Zusammenfassung:	A method for forming an extrusion die for producing honeycomb structures having hexagonal shaped cells is disclosed. A plurality of at least three plates are straight cut across the surface portion of each plate with desired angles to produce hexagonal shaped pins. The pins from each of the three plates are successively bonded to a die body or laminated carrier plate, with such orientation and positioning as to produce a die face with hexagonally shaped discharge slots.
