Product catalog summary
Introduction
Nordson Corporation is a leading supplier of extrusion die and feedblock technology, offering custom-engineered flat extrusion dies and related components for various applications. The company emphasizes the importance of coextrusion, which combines multiple materials to achieve desired product properties such as gloss, toughness, and barrier capabilities.

Coextrusion Solutions
Nordson provides a range of coextrusion solutions, including:
  • EDI Multi-Manifold Coextrusion Dies
  • EDI Ultraflow™ Adjustable and Fixed Geometry Coextrusion Feedblocks
  • EDI Layer Multiplication Technology
  • Specialty and European Coextrusion Feedblock Designs
These solutions are designed to optimize material use, improve product quality, and enhance production efficiency.

EDI™ Coextrusion Technology
The EDI Ultraflow™ V Design features controllable linear valves for precise layer ratio changes, a split body design for easy cleaning, and optional layer multiplication technology. The adjustable geometry feedblocks allow for customizable entrance locations and stable layer ratios.

Specifications
  • Maximum Number of Layers: 13*
  • Maximum Number of Extruders: > 3
  • Layer Ratio Adjustability: Up to 45% without downtime
  • Layer Multiplication Technology: Available

Multi-Manifold Coextrusion Die Design
This design offers precise individual layer distribution, accommodating dissimilar viscosity materials and partial coverage requirements. It supports structures with skin layers of less than 10% and melt temperature differentials up to 50°F.

Layer Multiplication Technology (LMT)
Nordson's LMT allows for the multiplication of layers within a coextrusion structure, maintaining the same overall thickness and raw material usage. It enhances barrier properties and prolongs shelf life in food packaging applications.

European Coextrusion Feedblock Designs
These designs provide a compact and modular solution, adaptable to various polymer flow characteristics and end-product properties. They offer flexibility for high-end applications.

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 dissimilar...
