Abstract
A multi-part extrusion die is disclosed which not only permits the formation of thin discharge slots down to about 0.003 or 0.002 inches, but also provides the ability to produce a die for forming a honeycomb article with different cell densities and web thicknesses in various sections. A plurality of individual die parts are each provided with discharge slots in a discharge face thereof of desired width and spacing, and then a plurality of such individual die parts are secured together in a desired alignment such that the discharge face of each of the plurality of die parts forms a continuous discharge face for the multi-part extrusion die.
