Abstract: The invention relates to a method for producing a torsional vibration damper housing, especially the housing for a viscosity torsional vibration damper, whereby the damper housing is manufactured from an existing plate circular blank and the shaping of the damper housing occurs in an impact extrusion machine during a non-cutting impact extrusion shaping method. In successive impact extrusion shaping steps, all parts of the damper housing protruding from the plane of the plate circular blank, which forms the housing rear wall, are impact extruded while reducing the wall thickness of said parts to form a one-piece damper housing. Said damper housing is structured such that the area of the fastening flange has the largest thickness.

Abstract: A method of fabricating a circular-shaped metal structure, includes the steps of (a) rotating a pipe around an axis thereof, the pipe being composed of a plastic-workable metal, and (b) applying drawing to an outer wall of the pipe with the pipe being kept rotated, to reduce a wall thickness of the pipe and lengthen a wall of the pipe. A resultant circular-shaped metal structure fabricated by the method could have a thickness equal to or smaller than 0.09 mm.

Abstract: A method of preparing a sheet of material for bending along a bend line comprising the step of forming of at least one displacement in the thickness direction of the sheet of material with a portion of the periphery of the displacement closest to the bend line providing an edge and opposed face configured in position to produce edge-to-face engagement of the sheet on opposite sides of the periphery during bending. The forming step is preferably accomplished using one of a stamping process, a punching process, a roll-forming process and an embossing process. A sheet of material suitable for bending using the process also is disclosed, as are the use of coatings, shin guards and displacing the area of the sheet between bending inducing slits.
