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.

A hollow preform impact extruded from a metal billet to produce a progressing wall at a transition wall thickness. An axially forward portion of the progressing wall is ironed by extrusion past an extrusion point to form a sidewall portion of a lesser thickness. Extruding is stopped while some of the billet remains to form the closed bottom end. The preform has a bottom portion, a sidewall portion and a transition wall portion extending between the bottom portion and the sidewall portion. The transition wall portion is thicker than the sidewall portion and can be formed into at least part of the rim of an expansion shaped container. An impact extrusion punch has a central axis, an axially forward, impact surface for impacting metal to be extruded, a transition region for directing material displaced by the impact surface and a rear extrusion point for ironing material extruded past the transition region.

Certain exemplary embodiments can provide a manufacturing method, process, machine, and/or system for continuously consolidating granular materials, creating new alloys and/or composites, and/or modifying and/or refining material microstructure, by using plastic deformation of feedstock(s) provided in various structural forms. Materials produced during this process can be fabricated directly and/or in forms such as, e.g., wires, rods, tubes, sheets, plate and/or channels, etc.

A friction stir processing system can include a rotatable die assembly. The rotatable die assembly can include a die body and a plurality of die segments. The die body includes a die base and a die stem. The die stem extends axially from the die base, the die stem defines an extrusion cavity, and the die body is formed from a first material. The plurality of die stems are coupled to the die stem. The plurality of die segments are disposed around the extrusion cavity to collectively form a die surface opposite to the die base. The plurality of die segments are formed from a different material than the die body.

In the context of a forming method for producing a helical toothing of a cylindrical workpiece by extrusion, a relative movement of a forming tool and of a workpiece blank carried out in a peripheral direction of the forming tool and of the workpiece blank is superimposed on an axial forming movement of the forming tool and of the workpiece blank. Due to a forming relative movement of the forming tool and of the workpiece blank resulting from the mutual superimposition of the axial forming movement and the forming movement in the peripheral direction, the helical toothing of the workpiece is produced on the workpiece blank, in that the forming tool engages, with a shaping helical toothing, in the workpiece blank during the resulting forming relative movement. A forming machine is designed to carry out the aforementioned method.
