Linking Process Capability Improvement to Carbon Reduction in SME Die Casting: A Case Study of Aluminum Alloy Components

High shrinkage-related defect rates in aluminum die casting reduce effective production capacity. They also create energy-intensive re-melting loops, which weaken production planning reliability and environmental performance. This study examines how Green Lean Six Sigma can stabilize a resource-constrained Small and Me...
