Geometric Pressure Minimisation of a Theoretical Die for Ceramic Extrusion

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.
