    摘要： 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.

    摘要： Extrusion systems and methods with temperature control are disclosed. The ceramic batch material is flowed through a front section wherein the temperature of the batch material is locally adjusted through its perimeter at multiple locations. The temperature-adjusted ceramic batch material is then extruded through the extrusion die to form the extrudate. Temperatures of the extrudate at multiple outer surface locations having different azimuthal positions are measured. The temperature adjustment of the ceramic batch material is then controlled in a first feedback loop to control the shape of the extrudate based on the measured outer surface temperatures. The front section can also be cooled using a second control loop.

    摘要： A honeycomb extrusion die body (401) including inlet (414) and exit (402) faces, and a plurality of pins (406) on the exit face (402) defining a matrix of intersecting wide slots (425) and narrow slots (427). The wide slots (425) have an exit width (W1) greater than an exit width (W2) of the narrow slots (427). The die body (401) further includes feedholes (422) at the inlet face (414) and intersecting with inlet portions (416) to the wide slots (425) and/or the narrow slots (427). Some of the pins (406) defining the wide slots (425) include a first surface indentation feature (430) that is (i) located between the inlet portion (416) and the wide slot exit and (ii) spaced away from the wide slot exit. Some of the pins (406) defining the narrow slots (427) include a second surface indentation feature (434) that is (i) located between the inlet portion and the narrow slot exit and (ii) spaced away from the narrow slot exit.

    摘要： A honeycomb extrusion die (120) includes a die body (342) including an inlet face (315) and an outlet face (341). A plurality of pins (330) extend from the die body (342), wherein the pins (330) are arranged to define primary (312P) and secondary slots (312S). Primary slots (312P) include primary slot inlets (320P) and primary slot outlets (3120) and the secondary slots (312S) include secondary slot inlets (312SI) and secondary slot outlets (312SO). Feedholes (317) extend within the die body (342), the feedholes (317) including feedhole outlets (319), wherein the feedhole outlets (319) intersect only with the primary slot inlets (320P). First surface indentation features (345) extend into side surfaces (332) of the plurality of pins (330) defining the primary slots (312P). The first surface indentation features (345) are spaced from the primary slot outlets (3120). The secondary slots (312S) are devoid of surface indentation features. Other die bodies, extruders, and methods are disclosed.
