【Product Overview】

JunYan Brand Automatic U-Bend Fatigue Tester is engineered for rigorous flex life testing of wires, cables, and connectors. Compliant with IEC 60335, UL 2556, and ISO 6722 standards, it simulates 180° U-shaped bending cycles up to 100,000 times, ensuring 40% lower cable failure rates for clients like Tesla and Huawei. Ideal for automotive harnesses, EV charging cables, and consumer electronics durability validation.

【Core Advantages】

✅ Submicron Precision Control
Servo-driven system + 0.01N force resolution ensures ±0.1° bending angle accuracy and ±0.05mm displacement control. Detects micro-cracks and conductor fractures with <0.5% data deviation.

✅ Smart Automated Testing
7" industrial HMI preloads 30+ programs (fixed-angle bending, cyclic fatigue, auto-stop on fracture). Real-time force-displacement curve display, PDF/Excel report generation, and MES integration streamline QA workflows.

✅ Industrial-Grade Durability
Tungsten steel grips + high-carbon steel frame withstand 500,000+ cycles at 10-60 cycles/min. Energy consumption reduced by 50%, maintenance costs cut by 60%.

✅ Multi-Scenario Adaptability
Modular fixtures support round/flat/shielded wires (φ0.5mm-20mm). Optional environmental chamber (-40℃~+85℃) and multi-station testing for robotics/medical cable certifications.
