Coil Coating Tester

The coil coating tester uses a motor to drive the substrate at a constant speed through the coating head, with a blade or roller controlling the coating thickness to form a uniform coating on the substrate surface. It is used to simulate the coating process in production lines, test parameters such as coating adhesion and thickness uniformity, and is suitable for laboratory coating process development of materials such as paper, films, and metal foils.
Selection
When selecting, consider the substrate width and thickness range, ensure the coating speed matches production requirements, and choose the coating method (blade or micro-gravure) based on the characteristics of the coating material. The temperature control system must adapt to the drying conditions of the coating, and the material contact parts need to be corrosion-resistant. The equipment's precision should meet the requirements for coating thickness control, and the operation interface should be simple and easy to maintain.
