Different coatings along the die flow path cut wear and extrusion pressure while improving flow uniformity and ceramic article quality.
A one-piece extrusion tool uses slots, recesses, and inserted elements to form honeycomb cells with uniform flow resistance and simpler manufacturing.
Overcoating die pins and cutting back excess material sets precise honeycomb slot widths while removing nodules and improving wear resistance.
A layered die pairs machinable metal with a higher-modulus support plate to resist deflection, prevent pin flowering, and keep web thickness uniform.
Insert teeth into linear die slots to block selected flow paths, enabling complex honeycomb patterns without slow, costly plunge EDM.
A layered die pairs a high-modulus upstream plate with a metal discharge plate to resist deflection and keep honeycomb slot and web geometry uniform.
