Adjustable Geometry Coextrusion Feedblocks

This entirely new and highly effective method for layer combination and profiling has revolutionized the industry. Layers pass through precisely sculptured inserts that are housed in the Combining Spools. Fine adjusters allow these Combining Spools to be rotated to vary both the height and width of the tapered exit geometry for each layer, providing robust on-line control of layer uniformity in the final product. In addition, optional thermal profiling capability is possible through a series of miniature heaters that may be installed downstream of the combining point.

Ultracoat II Precision Slot Die Coating Heads

For applying low-viscosity or wet coating materials, Ultracoat dies provide greater precision than roll-coating systems. Since all of the coating material is applied to the substrate in a metered fashion, significant savings in raw materials can be realized. EDI's dedicated clean room for optimum grinding ensures die flatness, so that coat weight uniformity can be maximized. Ultracoat II dies incorporate a flexible lip feature to refine coat weight distribution across the substrate and are available with manual or automatic lip adjusting mechanisms. A variable offset between the wet-side and dry-side lip faces can be achieved utilizing supplied shims. Application-specific lip face designs are available.
