Abstract: Methods of manufacturing an extrusion die (100) having a plurality of pins (600a-c) and a plurality of slots (601) defined by the plurality of pins, each pin having a base, the method including applying a coating material (604) over side walls of the bases of the pins of the extrusion die and removing a portion of the coating material coated over the side walls of the bases of the plurality of pins with a cutting tool (650). In some embodiments, the cutting tool has a cutting width (652) equal to a target slot width (640) of the slots. In some embodiments, applying the coating material over the side walls of the bases of the pins includes overcoating a coating material to a thickness that is greater than a thickness needed to define a target slot width of the slots.
