Kerone specializes in innovative thermal processing solutions. With expertise in industrial applications, we also offer slot die coating, providing comprehensive solutions for precise and uniform coating applications. Slot die coating is a precision deposition technique used to apply thin and uniform layers of liquid onto substrates. This solution produces a firm solid layer in this process when it enters a small opening and comes into touch with the material. It is commonly used for applications requiring precise coating thickness and uniformity in a variety of sectors, including electronics, optics, and pharmaceuticals. Because slot die coating can control flow rates and provide an equal coating length, it has an advantage over other techniques. For the production of goods like flexible electrical equipment, solar cells, and medicinal devices where precise deposit is important for both the functionality and the quality of the final product it is important.

Slot die coating is a pre-metered coating technology that simplifies the computation of wet-film thickness by determining the ultimate thickness only based on solution ...
... flow rates. It provides a wider processing window than traditional roll-to-roll techniques, which is highly beneficial for researchers looking to scale up thin film manufacturing. The application of slot die coating is becoming more and more common in industries including photonic structures, quantum dots, perovskite and polymer solar power, and natural light-emitting diodes. Even though it is more involved than other deposition methods, careful design considerations such as material characteristics and slot geometry can significantly increase coating consistency. This lessens the impact of processing variables on the quality of the deposition and offers the fine control needed for sophisticated applications.
