Extrusion Dies Industries
LLC (EDI) has announced the availability of a new slot die for coating
continuous-web substrates that provides consistent, streak-free application of
pressure-sensitive adhesives (PSAs), achieving higher line speeds and greater
accuracy than conventional roll coating, with less environmental impact.
EDI developed the die
specifically for PSAs. While roll-coating speeds for hot-melt applications
usually do not exceed 1200 feet/min. (365 meters/min.), the new die developed
by EDI accommodates line speeds up to 2,000 feet/min. (610 meters/min.) and
achieves coat weights as low as 0.5 mil (0.0127 mm) - well below the
conventional lower limit for hot melts of 1.0 mil (0.025 mm).
In addition to availability as a
stand-alone system, the new EDI die can be supplied as part of a completely
integrated, computer-controlled coating station incorporating melt delivery
systems from ITW Dynatec and slot die equipment from EDI.
