摘要： A honeycomb extrusion die comprising at least some slots (308) each with a divot (312) spaced toward a discharge surface (324) from a feedhole-slot intersection (332) and a wide portion at the discharge surface extending into the die body (358) 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.
