Quality Commitment

Quality Is Our Powertrain DNA

We engineer "Zero Defect" into every component through IATF 16949-certified systems:

Prevention Over Correction

AI-powered real-time SPC halts production at 0.1mm dimensional drift
Raw material defect rate < 50PPM (vs. 500PPM industry avg.)

Traceability As Standard

Laser-etched UID enables 5-second root cause tracing (material batch → operator log)

Every Employee A Guardian

Quality KPIs weigh 40% in performance reviews 2.6 improvement ideas/employee/year implemented
