Abstract
An object is extruded to have the form of a cage, the cage defined by spokes corresponding to several extrudate streams. The spokes bound a hollow interior and extend between opposed hub regions where the spokes are fused together. In manufacturing the objects, ceramic material is extruded through multiple dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extrusion to vary the position of extrudate streams exiting the dies.
Claims10
An extruded object of cage form defined by a plurality of spokes corresponding to respective ones of a plurality of extrudate streams, the spokes fused together at first and second hub regions, the spokes extending between the hub regions and bounding a hollow interior, each spoke being of generally uniform cross-sectional shape along the length thereof.
