Intermediate inspection of the substrate for DuPont's Corfam poromeric shoe upper material is one of the many quality control points in the manufacturing process at Old Hickory, Tennessee. At this stage, the substrate is inspected visually for thickness and uniformity. Research and development of Corfam required 200 man years, with much of the effort devoted to perfecting the final product.
Corfam poromeric shoe upper material is checked foot by foot for uniformity of texture, color and thickness at the DuPont Company's Old Hickory, Tennessee plant. Corfam is the result of 200 man hours of research and testing at the chemical company.
Continuous roll of Corfam poromeric shoe material is inspected at DuPont's pilot plant for the man made upper material in Newburg, New York.
