Abstract: A honeycomb extrusion die assembly (10) comprising a honeycomb extrusion die (701) and a forming plate (800) to block batch flow to at least a portion of a skin forming region. The honeycomb extrusion die (701) comprising a step cut discharge surface (758, 760) in the skin forming region and at least some slots (722) each with a divot (312) spaced toward a discharge surface (710) from a feedhole-slot intersection and a wide portion at the discharge surface (710) extending into the die body to the divot (312) to strengthen a peripheral region of a honeycomb extrudate in a reinforcement region, and a bulk nominal section corresponding to a bulk region of the honeycomb body.
