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 electric vehicle, including, a user compartment and a front section including a portion of a vehicle chassis, a crash absorbing member located in the front section and connected to the portion of the vehicle chassis, the crash absorbing member including a first extruded profile, preferably an aluminum profile, having a main extension direction in a transverse direction (y) of the vehicle, whereby the extrusion direction of the first extruded profile extends substantially in the transverse direction (y) of the vehicle, and wherein further the first extruded profile includes at least two cells (C1, C2) being defined by outer walls and at least one intermediate wall separating the at least two cells (C1, C2), wherein the at least one intermediate wall has a main extension direction in the transverse direction (y) and a second extension direction which extends substantially in a vertical direction (z).

A mounting bracket (50) comprises a non-planar structure shaped by bending one or more portions of a planar body, wherein the planar body comprises before it is formed into a planar body a two-dimensionally profiled load-path approximated lower-mass structure. The planar body may be a blank stamped from material sheet or a slice separated from a profiled material block. The two-dimensionally profiled planar body may be iteratively designed using load-path analysis taking account of functional regions and preserve regions. The bracket may be used as load support for wall and roof cladding installations that require a large number of support brackets.

A seat frame manufacturing method including: performing extrusion molding of a metal material to form a workpiece material, which has a closed section shape or a solid section shape in which a plate piece continuous in an extrusion direction protrudes in a protruding direction from a portion thereof; and performing press working, the press working including bending a part of the plate piece of the workpiece material in an out-of-plane direction of the plate piece, which is different from the protruding direction of the plate piece, to obtain a finished product.

The invention relates to a method for producing tailored sheet-metal strips, in which at least one sheet-metal strip having a substantially planar surface is integrally connected along its longitudinal edge to at least one further web-shaped semifinished product made of metal, wherein the at least one further web-shaped semifinished product differs from the at least one sheet-metal strip in terms of at least one of its properties, and wherein the at least one sheet-metal strip and the at least one further web-shaped semifinished product are fed continuously to at least one joining station, characterized in that a web-shaped semifinished product having a three-dimensional structure, a hollow profile and/or a multiplicity of recesses and/or holes in succession along its longitudinal edge is used as the at least one further web-shaped semifinished product which is fed to the joining station. An apparatus for carrying out the method is furthermore claimed.

Extruded cylinder liners and methods of forming the same are disclosed. The extruded engine cylinder liner may include a cylindrical body having a longitudinal axis and defining an inner surface and an outer surface. A plurality of spaced apart features may protrude from the outer surface and may extend in a direction oblique to the longitudinal axis. The method may include extruding a metal material through a die to form a cylindrical body defining an inner surface and an outer surface and a plurality of spaced apart features protruding from the outer surface. The die may be rotated about a longitudinal axis during at least a portion of the extruding step such that the features extend in a direction oblique to the longitudinal axis. The oblique features may allow parent casting material to enter channels therebetween and prevent the liner from moving in the vertical and horizontal directions.
