Product Overview
MPI Machines (Magnetic Particle Inspection Machines)
MAYURESH ENGINEERS designs and manufactures a comprehensive range of MPI Machines for detecting surface and near-surface cracks in ferromagnetic materials like steel, iron, and nickel alloys. These machines work by magnetizing the component and applying magnetic particles that gather around any discontinuity, forming a visible indication of cracks or defects.
What is MPI Machine/Crack Detector Equipment?
Magnetic Particle Inspection (MPI) Machine, also known as a Crack Detector Machine, is a vital part of Non-Destructive Testing (NDT) technology used for detecting surface and near-surface defects in ferromagnetic materials such as iron, steel, and nickel alloys.
These machines help ensure that critical industrial components — like shafts, gears, crankshafts, axles, and weld joints — are free from cracks, seams, laps, or other discontinuities that may cause failure during operation. MPI Machines are widely used in automotive, aerospace, railways, heavy engineering, foundries, and fabrication industries for quality control and safety assurance.
How Does an MPI Machine Work?
The working principle of Magnetic Particle Inspection (MPI) Machine is based on the magnetization of the test specimen and the observation of magnetic flux leakage. When a ferromagnetic component is magnetized, the magnetic field flows uniformly through it. If there is any crack or discontinuity, the field leaks out at that point.
When magnetic particles — either dry powder or wet suspension — are applied to the surface, they are attracted to the leakage area, forming a visible indication of the defect. The operator can then observe these indications under white light or UV (black) light, depending on the type of magnetic particles used.
This process helps detect:
- Surface cracks
- Subsurface flaws (near surface)
- Laps, seams, and inclusions
- Fatigue cracks and weld defects
All of this is achieved without damaging or altering the part being tested, making MPI one of the most efficient and economical NDT methods available.
Types of MPI Machines (Crack Detectors)
Depending on the inspection requirement and work environment, different types of Magnetic Particle Inspection Equipment are available:
- Bench Type MPI Machines: These are robust, stationary machines ideal for high-volume production testing. They are equipped with head and tail stocks, current control units, and particle application systems. Perfect for testing medium to small-sized components such as shafts, bolts, and rings.
- Portable MPI Units: Designed for on-site inspection, portable MPI machines are lightweight and easy to operate. They are ideal for large or immovable structures such as pipelines, welded joints, pressure vessels, and heavy castings.
- Wet Horizontal MPI Machines: These machines use wet suspension magnetic particles for higher sensitivity and better coverage, suitable for detailed laboratory and precision testing.
- Customized MPI Systems: Advanced systems can be customized based on component geometry, magnetizing current, and testing standards. Automated or semi-automatic crack detection machines improve productivity and consistency
