Slot Die Coating and its applications

Recently customers requirements have increased for high precision, uniform layers of 4µ to 400µ for ceramic green sheet and Lithium batteries. Our Slot Die system has been engineered to address this requirement. Easy operation and coating accuracy is obtainable with dies for widths of 100mm or 1000mm. Drying becomes a very important consideration with these thicknesses. Special arch type idler supported dryers and flotation systems with patented, high efficiency air bars can be provided.

4 to 400 microns wet thickness, with occasional experiences to 2 micron and 1 mm.
Coating onto webs from 8 micron (30 gauge) PET to 350 micron (1400 ga.) PET, foils, paper, glass felts, cloth, Kapton®, other specialty films, PP, PE, etc.
This listing is only a sampling of present applications. New applications are ALWAYS welcome.
Recent new internal flow design to greatly expand the range of viscosity of a single slot die, without adjustment "bolts", that achieved +/- 1.3 pct profile on 120 microns dry. Patent is applied for on this new design element.
