A Six Sigma project focused on reducing core and mold making total cost to produce precision sand cast parts is reviewed. The core-making, casting performance and environmental characteristics of the Cold Box technology are benchmarked and improved upon using Six Sigma methodology. Significant improvements include markedly enhanced productivity, reduced amine usage, improved worker environment, and reduction in tooling maintenance. In addition, the Six Sigma approach systematically ensures that multiple variables are measured and analyzed prior to implementation, control of the precision sand casting process, and provides a tool to compete aggressively in the global market place.
