Abstract
A honeycomb extrusion die () includes a die body () including an inlet face () and an exit face. The die body () has slot inlets () and a plurality of pins () disposed between the slot inlets () and the exit face. The plurality of pins () include side surfaces (B) configured to define a matrix of intersecting slots (), wherein the matrix of intersecting slots () has slot exit () widths at the exit face. Divots () extend into a plurality of the side surfaces (B) between the slot inlets () and the exit face. Each individual divot () has a divot depth (D) extending into a side surface (A,B,A,B) of the side surfaces (B). A ratio between a slot exit width (W) Wof an individual slot () and the divot depth (D) of an individual divot () extending into a side surface (A,B,A,B) of the individual slot () is greater than 1.2. Methods of forming honeycomb bodies with honeycomb structures are provided, as are other aspects.
