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.
