Stone chip tester
The Gravel Resistant Impact Tester/Stone Chip Tester is specifically designed for gravel impact testing of automotive materials and surface coatings. It meets the testing requirements of SAE, ASTM, VDA, GM, Ford, Chrysler, Mazda, JIS, Nissan, VW, and Toyota, among others.
Standards
ASTM D3170: Coating resistance to gravel impingement.
ISO 20567: Paints and varnishes – Resistance to stone chipping.
SAE J400: Automotive exterior component durability testing.
EN 14425: Aerospace material impact resistance protocols.
Product Advantages
Precision Impact Simulation: Replicates real-world gravel impact scenarios (e.g., road debris, aviation particle strikes) with adjustable speed and angle controls.
Multi-Industry Applicability: Essential for automotive body panels, aircraft skins, train coatings, and architectural finishes.
High-Speed Airflow System: Generates consistent particle velocities (20–120 m/s) for repeatable testing across samples.
Modular Design: Interchangeable nozzles and sample fixtures accommodate diverse component geometries (e.g., curved automotive panels, flat building materials).
Advanced Safety Features: Enclosed testing chamber with integrated debris shield and emergency stop function.
Data-Driven Analysis: High-resolution camera system captures pre/post-test images for quantitative damage assessment (dents, cracks, delamination).
Product Features
Airflow Control System: Digital regulation of air pressure (0.2–0.8 MPa) and particle velocity for standardized testing.
Adjustable Impact Angle: 0–90° tilt mechanism to simulate horizontal, vertical, or oblique impact angles.
Sample Fixtures: Universal clamps for securing automotive panels, aerospace composites, or building materials up to 500×500 mm.
Touchscreen Interface: Programmable test cycles, air pressure, and impact angles with real-time data logging.
Debris Recycling System: Integrated funnel and vacuum system for automated gravel collection and reuse.
Safety Interlocks: Transparent enclosure with light curtains to halt operation during access attempts.
