Product Overview

Core Product Competitive Advantages

1. Integrated built‑in pneumatic power assembly
   Self‑contained air compressor removes requirement for external air source. Automatic constant‑pressure control maintains stable driving force, ensuring consistent high‑speed pulling output across repeated test cycles.
2. High‑speed sudden‑pull impact performance
   Achieves breaking velocity ≥2 m/s, fully meeting standard‑mandated impact‑pull‑test conditions. Sample clamping mechanism prevents specimen slippage during rapid tensile fracture, avoiding distorted test observations.
3. Rigid compact benchtop cabinet construction
   Heavy‑duty metal frame guarantees structural stability under pneumatic impact loads. Optimised footprint occupies limited lab‑bench area for daily QC‑testing workflows.
4. Simple manual‑operation workflow
   Straight‑forward specimen clamping and one‑trigger test start. Operators visually examine paint‑film condition after wire fracture, no complicated programming required for routine batch‑tests.
5. Low‑power stable operation
   Low power consumption below 100 W. Suitable for long‑duration continuous‑running in factory quality‑control stations.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation
   Position unit on solid level workbench. Connect mains‑power‑supply. Complete equipment warm‑up for internal pneumatic system. Prepare enameled‑wire test‑specimens cut to standard test‑length.
2. Specimen Clamping
   Secure both ends of enameled‑wire sample firmly inside upper and lower fixture jaws. Double‑check clamping tightness to eliminate wire‑slippage risk during high‑speed pulling.
3. Trigger Sudden‑Break Test
   Activate test‑trigger. Pneumatic drive pulls the wire sample at speed ≥2 m/s until conductor fractures. Keep cabinet closed during impact‑pull procedure for operator safety.
4. Post‑Fracture Specimen Evaluation
   Open fixture, retrieve broken‑wire sample. Carefully inspect enamel paint‑film around fracture point for cracking, peeling or delamination. Record paint‑film adhesion performance for quality‑report filing.
5. Post‑Test Tidying
   Clear wire fragments from fixture zone. Power‑off instrument after finishing batch‑testing. Periodically inspect clamping‑jaw wear condition and pneumatic‑system pressure stability.
