Abstract (en)
[origin: WO2022058461A2] The invention relates to a method for producing three-dimensional magnetic shields having sufficient permeability from unannealed, soft-annealed or magnetically annealed magnetically soft metal sheets, wherein the metal sheet is cold formed into the three-dimensional component either in a one-stage or multi-stage process, subsequently subjected to (magnetic) annealing in order to increase permeability, and then transferred to a forming tool in which it is held and/or pressed in a tool in the hot state or at room temperature, which tool has the target contour of the component and is shape-corrected or calibrated by the tool as applicable and is left to cool in the tool, or a sheet is heated for the purposes of forming and increasing permeability and then formed to the target geometry and held in a hot forming tool and left to cool in the tool, or the three-dimensional component is produced by additive manufacturing and subsequently subjected to (magnetic) annealing in order to increase permeability. The invention also relates to a shielding apparatus.
