| Zusammenfassung: | A method of fabricating a piezo actuator is disclosed. The method includes forcing a blank against a mold to form a cylindrical casing having an open end and a closed end and rotating the cylindrical casing. The method also includes urging a die having a plurality of equally spaced protrusions into a surface of the cylindrical casing to form bellows in the cylindrical casing. The method further includes positioning a piezo element within the cylindrical casing. |
