A honeycomb extrusion die includes an inlet face having a plurality of
feed channels, and a discharge face having an array of intersecting
honeycomb discharge slots. The extrusion die also includes a bonded array
of pin elements each exposed on the discharge face of the die and
juxtaposed to form the discharge slots of the discharge face and the
array of feed channels, wherein the discharge slots extend from the feed
channels, and wherein the feed channels communicate with the discharge
slots so as to guide an extrudable material toward the discharge face.
Each pin element includes a plurality of discharge slot surfaces, a
plurality of feed channel surfaces continuous with the discharge slot
surfaces for guiding the extrudable material toward the discharge face,
and a plurality of spacing surfaces for spacing each pin element from
adjacent pin elements.
