The coating quality and the coating weight uniformity in the slot die are a function of die design and die geometry. Recent advances in understanding the fluid mechanics in the slot die have resulted in computer programs that help us design the die internals and lips to meet the specified requirements.

A review on viscocapillary models of pre-metered coating flows Abstract. Recent research results on viscocapillary models of various pre-metered coating flows such as curtain, slide, and slot coatings have been reviewed in this paper. Contact All Suppliers Coatings - copybook.com Curtain Coating - Curtain coating methods allow the flow of liquid to be continuous and ensure an even coating in a cross web direction. Curtain, slot and slide are all coating methods. The uncoated substrate is transported on a conveyor belt at a controlled speed. The liquid is deposited onto the substrate via a gap between two conveyors. Using pre-metered coatings you can produce thinner coats down to nanometers, produce more even layers, lower your costs of dyes and increase the speed of ...
