Abstract
One aspect is for a method of manufacturing a magnetic coil for a magnetic actuator. A coil carrier is provided which comprises a tubular section and a collar which adjoins the tubular section, wherein the coil carrier is arranged for accommodating a coil winding. A die comprising a defined inner contour is provided which is adapted to the coil carrier. The coil carrier is inserted into the die, wherein the collar of the coil carrier rests on a seating surface of the die. The collar is punched with a punch, wherein a flange contour is formed at the collar the outline of which is defined by an inner contour of the die. The coil carrier is also at least sectionally potted or overmolded with a filler material, wherein the flange contour provides a barrier for the filler material. The disclosure further relates to a corresponding magnetic coil.
