DuPont Impact Tester is a professional testing instrument used to evaluate the damage resistance of materials (such as coatings, films, metal plates, etc.) under impact loads. It tests its crack resistance, adhesion, and impact resistance by simulating the free fall of heavy objects hitting the material surface. Place the test piece with the coating surface facing up under the machine’s bumping head, and check the damage and deformation after being hit by the heavy hammer at a certain height. It is widely used in quality control and R&D in coatings, plastics, metals, and other industries.
