Abstract
An dome-shaped extrusion die for use in forming honeycomb monolith structures is disclosed. The die is formed by deforming an extrusion die having a flat cross section to obtain a dome-shaped cross section. Alternatively, the die may be fabricated from sinterable ceramic or metal powders in which case the holes and slots may be formed either in the green state, or in a chalk-hard state after partial densification.
