EDI™ Coextrusion Technology EDI Adjustable Geometry Feedblock Design Nordson’s EDI Adjustable Geometry Feedblocks combine polymers in a parallel path manner, achieving optimal layer ratio stability throughout the structure. This flexible design allows for entrance locations to be customized, based on your line design and layout. EDI Ultraflow™ V Design Controllable linear valves allow for highly precise layer ratio changes Split body design minimizes the physical space requirement and allows for easy cleaning “On-the-fly” layer ratio adjustability increases uptime and precision, while...

EDI™ Coextrusion Technology EDI Multi-Manifold Coextrusion Dies Nordson’s EDI multi-manifold coextrusion dies utilize the “naked edge” or partial coverage feature, allowing for reduced trim and increased material savings. Coextrusion is accomplished when layers are spread and thinned prior to be combined into a multi-layer structure. EDI Multi-Manifold Coextrusion Die Design The multi-manifold approach is the most precise form of coextrusion technology available Improved product quality is possible with precise individual layer distribution. Optimized manifolds are designed to accommodate...
