Solving V-buckle and Sag Issues
Who: Multi-site metal producer in Europe.
Product: Aluminum coated products.
Problem: This producer uses different cores for different calipers and experience sags and v-buckles in the aluminum, costing up to €30K per roll and damaging the aluminum.
Solution: We visited the producer’s sites and performed testing at our Core Competency Centre to optimise cores for each site.
Result: The customer avoided v buckle and sag issues, saving €30K per damaged roll as well as 5-10% cost savings on core spend through our optimisation project.
V-Buckle Cost Savings Generated
Who: Metal customer in Eastern Europe.
Problem: The customer required both outside diameter stiffness and sufficient wall thickness to prevent v-buckles when winding thin aluminum sheets.
Solution: Our core specification focused on outside diameter stiffness and wall thickness parameters.
Result: Our customer prevented further v-buckle issues and saved up to €30K per roll by not wasting damaged material.
