Leather Seam Fatigue Tester

Produced by: Qinsun Instruments Co., LTD

All supplier products

Standards

ISO 5402: Leather physical testing – Flex tester method for adhesion and strength analysis.
SATRA TM55: Seam fatigue testing for footwear, ensuring stitching integrity under cyclic stress.
ASTM D6193: Loop strength testing for leather goods, critical for accessories like belts and bags.
GB/T 3903.32: Chinese national standard for footwear seam fatigue resistance.
EN 13520: Flexometer testing for coated fabrics, validating bonding durability in automotive interiors.

Product Advantages

Multi-Station Efficiency: Simultaneously test up to 4 samples, accelerating QC workflows and reducing testing time.
Precision Flex Simulation: Adjustable stroke frequency (100–300 cycles/min) and bending angles (0–90°) replicate real-world wear patterns.
Versatile Applications: Ideal for footwear, automotive upholstery, fashion accessories, and industrial textiles.
User-Centric Design: PLC-based touchscreen control with programmable cycles, angles, and loads for automated testing.
Data-Driven Insights: Built-in cycle counter and failure detection for objective pass/fail criteria (e.g., stitch breakage thresholds).
Compact Durability: Robust construction with a 120W motor and 50N load capacity for heavy-duty use in industrial labs.

Product Features

Quad-Testing Stations: Independent clamping mechanisms for parallel evaluation of seams, loops, or bonded joints.
Customizable Testing Modes:
- Seam Fatigue: SATRA/ISO-compliant bending cycles (e.g., 50,000 cycles for footwear uppers).
- Loop Strength: ASTM-standard tension tests for leather accessories.
- Adhesion Integrity: EN 13520-compliant coating delamination analysis.
Advanced Control System:
- 7-inch touchscreen with preset protocols for footwear, automotive, and fashion industries.
- Adjustable load cell (0–50N) for tension/compression testing.
Fail-Safe Mechanisms: Auto-stop function upon seam failure or cycle completion, with real-time data logging.
Ergonomic Design: Quick-release clamps for rapid sample mounting and tool-free angle adjustments.
