An extrusion die and process for the extrusion of extrudates, particularly from ceramic pastes, having relatively small, closely spaced, through passages has a core support plate (18) extending across the inlet region of the die housing (10), and a plurality of flexible core members (32) extending from the plate to the outlet region (22) of the housing (10). The cross section of the flexible members (32), at least at the ends remote from the plate, corresponds to the desired passage cross section. The plate has feed channels (28) therethrough for the passage of the material being extruded to the downstream side of the plate. In the process the flexible members (32) approximately follow the lines of material flow so that they assume the desired disposition at the die outlet. |
