Six Sigma In Metallurgy

Amongst the many applications of Six Sigma in metal refining, the one in metal refining

stands out as one of the foremost areas of Application of Six Sigma tools & techniques. Met-Mex Penoles, world's largest refiner of Silver extensively uses simulation of the refining process along with DoE to cut down on the number of trial runs. This enables the company to work on Process Optimization and sacrifice a minimum of gold and silver during experimentation. While working with Silver and Gold it is costly to run pilot projects testing innovations in the manufacturing process. However, by simulating changes to the Process Design, Met-Mex Penholes is able to address lot of issues and questions without actually running trials of the process. Besides, a number of metallurgical plants across the world have successfully applied Process Control techniques including SPC. Some of the other examples of Lean Six Sigma Application in Metallurgy Industry are:

• Improving overall Quality of welding process by identifying & controlling critical input variables before welding, during welding and post welding.
  
• Improving the Quality (&Yield) of the Metal Finishing Processes
  
• Improving Powder Metallurgy Processing techniques
  
• Maximizing Productivity and reducing variability in Operations
