Standards

  • EN ISO 20344:6.6: Safety footwear leather flexing resistance.
  • I.U.P.10+20/I.U.P.20: International Union of Leather Technologists protocols for crease crack analysis.
  • UNI 4818: Italian standard for leather flex endurance.
  • DIN 53.351: German industrial standard for material bending fatigue.
  • UNE/I.U.P.20: Spanish national standard for protective footwear upper testing.

Product Advantages

  • Multi-Station Efficiency: 12-station configuration enables parallel testing of leather samples, reducing batch evaluation time by up to 75%.
  • Automated Operation: Pre-programmed cycle counter with auto-stop function eliminates continuous monitoring, enhancing lab productivity.
  • Temperature Control: Optional low-temperature variants (-20°C to ambient) simulate extreme climatic conditions for protective footwear testing.
  • Ergonomic Design: Bench-mounted unit with tool-free sample clamping and intuitive control panel for rapid setup.
  • Global Compliance: Meets critical standards for automotive interiors, safety footwear, and luxury leather goods.
  • Surface Finish Analysis: Detects micro-cracks and coating delamination in creased areas, critical for assessing wear in dress shoes and bags.

Product Features

  • Flexing Mechanism: Rotary bending arm applies 180° reciprocal motion to leather samples at 100 ±5 cycles/min.
  • Sample Mounting: 12 independent clamps with adjustable tension screws accommodate leather strips (70×45 mm) and finished footwear uppers.
  • Digital Control System:
    • Programmable cycles (1–999,999) with pause/resume functionality.
    • Real-time cycle counter and failure alerts (e.g., stitch breakage, coating cracks).
  • Temperature Regulation:
    • Ambient to -20°C operation (low-temp models) with digital thermostat.
    • Insulated chamber minimizes condensation during cold testing.
  • Safety Features: Emergency stop button, over-cycle protection, and non-slip bench mount.
