Product Overview

Core Product Competitive Advantages

1. Standard‑compliant 90‑degree reciprocating‑bending mechanical system
   Equipped with Φ30 mm bending mandrel. Strictly reproduces 90° flexing angle as‑per international footwear‑test‑norms. Stable drive‑mechanism maintains 125 cycles‑per‑minute operating speed to simulate repeated foot‑bending stress in real‑wear scenarios.
2. Three‑station simultaneous‑test fixture assembly
   Three independent clamping positions allow three sole‑specimens to run fatigue‑testing in parallel. Wide‑opening 155 mm‑width clamps fit most common‑size shoe‑outsoles. Jigs are easy to release and lock for rapid sample swap‑over.
3. High‑capacity digital cycle‑counting module
   Large‑range LCD counter covers 0‑999 999 cycles. Users pre‑set target bending‑cycles; machine automatically stops once reaching assigned value. It removes manual‑timing errors for batch‑QC workflows.
4. Transparent protective safety‑housing
   Full‑cover clear safety‑shield isolates moving flex‑linkage components, preventing operator‑contact injury during machine‑operation. Operators can still observe specimen‑bending status through the transparent cover.
5. Robust integrated cabinet & simple panel operation
   Heavy‑duty welded main‑frame minimises vibration during long‑hour continuous cyclic‑testing. Front‑panel keypad‑and‑display layout provides straightforward parameter setup, requiring minimal operator‑training.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation

   Position tester on solid horizontal lab‑floor or heavy‑duty work‑bench. Check linkage‑mechanism and clamp‑jig condition. Punch standard incision holes at designated maximum‑bending‑stress location on sole specimens as‑per‑standard requirements. Power‑on unit and run short idle cycle to verify smooth mechanical‑motion.
2. Specimen Mounting
   Open protective transparent cover. Secure each prepared sole‑specimen firmly onto respective clamping station. Confirm incision position aligns right above the bending mandrel. Tighten fixture locks and close safety‑housing cover. Configure target bending‑cycle value via front‑panel keypad.
3. Launch Bending‑Fatigue Test
   Press run‑button. Machine executes continuous 90‑degree reciprocating flexing for all three stations simultaneously. Counter accumulates completed cycles in real‑time. Equipment will auto‑halt upon reaching preset cycle‑threshold.
4. Post‑Test Observation & Result Recording
   Open safety‑cover after machine fully stops. Take‑off tested sole‑samples. Inspect incision‑extension, crack generation and tear‑propagation under magnifying‑tool. Document crack‑length data for pass‑fail judgement. Multiple‑batch replicate‑tests are suggested for statistically‑valid evaluation conclusion.
5. Post‑Test Tidying
   Remove finished specimens. Clear rubber / polymer debris inside test‑chamber. Reset counter parameters for next‑group testing. Periodically inspect fasteners, linkage‑pivots and clamp‑jig wear‑condition.
