Dr. Sam Ramrattan, Professor in the Department of Engineering Design, Manufacturing and Manufacturing Systems at Western Michigan University, will be giving an update of the Qualifications to Predict Performance in Chemically Bonded Sands.

Chemically bonded sand cores and molds are an important part of metal casting technology, and their interaction with metal at the mold-metal interface is of great interest.  Recently the AFS has moved to adopt several new chemically bonded sand tests using a disc-shaped specimen as standards.  These tests have proven to be an efficient laboratory testing technique to determine chemically bonded sand properties.  Casting trial techniques using disc-shaped specimens provide insight to foundry quality control.  The casting trial technique provides new opportunities for data analysis and deeper system understanding.

Dr. Sam received his Bachelors & Masters from the University of Wisconsin-Stout, and Ph.D. & Post Doc. from Iowa State University.  His area of specialization is materials & processes emphasizing casting processes.  He is a member of the 4F and 4H Research Committees at AFS, Technical Adviser to the Western Michigan University Student Chapters of AFS and NADCA, and a Key Professor for the Foundry Educational Foundation (FEF).  He was a recipient of the AFS Scientific Merit Award, the British Foundry Medal and several outstanding teaching awards. He has published more than two hundred papers and presented in sixteen different countries. Dr. Sam has taught at the University of Wisconsin-Stout, Iowa State University, and University of Technology Malaysia.
