More Information
Summary:Honeycomb extrusion dies for the extrusion of honeycomb ceramics of high cell density and reduced cell wall thickness are machined from fully consolidated powder metallurgy (P/M) stainless steels, providing dies with reduced feed hole roughness, improved feed hole straightness, and superior discharge slot finish, with the result that significantly enhanced extrusion performance and higher quality honeycomb extrusions are realized.
