Quality · Equipment
Comprehensive lab infrastructure, end-to-end standardization
Four laboratories plus a non-destructive testing center cover product testing from alloy chemistry to finished-part durability — proprietary instrumentation across the chain lets Hetian build customized solutions to manufacturing challenges with professional efficiency.

Lab V · Durability
Fatigue & Durability Lab V
Multi-station fatigue benches for ball joints, bushings and control-arm assemblies — swing-angle endurance, torque retention and load-cycle life at temperature extremes.
NDT Center
Non-Destructive Testing Center
- X-ray defect detector
- Automated fluorescent penetrant inspection line
Three automatic fluorescent penetrant lines across a dedicated inspection area, plus X-ray bays for internal porosity in cast arms — internal defects found before the parts ship, not after.

On the Line
Inspection isn’t a lab-only job
8,800 m² · 1M pcs/yr
X-ray detection
Dedicated X-ray bays screen die-cast control arms for internal porosity — every critical casting, not a sample.
2,000 m² · 3 lines
Fluorescent penetrant inspection
Three automatic FPI lines reveal surface cracks that the eye misses — on forged arms, before machining hides them.
Assembly · EOL
End-of-line checks
Air-tightness testing, torque and swing-angle measurement and QR-code laser marking close the loop — every unit traceable, every unit checked.
