A mixing segment for an extrusion apparatus comprises a shaft and a plurality of plow elements aligned along a helical path extending about a rotation axis of the shaft. Each plow element includes an outer peripheral arcuate ramp extending radially outwardly along the helical path from a root to an outer tip of the plow element. Methods of manufacturing a mixing segment and methods of manufacturing a honeycomb structure with an extrusion apparatus are also provided.

A twin screw extruder includes a barrel having a chamber, a discharge port, an extrusion molding die coupled to the discharge port of the barrel, axially extending first and second screw shafts, and a screw shaft support. The screw shaft support includes first and second spacer bearings disposed on the first and second screw shafts, and a first cross member including first and second loops slidably coupled to the first and second spacer bearings. A second cross member is spaced apart from the first cross member by a connection member, and also includes first and second loops slidably coupled to the first and second spacer bearings. The connection member is situated between the first spacer bearing and the second spacer bearing, and connected to the first cross member and the second cross member.
