Abstract:
1. A method for manufacturing a component of a magnetic actuator, wherein the component is one of a magnet armature, an internal pole or an external pole, the method comprising: manufacturing two different subcomponent groups of the component in a manufacturing sequence, a first subcomponent group including a plurality of sectors made of soft magnetic material and a second subcomponent group including a plurality of insulating separating webs; wherein one of: (i) manufacturing the first subcomponent group in a first step of the manufacturing sequence using an injection molding die such that the soft magnetic sectors of the first subcomponent group are held in the injection molding die with the aid of magnetic force, and subsequently injection-molding the insulating separating webs of the second subcomponent group between the soft magnetic sectors with the aid of a ceramic injection molding method; and (ii) manufacturing the second subcomponent group in a first step of the manufacturing sequence using the injection molding die such that the insulating separating webs of the second subcomponent group are held mechanically in the injection molding die, and subsequently injection-molding the soft magnetic sectors of the first subcomponent group between the insulating separating webs with the aid of a metal injection molding method.
