EDI® Coextrusion Feedblock Technology

for exceptional end product performance

Coextrusion technology has evolved dramatically in the last few years, with Nordson Polymer Processing Systems leading the way. Our versatile coextrusion feedblocks have been developed utilizing over 50 years of polymer processing experience. Our investment in cutting-edge research and co-extruder technology keeps us at the forefront of the polymer processing and extrusion world.

 

When you browse our world-class range of feedblocks, you¡¯ll find features designed for dedicated structures, optimal layering sequences, the creation of flexible packaging, and more. We offer a range of coextrusion feedblocks to ensure we have the right technology available to elevate polymer processing for a wide range of materials and applications. In fact, we have coextrusion feedblocks available for any product that might be created by our extrusion dies that needs multiple layers or multiple resins. 

All our coextrusion feedblocks are EDI? products. Our innovative coextrusion technology increases the speed of your process, reduces downtime for maintenance and cleaning, and provides a precise and uniform final product. Our coextrusion feedblocks are particularly well-known for ensuring precise layer-to-layer ratios for multilayer extrusion. Our co-extruder technology ensures that when the polymer flows through the feedblock it's the correct structure and the right ratio compared to the next layer. Consistency is key throughout the width of each layer, and with EDI?, you can ensure accuracy.

 

Choosing the right coextrusion feedblock for your unique application is key. Our polymer processing experts are here to make it easy. We welcome you to contact us for a free consultation, to find the right coextrusion technology for you.

FAQs


  • Q: What are the key functions of a coextrusion feedblock?
    A:  A feedblock enables you to combine multiple polymer melts, creating layers of molten polymer. Feedblocks are essential where multiple polymers are used to create an end product, for example, if your product utilizes one polymer on the outside and another within. Whether you need a multi-layer structure inside of your product due to its protective or performance properties or to reduce costs, coextrusion feedblocks enable you to layer polymers with precision. 
  • Q: Where do coextrusion feedblocks fit in the extrusion process?

    A: Your coextrusion feedblock should be utilized before your polymer enters a single manifold die. 

  • Q: What is the difference between fixed and adjustable geometry feedblocks?

    A: Fixed geometry feedblocks are great for consistent use with the same layer-to-layer polymer ratio and structure, while adjustable geometry feedblocks enable efficiency if your processes change often. Both designs offer the ability to adjust, but you can easily change layer ratios without stopping production when you choose an adjustable design.

  • Q: Should I choose a feedblock or multi-manifold die?

    A: A coextrusion feedblock enables you to combine molten polymers before your product enters a single manifold die. A multi-manifold die enables the same process within the die itself, with the support of a distribution block.  Many of our extrusion dies can be used as multi-manifold solutions. Please contact us to discuss your unique application and find the right coextrusion solution for you. 

  • Q: What should I look for in a high-quality coextrusion feedblock?

    A: The answer depends on what’s important to you and your manufacturing process, but it’s always important to choose a coextrusion feedblock that enables a high-quality end-product. The EDI® brand is known for consistency, longevity, and creating accurate layer to layer ratios.
