Air knife coating is a manufacturing process that uses compressed air to blow a thin and uniform layer of liquid or powder material onto a surface. It is often used in industrial settings to coat materials such as paper, plastics, and metals, and is valued for its precision, efficiency, and consistency. Air knife coating involves passing the material to be coated over a series of air knives that apply a controlled flow of air to distribute the coating material evenly across the surface. The process can be adjusted to accommodate different coating materials, substrate materials, and production requirements.
