Six Sigma is an organized & systematic method for strategic process improvement that relies on statistical & scientific methods to reduce the defect rates and achieve significant quality upgradation. A case study is carried out for a foundry, where Six Sigma methodology is implemented for the defect reduction. The optimized parameters are considered to perform the practical run for the differen...

Abstract Logic gates are fundamental components of integrated circuits, and integration strategies involving multiple logic advanced materials have been developed to meet the development requirements high-density circuits. However, these still far from being widely applicable owing their incompatibility with modern silicon-based foundry lines. Here, we propose a silicon-foundry-line-based multi...

Introduction: During the past 30 years, the melting methods and associated molten metal-handling systems used by the U.S. foundry industry have changed significantly. During the same period, while ductile iron production has experienced continued growth, the quality of metallic scrap and other ironunit feed stocks has steadily deteriorated. The result: slag related melting problems have become ...

T. Lis, K. Nowacki, K. Łakomy Silesian University of Technology, Department of Production Engineering, Katowice, Poland In the European Union one of the most important activities is the recovery and recycling of waste including foundry waste. In the article waste arising from production of iron casting was presented. Selected physic-chemical properties of iron-bearing waste were defined. Opport...
