■ Precision processing equipment

High-precision Intelligent Manufacturing

Introduce medium-frequency quenching equipment and high-precision CNC lathes to realize the automation and standardization of key processes, and guarantee the fatigue resistance and coaxiality of every shaft and pipe.

CNC Precision Turning

Adopt heavy-duty double-head CNC lathes. Workpieces are clamped once and processed simultaneously at both ends, which completely eliminates axial deviations caused by traditional processes and ensures precise fitting of the hub bearing seats.

+ 21 strict quality inspection procedures

Full-process quality control

Establish a comprehensive quality inspection system covering the entire process from steel warehousing to finished product delivery. Adopt non-destructive testing and ultimate fatigue tests to guarantee absolute safety under heavy-load road conditions.

Core Testing Procedures

Non-destructive Testing and Fatigue Testing

Every batch of axles must pass ultrasonic non-destructive testing and a 1,000,000-cycle ultimate fatigue resistance stress test to eliminate all tiny cracks and internal defects and ensure load-bearing capacity under extreme road conditions.
