Abstract: A system for controlling center-to-outer flow distribution of extrudate source material through an extrusion die suitable for production of a honeycomb extrudate, and a method for fabricating a honeycomb extrudate, are provided. Sequentially arranged first and second plates define first and second pluralities of openings through which extrudate source material may flow, wherein at least some openings of the second plurality of openings arranged at different radial positions differ in area. Relative movement between the first plate and the second plate may be effectuated to adjust overlap between corresponding openings of the plates, thereby adjusting a center-to-outer flow distribution of extrudate source material through an extrusion die arranged downstream of the first and second plates.

Abstract: A method of making ceramic bodies includes systematically orienting the bodies during firing relative to a temperature gradient in a kiln. The systematic orientation of the bodies relative to the temperature gradient can allow for an average deviation of a measured shape of the ceramic bodies from a predetermined target contour shape to be less than what they would be if the bodies were oriented randomly relative to the temperature gradient.
