Abstract: A method for manufacturing a product from a flexibly rolled strip material includes the steps of: providing a strip material made from sheet steel; flexibly rolling the strip material such that a variable thickness is produced along the length of the strip material; electrolytically coating the strip material with a metallic coating material containing at least 93% of zinc by mass after the flexible rolling; heat treating at temperature above 350° C. and below a solidus line of the coating material after the electrolytic coating; working a blank from the flexibly rolled strip material; and hot forming the blank.

Abstract: A hardened formed part is manufactured with the steps: producing a blank from a hardenable strip material; heating of the blank to an austenitization temperature; forming and hardening of the blank to a hardened formed part; cleaning the hardened formed part; coating the hardened formed part with a metallic coating in an dipping bath with an electrolyte solution, wherein during the coating process, at least one auxiliary element is used in the dipping bath, such, that the deposition of the coating is partially influenced. A plant is used for manufacturing a hardened formed part.

Abstract: A product is made from a rolled strip material with the steps: rolling of a strip material from a sheet metal; working of a blank out of the rolled strip material; forming of the blank to a formed part; cleaning the formed part such that an amount of maximal 0.7 ppm of diffusible hydrogen is introduced into the formed part by cleaning, and coating the formed part with a metal coating material for producing a corrosion protection coating, wherein the step of coating is carried out in an immersion bath with an electrolyte solution, wherein between the formed part and the electrolyte solution a flow is generated.

Abstract: The invention relates to a method for manufacturing a product from a flexibly rolled strip material comprising the steps: providing a strip material made from sheet steel, flexible rolling of the strip material, wherein a variable thickness is produced along the length of the strip material, electrolytic coating with a metallic coating material, which contains at least 93% of zinc, wherein the electrolytic coating is carried out after the flexible rolling, heat treatment at temperatures above 350° C. and below a solidus line of the coating material, wherein the heat treatment is carried out after the electrolytic coating, working a blank from the flexibly rolled strip material and cold or hot forming of the blank.

Abstract: A band spring including fiber composite material and extending in an undulating way, wherein a spring band can be provided to meander in the form of one single wave train composed of reversal regions and intermediate portions around a longitudinal center line L which can substantially correspond to the direction of force introduction K, and wherein, there can be provided an increased resistance moment of the spring band in the reversal regions of the wave train.

Abstract: A spring plate for a valve spring of an internal combustion engine, which spring plate can be connected directly to the valve stem of a charge changing valve while engaging an annular groove in the valve stem. An annular disc is arranged on the valve spring and two supporting tongues which are directed radially inwardly from the annular disc and whose inner ends, in a plan view of the spring plate, comprise recesses for engaging an annular groove.
