Ultraflex dies without restrictor bars are used for product thickness ranges below 2mm (0.080”). Ultraflex dies with restrictor bars are used when product thicknesses range both below and above 2mm (0.080”), or for highly degradable materials.
When processors require larger lip gaps, a common choice is a die with a sliding upper lip. A sliding upper lip provides travel of up to 12.5mm (0.500”). This design is frequently used when product thickness is always above 2mm (0.080”), and materials are thermally stable. Nordson Extrusion Dies Industries' FastGap™ lip adjusting system and FastDeckle™ system are commonly included.
Gain the convenience of rapid online lip gap control with Nordson Extrusion Dies Industries' FastGap lip adjusting system. Prevent costly down-time for width changes with Nordson Extrusion Dies Industries' FastDeckle system.
For dedicated coextrusion applications with relatively expensive cap layers, the multi-manifold approach is commonly preferred over a single manifold die with a feedblock. Nordson Extrusion Dies Industries' accurate flow channel design uses less of a cap layer, providing a rapid return on investment.
