Abstract:
Methods for fabricating a honeycomb extrusion die from a die body include the step of machining extrusion slots with at least one grinding wheel to provide a honeycomb pattern of extrusion slots. In further examples, a plurality of the extrusion slots of the honeycomb pattern of extrusion slots can be machined with a wire electrical discharge machining process after machining the plurality of extrusion slots of the honeycomb pattern of extrusion slots with the grinding wheel.
