Slot die coating enables even distribution of a pre-metered coating to be applied to a web. They can be used for coating aqueous, solvent or hot melt coatings.

High-precision slot die coating equipment Slot-die coating is a coating technique in which a solution is delivered onto a substrate via a narrow slot positioned close to the surface. The slot-die has a high aspect ratio outlet controlling the final delivery of the coating liquid onto the substrate. This results in the continuous production of a wide layer of coated material on the substrate, with adjustable width depending on the dimensions of the slot-die outlet. By closely controlling the rate of solution deposition and the relative speed of the substrate, slot-die coating affords thin material coatings with easily controllable thicknesses in the range of 10 nanometers to hundreds of micrometers after evaporation of the precursor solvent.

The equipment is transported to the coating area through the unwinding mechanism. The battery slurry is stably transported to the coating slot die head
