Abstract: A manufacturing system includes a tape advancing through the manufacturing system and a station of the manufacturing system. The tape includes a first portion having grains of an inorganic material bound by an organic binder. The station of the manufacturing system receives the first portion of the tape and prepares the tape for sintering by chemically changing the organic binder and/or removing the organic binder from the first portion of the tape, leaving the grains of the inorganic material, to form a second portion of the tape and, at least in part, prepare the tape for sintering.

Abstract: A cooling apparatus for an extruder includes a supply line configured to receive bulk coolant from a supply circuit via an inlet. The supply line delivers supply coolant to the extruder along a flow path. A return line communicates expelled coolant from the extruder, and a circulation line connects the supply line to the return line. The circulation line supplies a recirculated portion of the expelled coolant to the supply line and mixes the bulk coolant with the recirculated portion of the expelled coolant forming the supply coolant. A bypass line connects the supply line to the return line, and a flow control valve connects one of the supply line and the return line to the bypass line. A proportion of the expelled coolant to the bulk coolant forming the supply coolant is adjusted by the flow control valve to control the temperature of the supply coolant.

Abstract: A system (100) and method to control rheology of ceramic pre-cursor batch during extrusion is described herein. An extrusion system (100) comprises an extruder (122) with an input port (144) configured to feed ceramic pre-cursor batch into a first section (120) of an extruder barrel and a discharge port configured to extrude a ceramic pre-cursor extrudate (172) out of the extruder barrel downstream of the input port (144). A liquid injector (210) is configured to inject liquid into the ceramic pre-cursor batch. A sensor (106) is configured to detect a rheology characteristic of the ceramic pre-cursor batch. A controller (108) is configured (i) to receive the rheology characteristic from the sensor (106), (ii) compare the rheology characteristic to a predetermined rheology value of the ceramic pre-cursor batch, and (iii) generate a command based on the comparison. A liquid regulator (110) is configured to receive the command and adjust liquid flow to the liquid injector (210) based on the command.
