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.

Abstract: A method of making a die body configured to extrude a honeycomb body, the method comprising the step (I) of manufacturing a die body and the step (II) of predetermining an upstream slot width W1 of the die body such that the upstream slot width W1 is optimized while a root of each die pin includes a section modulus within a predetermined section modulus range. The method still further comprises the step (III) of predetermining a slot length L such that a pin stress is within a predetermined pin stress range.
