Extrusion Coating Die facilitates changes in product width.

EXTRUSION DIES INDUSTRIES    Chippewa Falls, WI 54729-1443
Nov 29, 2010 Available with external cooling option, EPC(TM) Die incorporates deckle system that can be adjusted to minimize formation of edge bead, which wastes polymer and substrate as it is trimmed from web. External deckle prevents leakage, while internal deckle has independently adjustable components that seal off ports of internal flow channel. To clean away carbonized polymer that causes die lines, operators can retract external and die-gap deckle components and insert brass scraper.

Slot Coating Die provides streak-free application of PSAs.

Mar 24, 2010 Available as stand-alone system or as component of completely integrated, computer-controlled coating station, Slot Die for coating continuous-web substrates accommodates line speeds up to 2,000 fpm and achieves coat weights as low as 0.5 mil. Die includes system for adjusting cross-direction coat weight profile and device that eliminates streaking and makes clear application of pressure sensitive adhesives possible.

XPS Foam Board Die System minimizes product changeover time.

EXTRUSION DIES INDUSTRIES    Chippewa Falls, WI 54729-1443
Feb 05, 2010 Designed for extruded polystyrene foam board, Die System enables on-the-fly product changeovers without stopping production line. System features adjustable full-manifold internal deckle inside flow channel of die and external edge restrictors that create final side dimensions on board as it emerges from forming box. Located between extruder and die, purge block makes it possible to carry out die maintenance while extruder is shut down but still full of polymer.

Flat Dies withstand exposure to HCl.

Extrusion Dies, Inc.    Chippewa Falls, WI 54729
Jul 20, 2009 Flat dies with DuraCoat(TM) coating withstand most attacks from corrosive hydrochloric acid (HCl) generated in course of extruding PVC. Coating forms thin film on steel surface of die that has no effect on features machined into flow surfaces. Solution is insolubile in most acids and bases, and also withstands burn-outs without damage.

Motorized Dual Deckle automates width changes.

Extrusion Dies, Inc.    Chippewa Falls, WI 54729
Aug 15, 2007 Featuring spring-loaded external segment, Motorized Dual Deckle minimizes or eliminates manual adjustment. It combines internal deckle, which blocks flow with blades from manifold to die lips, and external deckle, which seals off die gap from outside. AC motor drives external deckle and primary internal deckle as single unit, while smaller motor drives secondary internal deckle that fine-tunes flow at either end of die, minimizing formation of edge bead.

Flat Die System uses Dow's Layer Multiplier design.

Extrusion Dies, Inc.    Chippewa Falls, WI 54729
Aug 03, 2006 Integrating layer multiplier technology into custom-engineered system that includes die, feedblock, and other tooling components, Flat Die System distributes complex structure into finished extrudate. It produces films and coatings with greater number of layers than conventional coextrusions, yielding microlayer structures that optimize moisture and gas barrier, and encapsulate gels and un-melts. With greater number of layers, likelihood of breakage caused by pinholes in film is minimized.

Multi-Manifold Slot Dies help eliminate contamination.

Extrusion Dies, Inc.    Chippewa Falls, WI 54729
Nov 22, 2005 Suited for proximity coating of fluids onto web substrates, dual- and triple-manifold Ultracoat® dies replace multi-stage processes with single-pass coating. They enable converters to use single die to apply 2 or more coatings simultaneously, avoiding oxidation and contamination coatings can undergo between stages. Product is used in process that pre-meters coating fluid at constant rate and is fully enclosed to reduce issues with airborne emissions.
