Abstract
A method for manufacturing a solenoid-armature ram composite and a corresponding solenoid-armature ram composite for a linear actuator which has a stator with a coil that can be fed with electrical current for producing an electromagnetic field and a single-part or multi-part solenoid armature movable along a longitudinal axis of the coil and a ram connected with the solenoid armature, provides that the solenoid armature surrounds the ram in a ring shape and a gap between the ram and the solenoid armature is cast with a casting material.
