Description – What It Does
The Ultraflex R-75 is a 48″ sheet extrusion die engineered to transform molten thermoplastics into flat sheet with excellent gauge control and uniform melt distribution. By combining a flexible lip design with a patented internal restrictor bar, the die ensures consistent quality across the full sheet width.
It is designed for medium-thickness sheet extrusion and has been proven in applications requiring ¼″ sheet products.
