Michael Sepe has worked in the plastics industry since 1975 in a variety of roles involving both manufacturing and research and development. He is an independent consultant based in Arizona with clients throughout North America. He assists clients with material selection, designing for manufacturability, process optimization, troubleshooting, and failure analysis.

From 1994-1999 he taught the injection molding apprenticeship program at Waukesha County Technical College where he re-designed the curriculum and authored a new text for the course. He has presented over 25 ANTEC papers and has written several book chapters on the testing of plastic materials. He authors a monthly column for Injection Molding Magazine titled “The Materials Analyst” on the practical aspects of using testing techniques to solve manufacturing problems. He teaches a variety of short courses for the University of Wisconsin and Penn State - Erie and gives in-plant seminars to designers and engineers on material selection, processing, and troubleshooting.
