Case Study: REXAM Beverage Can Group reduces coating variation and saves €35,000 with Minitab Statistical Software

Capturing Quality in a Can

REXAM Beverage Can Group, a global leader in metal beverage can manufacturing, faced a challenge with variation in the internal coating weight of cans produced on two high-volume lines. The company turned to Minitab statistical software to analyze the issue and support its Six Sigma improvement project.

Using Minitab, REXAM validated its measurement system, analyzed process capability, ran statistical tests, and used design of experiments to optimize key variables such as application duration, angle, pressure, and nozzle distance. The improvements reduced lacquer use by 5 mg per can and generated annual savings of about €35,000, while maintaining product quality and sustaining the gains over time.
