A process for forming extruded products using a device having a scroll face configured to apply a rotational shearing force and an axial extrusion force to the same preselected location on material wherein a combination of the rotational shearing force and the axial extrusion force upon the same location cause a portion of the material to plasticize, flow and recombine in desired configurations. This process provides for a significant number of advantages and industrial applications, including but not limited to extruding tubes used for vehicle components with 50 to 100 percent greater ductility and energy absorption over conventional extrusion technologies, while dramatically reducing manufacturing costs.

An apparatus for extruding a material, the apparatus comprising: a block which includes two or more extrusion containers composed of heat resisting material, the containers being arranged to receive billets of the extruding material; a die set arranged downstream of the block including the two or more extrusion containers; and one or more rams, wherein the one or more rams are aligned with the axes of the extrusion containers and are arranged to push the billets of material through the extrusion containers into the die set; wherein the die set includes an upper die including two or more extrusion channels for extruding material from each of the extrusion containers, and a lower die incorporating a welding chamber, wherein two or more extruded billets from each of the extrusion channels are welded together and passed out through the exit of the die set.

An alloy for cladding cast iron is disclosed. The alloy may include on a weight basis, about 6.2% to about 9.3% of chromium (Cr), about 3.0% to about 4.5% of iron (Fe), about 1.4% to about 2.15% of silicon (Si), about 0.5% to about 0.8% of boron (B), about 0.1% of carbon (C), and a balance of nickel (Ni) and incidental impurities.

A raw material of aluminum base alloy is extruded and formed by using a forming pattern comprising an upper pattern having plural through-holes for supplying the raw material into diaphragms of equal angles on the circumference and circular cylindrical protrusions positioned in the center of plural through-holes so as to be surrounded by plural through-holes at the exit side of the through-holes, and a lower pattern positioned in the concave portions commonly penetrating at the exit of the plural through-holes of the upper pattern, having through-holes for inserting the protrusions of circular circumference of the upper pattern by providing a tube forming gap, positioned in the center of concave portions of the concave portions in the circular columnar shape of the upper pattern.

Systems, devices, and methods are described for extruding materials. In certain embodiments, one or more hollow billets are loaded onto an elongate mandrel bar and transported along the mandrel bar to a rotating die. The billets are transported through fluid clamps, which engage the mandrel bar and provide cooling fluid to the mandrel bar tip, and through mandrel grips, which engage the mandrel bar and prevent the mandrel bar from rotating. One or more press-rams advance the billets through a centering insert and into the rotating die. A quench assembly is provided at an extrusion end of the extrusion press to quench the extruded material. A programmable logic controller may be provided to control, at least in part, operations of the extrusion press system.

[Problem] To present a small-diameter magnesium base alloy tube and its manufacturing method of long length, high dimensional precision, and excellent mechanical properties.

[Solving Means] A raw material 1 of aluminum base alloy is extruded and formed by using a forming pattern comprising an upper pattern 2 having plural through-holes 21 for supplying the raw material into diaphragms of equal angles on the circumference and circular cylindrical protrusions 22 positioned in the center of plural through-holes 21 so as to be surrounded by plural through-holes 21 at the exit side of the through-holes 21, and a lower pattern 3 positioned in the concave portions commonly penetrating at the exit of the plural through-holes 21 of the upper pattern 2, having through-holes 32 for inserting the protrusions of circular circumference of the upper pattern by providing a tube forming gap, positioned in the center of concave portions 31 of the concave portions 31 in the circular columnar shape of the upper pattern 2.

A method of handling components for a sheet extrusion system including the steps of: obtaining a carriage configured to support different components each making up a part of a sheet extrusion system; placing a first of the different components in a supported staging position on the carriage; and performing an operation on the first of the different components in the supported staging position to at least one of: a) transport the first of the different components; b) perform a maintenance step on the first of the different components; c) repair the first of the different components; or d) set the first of the different components up for installation. The method further includes the steps of: separating the first of the different components from the supported staging position on the carriage; and reconfiguring the carriage to maintain a second of the different components, that is different in configuration than the first of the different components, in a supported staging position on the carriage.
