Apparatus And Method For Forming Skin On A Ceramic Body By Extrusion
摘要:
A honeycomb extrusion apparatus comprises a die body and a flow control device. The die body comprises an inlet end, an outlet end, a central axis, a first set of feedholes, a second set of feedholes, a set of central slots, and a set of outermost peripheral slots. The first set of feedholes extends from the inlet end to an interior interface portion of the die body. The second set of feedholes extends through the die body from the inlet end to the outlet end. The set of central slots extends from the outlet end to the interior interface portion of the die body. The set of outermost peripheral slots is disposed radially outwardly of the central slots. The interior interface portion of the die body is configured to allow flow of the batch material from the first set of feedholes to the central slots and to the outermost peripheral slots.
