Vacuum Coating Test Machine

The vacuum coating tester operates by creating a vacuum within a sealed chamber and uniformly applying coating materials onto a substrate surface using a blade or roller. It is used to simulate industrial coating processes, testing the adhesion, thickness, and uniformity of coatings on various substrates. This equipment is suitable for laboratory research and quality control of materials such as paper and films.
Selection
Consider the coating speed range, vacuum control accuracy, applicable substrate dimensions, and material compatibility when selecting. Match coating methods such as blade or micro-gravure, and pay attention to temperature control systems and coating thickness adjustment functions. Choose the appropriate model based on the viscosity of commonly used coatings, ensuring the equipment is easy to clean and maintain.
