Automotive wire cyclic bending testing machine

Standard 
This testing machine aligns with global automotive industry standards for wire harness reliability, including ISO 6722 (Road vehicles – Cables for conductor sets) and SAE J1128 (Low-voltage battery cable specifications). By simulating repetitive bending stresses, it evaluates wire fatigue resistance under dynamic conditions, ensuring compliance with OEM specifications for in-vehicle wiring durability.

Product Advantages

1. Versatile Angle Adjustment: Swings up to 180° bi-directionally or any user-defined angle, accommodating sharp-bend (e.g., R3.75) and gradual-curve testing scenarios.
2. Triple-Station Efficiency: Three independent test channels enable parallel testing of different wire specifications, tripling throughput compared to single-station machines.
3. Precision Fatigue Analysis: ±1 cycle/min speed control and 6-digit counter ensure accurate life-cycle prediction, critical for validating warranty periods.
4. Adaptive Fixture System: Interchangeable R-angle fixtures (R3.75, R7.2, R9.6, etc.) cater to wires from thin gauge (0.5mm²) to heavy-duty cables, eliminating costly retooling.
5. Safety & Data Integrity: Automatic stop-on-break function prevents post-failure damage, while memory retention resumes testing after power interruptions.

Product Features

• Dynamic Swing Mechanism: 180° rotation with adjustable angles (1° increments) via digital control panel.
