Gravel Resistant Impact Tester
Application
1. Automotive Industry
Vehicle Body Coating Testing: Testing the chip resistance of coatings on car chassis, doors, bumpers, etc., to ensure long-term appearance and corrosion protection during driving.
Windshield and Headlight Protection: Verifying the impact resistance of glass and plastic components to meet safety standards.
New Energy Vehicles: Increased demand for impact testing of battery pack casings and charging pile surface coatings.
Strict industry standards (such as ISO 20567-1. SAE J400) drive testing requirements.
2. Aerospace
Aircraft Engine Components: Testing the ability of blades, air intakes, and other parts to withstand sand and stone impact in high-speed airflow.
Aircraft Fuselage Coatings: Evaluating the durability of aircraft surface coatings in extreme climates (such as deserts and high altitudes).
3. New Energy and Wind Power
Wind Turbine Blades: Testing the impact resistance of blade coatings against wind, sand, and rain erosion to extend service life.
Solar Panels: Verifying the resistance of photovoltaic panel surfaces to hail and dust.
4. Rail Transit
High-speed/Subway Train Bodies: Testing the performance of train body coatings and glass in resisting track debris impact during high-speed operation.
Rail Transit Equipment: Testing of protective layers for signal equipment and overhead line components.
5. Building Materials and Construction Industry
Building Glass Curtain Walls: Simulating wind, sand, and hail impact to test their shatter resistance.
Exterior Wall Coatings and Metal Panels: Evaluating the durability of coatings in outdoor environments.
6. Consumer Electronics and Home Appliances
Mobile Phone/Camera Lenses: Testing the scratch resistance of screen or lens coatings against sand and grit.
Outdoor Electrical Equipment: Verification of weather resistance for devices such as surveillance cameras and drone casings.
