Precision Optical Film Coating Machine

The precision optical film Coater controls the coating flow through a metering pump, evenly applies the coating onto the substrate surface using a blade or micro-gravure roller, and cures it in an oven to form an optical film. It is used to manufacture optical components such as brightness enhancement films and anti-glare films, and is applied in the fields of display screens and photovoltaic backplanes.
Selection
When selecting, consider the substrate width matching the coating width, the coating thickness corresponding to precision requirements, the drying method suiting the solvent type, the operating speed meeting production capacity demands, and the equipment material's corrosion resistance aligning with the coating characteristics.
