Learn moreAdvantages of EDI® Slot Die Coaters & Fluid Coating Systems
There are many reasons why customers choose EDI® slot die coating machines and fluid coating systems, here are just a few.
- Save time and reduce costs. Process improvements and improved efficiency lead to cost savings. Advanced precision means you save money on raw materials.
- Greater accuracy means higher quality end products. Our slot dies are manufactured using precision grinding and hand-lapping techniques to ensure precise tolerances and an exceptionally uniform slot gap.
- Customize your slot die coating machine for your fluids and application. Provide us with the fluid rheology for each fluid you use, and we will utilize our proprietary die manifold software to design a custom solution for you. Our slot dies can be custom-designed for solvent and water-based coating, slurries, paint, hard coating, UV-curable coatings, adhesives, and many more.
- Fixed and flexible systems are available. Choose fixed lip dies for improved coating consistency, and flexible lip dies for better control of coating process parameters.

EDI® Prodigi™ Slot Die
Benefits of Slot Die Coating vs. Roll Coating
Slot coating is a highly advantageous alternative to traditional roll coating, particularly in terms of cost savings and process improvements.
- Improve coating fluid yields with a pre-metered slot die system that applies all the coating fluid to the substrate via a positive displacement pump and slot die.
- Achieve coating property consistency with a closed slot coating system, designed to reduce contamination and emission of volatiles while maintaining consistent fluid properties throughout the entire production run.
- Boost end-product yields with a uniform coat weight produced by the slot die’s manifold geometry, which is designed to uniformly distribute the fluid based on its rheology.
- Increase production rates with a slot coating system, allowing for better control of the cross-web uniformity and capability to increase the percentage of solids, thus reducing drying time.
- Reduce downtime for product changeovers with a slot die designed for a large window of coating widths and thicknesses.
- Expand production capabilities with a multi-layer slot die designed to apply up to 3 fluids in one pass.
