The invention is directed to a machine for compacting agricultural fibrous matter into a board, comprising a hopper for receiving the agricultural fibrous matter; an extruder comprising an extrusion passage downstream of the hopper; and a ram configured for moving in a reciprocal manner along the extrusion passage; wherein the extrusion passage further comprises a movable wall configured for moving between a feed position, opening the extrusion passage to the hopper, and an extrusion position, closing the extrusion passage.

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.

An extrusion press including a ram having a ram body configured for movement along a ram axis, and a compaction container defining a compaction compartment and having a compaction container axis. The compaction container is rotatable between a first orientation wherein the compaction container axis is not aligned with the ram axis and a second orientation wherein the compaction container axis is aligned with the ram axis such that the ram body is movable into the compaction compartment.

The invention relates to a method for coaxially extruding an extruded product. Hereby, an extruding device comprises the following: a receiver (7); a first receiver bore (5) which is formed in the receiver (7) and in which a first punch (10) is arranged; a second receiver bore (6) which is formed in the receiver (7) inside the first receiver bore (5) and coaxially therewith and in which a second punch (11) is arranged; and a mold (15) having a mold cavity (14) which is connected to the first and the second receiver bore (5, 6). In the method, the following is provided: arranging a first material billet (8) of a first material (2) in the first receiver bore (5); arranging a second material billet (9) of a second material (3) in the second receiver bore (6); and extruding an extruded product (1) in which the first and the second material (2, 3) are connected in a form-fitting and integrally bonded manner. The extrusion comprises: advancing the first punch (10) in the first receiver bore (5) in such a manner that the first material (2) is pressed into the mold cavity (14) of the mold (15) and thereby shaped; advancing the second punch (11) in the second receiver bore (6) in such a manner that the second material (3) is pressed into the mold cavity (14) of the mold (15) and thereby shaped, the second punch (11) being displaced coaxially with the first punch (10); and connecting the first and the second material in an integrally bonded and form-fitting manner to form an extruded product (1) in the mold (15) in such a manner that the first material (2) surrounds the second material (3) in the extruded product (1). The invention also relates to a device for coaxially extruding an extruded product.
