Abstract

A method for manufacturing a stator for an electric machine, having the following steps: inserting a cast body with a nozzle from a first side of the stator into the stator, inserting a cast counterbody from a second opposing side of the stator into the stator, casting the stator with thermoplastic, thermosetting plastic, or resin by means of the nozzle, curing the thermoplastic, thermosetting plastic, or resin, wherein following the curing a cast-on piece of the thermoplastic, thermosetting plastic, or resin is sheared off using a rotational movement of the cast body or cast counterbody.
