Magnetic Particle Testing Machine MPI Equipment for Ring-Shaped Parts

Customized MPI machine for ring components and short shafts, offering wet fluorescent inspection, flexible magnetization, and industrial B2B manufacturing performance.

  • Suitable for Ring Components and Short Shaft Inspection
    The machine is designed not only for bearing rings, forged rings, and gear rings, but also for short shafts and sleeve-type components, providing versatile inspection capability within a single system.

  • Multiple Magnetization Methods for Full Defect Coverage
    Supports circumferential and longitudinal magnetization with optional AC, DC, or combined modes, ensuring effective detection of surface and near-surface defects on both ring-shaped parts and short shafts.

  • Wet Fluorescent MPI with High Sensitivity
    Utilizes wet fluorescent magnetic particle inspection in combination with high-intensity UV illumination, delivering clear and reliable indication of fine cracks, laps, and inclusions.

  • Customized Design for Various Workpiece Sizes
    The system can be customized according to workpiece diameter, length, weight, and production rate. Dedicated fixtures and magnetization configurations enable quick changeover between ring components and short shafts.

  • Stable Structure and User-Friendly Operation
    Built with industrial-grade mechanical and electrical components, the machine offers stable performance, intuitive operation, and low maintenance cost, making it suitable for continuous industrial use.

The ring components magnetic particle inspection machine is designed for reliable detection of surface and near-surface defects on ring-shaped parts and short shafts. It is widely used for bearing rings, forged rings, gear rings, sleeves, and short shaft components in industrial production environments.

This magnetic particle inspection machine supports circumferential and longitudinal magnetization, with optional AC, DC, or combined magnetization modes. By optimizing the magnetic field distribution, the system ensures complete inspection coverage of critical areas where cracks, laps, and inclusions are most likely to occur.

Equipped with wet fluorescent magnetic particle inspection technology, the machine delivers high inspection sensitivity and clear defect indication. When combined with a high-intensity UV lamp, even fine cracks can be detected reliably, improving inspection accuracy and reducing the risk of defective parts entering subsequent processes.

To meet different production requirements, the customized MPI machine for ring components and short shafts can be tailored according to workpiece diameter, length, weight, and inspection cycle time. Dedicated fixtures and adjustable magnetization parameters allow quick changeover between different ring sizes and short shaft configurations, enhancing production flexibility.

From a customer value perspective, this industrial magnetic particle inspection equipment helps manufacturers improve product quality, reduce rework and scrap rates, and ensure compliance with internal quality standards and international inspection requirements. Its stable structure, user-friendly operation, and low maintenance design make it a cost-effective solution for long-term B2B manufacturing applications.
