This paper outlines the properties required of narrow neck press and blow plungers. Typical characteristics of those materials most commonly used are discussed, and identifying wear modes unique within the container forming equipment are discussed. The potential for improvement in plunger performance to reduce ware defects, machine downtime, plunger maintenance and their associated costs is highlighted.
