Slot coating is commonly used in the manufacturing of many different products. The coating liquid is pumped to a coating die, is distributed across the width of a narrow slot in a distribution chamber and, as it exits the slot, the liquid fills the gap between the die and the moving substrate or web. Innovating and Implementing Die Coating Technology Globally There he joined the famed L.E.Scriven program in Coating Flows and earned his Ph.D. degree in 1990: his Thesis was titled “Slot Coating: Fluid Mechanics and Die Design” and was one of the first comprehensive examination of this technology’s fundamentals.

Abstract. We analyze the effects of inlet periodic pulsatile flows on the flow inside a slot-die manifold for different locations of the inlet feed port. Slot Coating - an overview | ScienceDirect Topics 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. Since the coating fluid rheology is either known or can be measured, the die can be designed to give uniform flow across the width with no adjustments. Because the viscosity is relatively low ...

Slot coating is a high precision coating method, where the film thickness is controlled by the flow rate fed to the die and the production speed. The range of desirable operating conditions for uniform coating is limited by the shape and locations of upstream and downstream menisci, which are controlled by the pressure gradient within the coating flow. The gradient can be controlled by the shape and orientation of the slot coating die, that is, die configuration. Here, the tilted die, the so ...
As described in Slot Coating: Fluid mechanics and die design, Sartor, Luigi, Ph.D. University of Minnesota, 1990, a size of the manifold portion varies depending on a distance between the manifold portion and the slit outlet (auxiliary water outlet), and a flow rate or viscosity of the auxiliary water.
