Gravel Resistant Impact Tester/Stone chip tester

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.
