Methods of creating a hook for a bike rack. The methods include the steps of providing a planar metal material, cutting a two-dimensional shape from the planar metal material where the two-dimensional shape defines a hook precursor, forming the hook precursor into a three-dimensional hook where the three-dimensional hook includes a hook face, and adding a protective layer to the hook face. In some examples, the methods include processing the three dimensional hook to remove sharp edges, cutting a mounting point into the hook precursor, cutting a bevel on an edge of the hook precursor to define a beveled edge, and/or cutting a curve on an edge of the hook precursor to define a rounded edge.

The disclosure relates to a method for material processing of a two-dimensional sheet like material. The method comprises: obtaining information related to a desired design of a three dimensional object; obtaining information related to material characteristics of the sheet like material; defining a primary surface and a secondary surface of the desired design; and defining a geometrical relationship between said primary surface and secondary surface, wherein the secondary surface is a reflection of the primary surface in a two dimensional plane, and wherein when said primary surface is concave said secondary surface is convex, or when said primary surface is convex said secondary surface is concave; and providing a digital instruction for a fully developed spreading and subsequent folding of a two dimensional sheet into the obtained desired design, wherein said digital instruction is based on the defined primary and secondary surfaces, respectively, and said obtained material characteristics.

Presented are metalworking systems for forming metallic workpieces, methods for making such workpieces and methods for operating such systems, and battery cell tabs bent by a multistage plunger press. A metalworking system includes a plunger fixture that mounts adjacent metallic workpieces, and a plunger head movably mounted to the plunger fixture to move between activated and deactivated positions. A first row of plunger fingers is mounted to the plunger head and moves in one direction to press against and bend one metallic workpiece a predefined bend angle. Likewise, a second row of plunger fingers is mounted to the plunger head and moves in an opposite direction to press against and bend another metallic workpiece another predefined bend angle. The plunger head then moves to the activated position, in tandem with the plunger fingers bending the metallic workpieces, to cause the plunger fingers to bend the workpieces additional respective bend angles.

A formed body 1 includes a first flange 3, a body portion 100 (a first vertical wall portion 4, a top plate portion 5, a second vertical wall portion 6), and a second flange 7, and the formed body 1 is made of steel having tensile strength of 440 MPa or more. The first flange 3 extends toward the second flange 7 from an edge portion of the first vertical wall portion 4. The first flange 3 and the body portion 100 curve so as to conform to each other as viewed from the direction orthogonal to the top plate portion 5.

The present disclosure relates to a mesh container and a method of making a mesh container that has a first and a second set of opposing side panels, a bottom panel, and a rim directed outwards from the upper edges of the side panels. At least two adjacent sides panels of the container and portion of the rim directed outwardly from the upper edge of the side panels are made from a sheet metal precursor with least one perforated and a stretched portion and unstretched metal portion. The precursor is folded so that the unstretched metal portion joins the two side panels and is bent to form the rim. A notch is cut from the edge of the unstretched metal portion where it is bent at the corner formed by the two side panels.
