and container wall. Extrusion can produce parts with complex shapes and works well for brittle materials. Common materi
