  As manufacture processes become more complex, the direct extrusion of
material still remains a reliable method of fabrication and processing a
variety of materials, but most commonly ceramics. These materials are shaped by
a die that can determines the output shape of the material. A generic complex
die design was used to explore how varying the geometry of the die can affect
the overall and component pressures felt during the extrusion process, based on
a Benbow-Bridgwater model. From this we determined some general interactions
and relationships, comparing how varying geometries can lead to extrusions of
the same shape, and discuss how to balance this against desired effects that
the extrusion process may have on the material.
