The Penn College Plastics Innovation & Resource Center’s 14th annual Extrusion Seminar and Hands-On Workshop, led by experts Chris Rauwendaal, president of Rauwendaal Extrusion Engineering Inc., and the college's own Kirk M. Cantor, professor of plastics technology, attracted plastics-industry professionals from not only across the United States, but abroad as well. In the five-day workshop that ends Thursday, Rauwendaal presents course topics and Cantor (joined by PIRC staff, Penn College plastics technology faculty and students) leads participants in hands-on training in the college’s plastics and polymer technology labs.
