Nordson Announces Nine-Manifold Die
- Published: October 23, 2015
CHIPPEWA FALLS, WI | Nordson Corporation reports that an EDI nine-manifold flat die, said to be the first of its kind, has been successfully 
commissioned, producing nine-layer film from various resins. Company says this latest advance in coextrusion technology enables film processors—particularly those with high-throughput lines dedicated to a narrow range of products—to achieve tighter thickness tolerances for the individual layers in a multilayer structure.
The technology promises to reduce variation in individual layer thickness from the ±15% tolerance often encountered with comparably advanced feedblock systems to ±5%, says Sam G. Iuliano, chief technologist for Nordson EDI. “This greater accuracy achievable with multi-manifold dies enables processors to run thinner layers of the costly specialty materials often required for high-performance packaging films, while at the same time enhancing product quality and consistency.”
For the new nine-manifold die, the company designed additional fasteners outboard of the main die bodies (in the end plate assembly area) to ensure proper sealing. Also reports it will custom-design Ultracart rapid cleaning station for a customer’s specific multi-manifold die
The Autoflex automatic lip adjusting units on the die are modular and can be readily detached, allowing access to the die body fasteners. These systems are said to make disassembly and reassembly simpler for periodic cleaning and preventative maintenance of the die.
