Abstract: A method for producing a permanently-magnetic part, made from a polymeric support material filled with magnetic filler materials on the basis of silicon caoutchouc, hot-vulcanized from at least one starting material, in which the at least one starting material of the silicon caoutchouc is mixed prior to vulcanization with 50 to 95% by weight of high energy ferrite particles of a density of 5.0 to 5.2 g/cm3 and an average particle size of 1.5 to 2.5 μm as the magnetic filler material and is homogenized. Subsequently, the homogenized mixture is introduced into a mold cavity by a temperature-regulated screw and is cross-linked by vulcanization in the mold cavity by the application of heat for forming the molding, wherein during cross-linking a static magnetic field is applied to the mold cavity and the magnetic filler materials are magnetized and aligned in the silicon caoutchouc being cross-linked.
