1. A die for extrusion of catalyst moldings, catalyst-support moldings or adsorbent moldings in flow direction of an extrudable composition from an entry side to a discharge side of the die comprising a shell and one or more channel-formers which are displacers of the extrudable composition and which extend in said flow direction of the extrudable composition, where said channel-formers which are displacers of said extrudable composition have been secured by way of one or more connecting webs directly to an interior side wall of the die, wherein the die is free from connections running at right angles from channel-formers to the interior side wall of the die and is free from cavities for receiving extrudable composition which extend at right angles to the flow direction of the extrudable composition, and wherein the channel-formers have been metal-printed.
