A method of making a two-component piston, the two-component piston comprising a piston cover as a first component and a piston body as a second component, the piston cover arranged adjacent to the piston body and configured to be moved relative to the piston body, the method comprising:
- forming the piston cover;
- and subsequently
- forming the piston body at the piston cover such that the piston body is non-releasably formed at the piston cover by a non-releasable connection present between the piston body and the piston cover, and the non-releasable connection is produced by a part of the piston body that is formed to extend through an attachment portion of the piston cover.
