A vertical MPI (Magnetic Particle Inspection) Testing Machine is used to detect cracks that are on the surface or subsurface of metal components. Magnetism is the principle by which the machine is operated. When the metal component carries a magnetic field, it leaves behind a leakage field when a crack or other defect is present. Iron particles, in the form of a dry powder or wet solution, aggregate at these places and make the defect visible.
The machine is termed "vertical" because the component is placed in an upright position during testing. This machine is suitable for testing round and heavy components, like shafts, axles, and rods. Vertical MPI machines are mostly found in automotive, aerospace, railways, and foundry industries.
They provide accurate and fast testing, which reduces time and enhances safety. Some of these machines are even semi-automatic, while others are fully automatic, depending on the model. One of the most important aspects of the vertical mpi testing machine is that it aids in perfect quality assurance processes for defect-free metal components.
