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.

High precision slit coating equipment DT-700-2300
The coating system mainly comprises a feeding unit and a coating unit. The coating unit is composed of precision-machined upper and lower molds and thin gaskets installed between the upper and lower molds. The feeding unit is composed of a storage and conveying injection pump and a filtering device. The system consists of precise movement of the coating die relative to the substrate, by controlling the rate, precise metering and pumping of the process fluid, liquid chemical material is extruded and coated on the moving substrate (glass, stainless steel and plastic) from the gap between the upper and lower dies to form a thin film. The thickness of the coating film can be calculated directly from the liquid flow rate and the moving speed of the substrate. The advantage is that the film uniformity is high, the applicable coating viscosity range is wide, the coating speed is fast, and a large area of the film can be produced.
