Automatic Scratch Test machine

The Automatic Scratch Test Machine is a precision testing instrument designed to evaluate the adhesion strength and bonding performance of coatings with a thickness of ≥1 μm through controlled scratch loading. By applying well-defined mechanical loads and monitoring coating failure behavior, the system enables objective assessment of coating durability, interfacial strength, and scratch resistance. The fully motorized platform and automated data acquisition make the system suitable for both laboratory research and industrial quality control applications.
