  • ExtrusionWikipedia

    Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections and to work materials that are brittle because the material only encounters compressive and shear stresses.
