A multi-chamber pellet die system to improve and increase analysis pellet manufacturing capabilities by allowing for multiple pellets or biomaterial scaffolds to be fabricated simultaneously.

An object is extruded to have the form of a cage, the cage defined by spokes corresponding to several extrudate streams. The spokes bound a hollow interior and extend between opposed hub regions where the spokes are fused together. In manufacturing the objects, ceramic material is extruded through multiple dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extrusion to vary the position of extrudate streams exiting the dies.

An article comprising a) a die core having a plurality of flow paths adapted to flow extrudable material to a plurality of slots including wall slots and skin slots and around a plurality of pins so as to form a honeycomb structure from the extrudable material; and b) a mounting plate adapted to hold the die core in an extrusion system having an opening adapted to allow the extrudable material passed through the die core to exit, an outer portion adapted to mount and hold the die core in place, a flange about the periphery of the opening which seats the die core, an inner surface disposed to partially form the skin slots adapted to allow extrudable material to flow from the skin slots to form the skin of the honeycomb structure; and wherein the die core and mounting plate are comprised of different materials having different wear properties.

A method of making a die body configured to extrude a honeycomb body, the method comprising the step (I) of manufacturing a die body and the step (II) of predetermining an upstream slot width W1 of the die body such that the upstream slot width W1 is optimized while a root of each die pin includes a section modulus within a predetermined section modulus range. The method still further comprises the step (III) of predetermining a slot length L such that a pin stress is within a predetermined pin stress range.

A production method is provided. The production method comprises forming material by pressing or pulling ceramic material through a channel of an extrusion die, said channel being at least partly defined by the lateral surface area of at least one rotating die, and heat processing the formed material to form a ceramic product.

A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape.
