PRESS RELEASE
CHIPPEWA FALLS, WI—Extrusion Dies Industries has been granted a patent for a flat die design that is said to reduce downtime for lip adjustment required with each product run, enhance gauge profiles, and yield a uniform layer structure in coextrusion. The Contour Die has a unique tapered shaper: thicker in the center, where the bending force is greater, than at the ends. This design enables EDI to retain the triangle-shaped "coat hanger" manifold that is widely used in the industry because it promotes a streamlined flow of molten polymer through the die.
