Methods of Extruding a Honeycomb Body |
摘要 |
Methods of extruding a honeycomb body with an extruder comprise the step of feeding batch material to the extruder, wherein the batch material comprises a ceramic or ceramic-forming material. The methods further include the step of rotating at least one mixing screw to cause the batch material to travel along a flow path defined by a barrel of the extruder. The methods further include the step of indexing a carriage to remove a first device from the flow path and introduce a second device into the flow path of the batch material. In one example, the pressure of the batch material changes less than about 25% as a result of indexing the carriage. In addition or alternatively, further methods include the step of reducing a decrease in temperature of the batch material resulting from the step of indexing. In further examples, the method includes the step of pre-filling a second honeycomb extrusion die held by the carriage with a plugging material. |
