Abstract: An extrusion system (100) according to certain aspects includes at least one infrared emitting device (102) arranged in a generally cylindrical shape with a hollow interior. The at least one infrared emitting device (102) is positioned downstream of an outlet of an extrusion die (110) to irradiate a perimeter of wet extrudate material in a uniform manner to form stiffened wet extrudate material (116) before such material is received by an extrudate support channel (118). The at least one infrared emitting device (102) generally uniformly stiffens the skin of the wet extrudate material (116) to resist mechanical deformation of the extrudate material during subsequent handling steps. Such skin stiffening allows for increased tolerance of handling forces and permits extrusion of softer wet extrudate material without compromising the shape of a fired ceramic product.

Abstract: A honeycomb structure (110) includes intersecting porous walls (106). Inlet channels (108i) and outlet channels (108o) are formed by the intersecting porous walls (106), wherein the inlet channels (108i) comprise inlet hydraulic diameters (HDi) and the outlet channels (108o) comprise outlet hydraulic diameters (HDo). The inlet channels (108i) comprise inlet corners (220i) with inlet corner radii (Ri) and the outlet channels (108o) comprise outlet corners (2200) with outlet corner radii (Ro). A centerpost (124) is defined by adjacent opposing inlet corners (220i) of two of the inlet channels (108i) and adjacent opposing outlet corners (2200) of two of the outlet channels (108o). A first diagonal length (D1) is a shortest distance between the opposing outlet corners (220o) of the two outlet channels (108o) and a second diagonal length (D2) is a shortest distance between the opposing inlet corners (220i) of the two inlet channels (108i). The honeycomb structure (110) has certain aspect ratios D1:D2 depending on hydraulic diameter ratios HDi:HDo.

Abstract: A system (100) for manufacturing an extrudate (10), such as a honeycomb body, is provided. The system comprises an extruder (102). The extruder is configured to form an extrudate from a wet mixture, such as a ceramic forming mixture. The system further comprises a radiative heat assembly (104). The radiative heat assembly is configured to heat the extrudate. The radiative heat assembly comprises one or more IR light sources (112). The one or more IR light sources are arranged as one or more rings around the extrudate. The system further comprises a differential pressure assembly (108). The differential pressure assembly is configured to remove at least a portion of water vapor from around the extrudate. The differential pressure assembly can direct an air flow out of a chamber (136) formed by a housing (132) surrounding the radiative heat assembly. Alternatively, the differential pressure assembly can direct an air flow into the chamber.

Abstract: A thin-walled honeycomb body (100) having a plurality of repeating cell structures (110) formed of intersecting porous thick walls (112V, 112H) and thin walls (114V, 114H). Each repeating cell structure (110) is bounded on its periphery by the thick walls (112V, 122H) of a first transverse thickness (Tk) and the thin walls (114V, 114H) have a second transverse thickness (Tt) that subdivides each repeating cell structure (110) into between 7 and 36 individual cells (108). In the thin-walled honeycomb body (100), the first transverse thickness (Tk) of the thick walls (112V, 112H) is less than or equal to 0.127 mm (0.005 inch) and the second transverse thickness (Tt) of the thin walls (114V, 114H) is less than or equal to 0.0635 mm (0.0025 inch), and Tk>Tt. Honeycomb extrusion dies and methods of manufacturing the thin-walled honeycomb body (100) having thick walls (112V, 112H) and thin walls (114V, 114H) are provided.

Abstract: A method of forming a glass article includes drawing a glass ribbon from a draw housing in a downstream direction, heating portions of only a bead of the glass ribbon to form compressive stress regions in the bead, scoring the glass ribbon to form a score line on which the glass ribbon is broken. The bead is heated at a position upstream from the score line. An apparatus for manufacturing a glass article includes a draw housing for forming a glass ribbon having a bead, a heating apparatus with a heat source for forming compressive stress regions in portions of only the bead of the glass ribbon, and a scoring apparatus that forms a score line on which the glass ribbon is broken to form the glass article. The heat source moves downstream simultaneously with the glass ribbon.
