Doctor Blade Laboratory Coating Machine

The laboratory coating machine with a doctor blade evenly spreads the coating into a wet film of specified thickness by driving the blade to move at a constant speed over the substrate surface via a motor. It is used to simulate the industrial coating process, test the leveling, hiding power, and other properties of coatings, and is suitable for laboratory preparation and quality control of inks and paper.
Selection
When selecting, consider the compatibility of the substrate width with the machine specifications, ensure the scraper accuracy meets the coating thickness requirements, and note that the motor type affects speed stability. Additional features such as heating plates or vacuum adsorption should be configured based on experimental needs, and the operation interface should be simple and clear.
