A method for fabricating a non-planar magnet includes extruding a precursor material including neodymium iron boron crystalline grains into an original anisotropic neodymium iron boron permanent magnet having an original shape, wherein the original anisotropic neodymium iron boron permanent magnet has at least about 90 percent neodymium iron boron magnetic material by volume. The original anisotropic neodymium iron boron permanent magnet is heated to a deformation temperature. The original anisotropic neodymium iron boron permanent magnet is deformed into a reshaped anisotropic neodymium iron boron permanent magnet having a second shape substantially different from the original shape using heated tooling to apply a deformation load to the original anisotropic neodymium iron boron permanent magnet. The original anisotropic neodymium iron boron permanent magnet and the reshaped anisotropic neodymium iron boron permanent magnet each have respective magnetic moments substantially aligned with a respective local surface normal corresponding to the respective magnetic moment.

A method for manufacturing a motor vehicle structural component from an extruded multichamber hollow profile. The method includes providing an extruded profile with at least two precursor hollow chambers which are separated from one another by an inner wall, wherein in at least one outer wall of at least one precursor hollow chamber in cross-section perpendicularly to a longitudinal extent of the extruded profile has a region with non-linear course. The extruded profile is formed in at least one of its end regions into the motor vehicle structural component, wherein at least the region with non-linear course of the at least one outer wall of the at least one precursor hollow chamber, with non-linear course in cross-section, is at least partially straightened, with a change in cross-section of the respective precursor hollow chamber into the cross-section of the corresponding hollow chamber of the motor vehicle structural component.

The method further includes unfurling the wall to form a sheet precursor. The sheet precursor has a first thickness and a first transverse dimension. The method further includes rolling the sheet precursor along a rolling axis to form the metal sheet. The metal sheet has a second thickness perpendicular to the rolling axis. The second thickness is less than the first thickness. The second transverse dimension is parallel to the rolling axis. The second transverse dimension is greater than the first transverse dimension. In certain aspects, the metal includes lithium and the metal sheet is a lithium metal electrode.

Methods of manufacturing a door frame subassembly for an electronic display assembly and related systems and apparatuses are disclosed. A material is extruded to form a frame. The material is bent into a rectangular shape with rounded corners to define an opening. Notches may be formed in the frame to facilitate the bending. A remaining gap in the material is joined, such as by a bracket at a lower portion of the opening to secure the frame to itself.
