摘要： A honeycomb extrusion apparatus includes a die body and a mask defining a peripheral gap. The peripheral gap includes a first extrusion cross section at a first radial location relative to the extrusion axis and a second extrusion cross section at a second radial location relative to the extrusion axis. An overall flow area of the first extrusion cross section is less than an overall flow area of the second extrusion cross section. In further examples, methods include co-extruding a honeycomb body with an integral skin with the overall flow area of the first extrusion cross section being less than the overall flow area of the second extrusion cross section. In further examples, methods include compensating for different skin flow characteristics associated with a particular honeycomb network configuration of discharge slots in a die body.
