ABSTRACT:
The invention relates to the manufacture of a body of a cellular structure by extruding a ceramic material through a die. The die comprises a succession of coaxial components (6, 10) fitted one round another, with two adjacent components defining between them longitudinal ducts (2) whose downstream ends communicate with an annular duct (3) and wherein the bottoms of said coaxial components fitted one round another have essentially radial notches (4) level with the annular ducts, the width of said notches being less than that of the longitudinal ducts, so that the ceramic material which flows through said longitudinal ducts is evenly distributed in the annular ducts and in the radial notches to form a body with a cellular structure directly on extrusion.
The invention has application to thin-walled honeycomb ceramic structures.
