Leather flexural tester

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.
