Extrusion and Drawing
Extrusion
Material is forced through a die

• Almost any solid or hollow cross-section can be
  produced
• by extrusion
• Constant cross-section
• At room temperature or elevated temperatures
• (depends on ductility)

The Drawing Process
In drawing, the cross-section of a rod or wire
is reduced or changed by pulling it through a
die. The initial cross-section is usually round
or square.
