The Wheelset Magnetic Particle Inspection (MPI) Machine is a specialized non-destructive testing system designed for the detection of surface and slightly subsurface defects on railway wheelsets, including axles, wheel rims, and treads. Equipped with high-sensitivity fluorescent magnetic particle testing, the system ensures accurate and reliable flaw detection critical for railway safety and maintenance.

This equipment provides 360-degree circumferential magnetization with both AC and DC magnetizing options, meeting the inspection needs of various defect orientations. It adopts PLC control with a human-machine interface (HMI), enabling intuitive operation, data recording, and real-time monitoring of test parameters.

Engineered for heavy-duty applications, the machine features a robust frame structure, long-life magnetizing coils, and automated spraying and demagnetization systems to reduce manual intervention and inspection time.

✅ By using the Wheelset MPI system, customers benefit from:

Enhanced inspection efficiency and reduced labor cost
Compliance with railway NDT standards
Increased reliability of wheelsets in service
Seamless integration into existing inspection lines
