Abstract
A novel multi-layer polymer coated steel has been developed and is being considered for container applications. This material presents an interesting extension to previous research on polymer laminated steel in ironing, and this paper presents a preliminary evaluation of the new material. A design-of-experiments matrix was prepared using the commercial software package Stat-Ease, and involved varying the die angle, speed, reduction in thickness and tooling temperature. Formability data has been obtained both through experimentation and theoretical modelling with upper bound methods. The three-layered polymer coated steel can result in a material with high ironability.
