One or more hollow billets are loaded onto an elongate mandrel bar for extrusion. The billets are 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 bumper cross member for a motor vehicle is produced from an extruded hollow profile and has a front side forming an impact side, a rear side in opposition to the front side, end zones configured for connection to the motor vehicle, a central zone extending between the end zones and bent toward the impact side, and top and bottom sides connecting the rear side with the front side. Each of the top and bottom sides has a projecting flange which is separated from the rear side by a separation cut configured to end shy of the end zones so that the flanges are connected with the bumper cross member in the end zones.

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.

The specification discloses a nonferrous extrusion system and process providing improved transfer of extrusions from the runout table to the cooling table. The runout table includes interleaved runout rollers and transfer rollers that are vertically shiftable with respect to one another. The transfer rollers additionally are horizontally shiftable between the runout table and the cooling table. The runout table receives extrusions in a longitudinal direction. The vertical and horizontal shifting of the rollers is controlled to transfer the extrusions from the runout table to the cooling table.
