随着制造工艺变得越来越复杂，材料的直接挤出仍然是制造和加工各种材料的可靠方法，但最常见的是陶瓷。这些材料由模具成形，该模具可以确定材料的输出形状。一个通用的复杂的模具设计用于探索如何改变模具的几何形状可以影响整体和组件的压力，在挤出过程中感受到的，基于一个Benbow-Bridgwater模型。由此，我们确定了一些一般的相互作用和关系，比较了不同的几何形状如何导致相同形状的挤出，并讨论了如何平衡这与挤出过程可能对材料产生的预期影响。
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.
