The 7Epsilon initiative, led by Swansea University, brought together a consortium of European foundry experts, process engineers, trade associations, universities and institutions to develop a philosophy that would go beyond Six Sigma thinking on knowledge management and continual process improvement. Since 2012, over 175 foundry process engineers in Europe, the U.S., and India have been introduced or trained in the technique. Read the results of their insights for a gray iron foundry that implemented an energy optimization program following the 7Epsilon principles.
