Abstract

Wear and failure modes exhibited by narrow neck press and blow (NNPB) plungers in the glass container industry have been related to inappropriate material selection. Problems exist with substrate and coating materials which lead to machine down time, process instability and poor product quality. Previous attempts to improve the service life of NNPB plungers have not examined the process operating characteristics and demanding nature of the application. New substrate and coating materials have been utilized and an assessment of their suitability for this application examined. Initial results from plant trials with modified plungers suggest that improvements in operational performance are achievable. This application, and other components of the mould tooling set, may benefit from improvements which may increase tool life and reduce the problems which result from the application of lubricant dopes to glass contact surfaces.
