Magnetic Particle Testing Equipment

Magnetic Particle Testing (MPT) is a powerful inspection method used to detect surface and subsurface discontinuities in ferromagnetic materials. As an essential service under Third-Party Inspection, MPT plays a crucial role in assuring the quality, safety, and longevity of various products and components.

The Need for Magnetic Particle Testing

In today’s competitive marketplace, the integrity and reliability of products have become paramount. Magnetic Particle Testing, when conducted by an impartial third party, serves as a trusted means to:


  • Identify Potential Weaknesses: Detect cracks, seams, and other imperfections that might affect performance.
  • Assure Compliance: Ensure that products meet regulatory requirements and industry standards.
  • Build Confidence: Enhance customer trust by demonstrating a commitment to quality.
  • Reduce Risks: Minimize the likelihood of future failures, reducing both downtime and liability.


  • Improved Product Quality: Early detection of flaws leads to better products.
  • Increased Operational Efficiency: Reduced downtime and maintenance costs.
  • Enhanced Reputation: Recognition for adherence to quality, environmental, and safety standards.
  • Risk Mitigation: By uncovering hidden defects, potential hazards can be averted.

Process of Conducting Magnetic Particle Testing

Our step-by-step process ensures the highest level of accuracy and reliability:

  1. Preparation of the Test Surface: Cleaning the surface to remove dirt, paint, or coatings.
  2. Application of Magnetic Field: Creating a magnetic field within the material using a suitable magnetizing technique.
  3. Particle Application: Applying magnetic particles that are attracted to areas with magnetic flux leakage.
  4. Examination: Carefully inspecting the test surface under proper lighting to detect indications.
  5. Interpretation and Evaluation: Analyzing indications to determine if they are relevant to quality and safety.
  6. Demagnetization: Removing the residual magnetic field.
  7. Documentation: A comprehensive report with findings, recommendations, and compliance status.

Magnetic Particle Testing under Third-Party Inspection is not just a routine procedure; it’s a strategic approach to quality control and risk management. By leveraging our expert services, organizations can make informed decisions, foster continuous improvement, and sustain a competitive edge.

    Multi-directional MPI Bench

    This machine produces multi-directional magnetization to detect defects in all orientations in a single shot. This is different from the combined magnetization shot used in conventional machines, which is not as per ASTM standards.

    PLC Controlled MPI Machine

    Our PLC-based MPI test bench units go a step ahead of conventional machines for MPI inspection. They are used across a wide range of industries, such as aerospace, marine automotive, oilfield equipment & railways.

    Standard MPI Machine

    Our standard MPI test bench units set the standard for MPI inspection. They are used across a wide range of industries, such as automotive, fasteners, hand tools, oil field equipment, railways, and education & training for the detection of surface & subsurface defects. These benches are two vector machines.

    MPI Machine for aerospace parts

    These machines are suitable for the detection of surface & subsurface defects in aerospace parts. These machines comply with ASTM E1444 & E709.

    Magnetic Crack Detector

    This machine is a wet horizontal bench-type unidirectional machine that generates circular magnetization meant for checking both bright & black rolled steel round bars. 

    Mobile Current Generators

    Our mobile current generators are suited for testing large and very heavy parts using the magnetic particle inspection method. Suitable for parts that can’t be loaded on a stationery-type machine. These units feature AC and Half Wave DC output.


    Demagnetizers play a crucial role in various industries by effectively removing residual magnetism, thus ensuring the quality and functionality of the final products.

    UV LED Lights

    LED Based UV Lights are lightweight, consume less power, are switched on instantaneously and don’t use harmful mercury. Used for fluorescent inspection.

    Residual Field Indicators

    Residual field indicators measure the magnetic field left in the part after magnetization & demagnetization. Proper demagnetization is a necessary part of MPI standards.
