Abstract
An extrusion system () according to certain aspects includes at least one infrared emitting device () arranged in a generally cylindrical shape with a hollow interior. The at least one infrared emitting device () is positioned downstream of an outlet of an extrusion die () to irradiate a perimeter of wet extrudate material in a uniform manner to form stiffened wet extrudate material () before such material is received by an extrudate support channel (). The at least one infrared emitting device () generally uniformly stiffens the skin of the wet extrudate material () 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.
