Magnetic Particles and Dye Penetrants


Liquid Penetrant Inspection (LPI) 


Penetrant testing (PT)/ Liquid Penetrant Inspection (LPI) is one of the oldest and most widely used methods for the detection of surface discontinuities in nonporous solid materials. From mid 20th century, the penetrant method has gone through a remarkable development and is now the most important method for the detection of surface defects and discontinuities.

Penetrant testing will help you find defects that are open towards the surface, like cracks and surface breaking flaws. The method is suitable for all non-porous materials such as steel, aluminium, copper, plastics, ceramics and castings.

Magnetic Particle Inspection (MPI)


Magnetic Particle Inspection (MPI) also known as Magnetic Particle Testing (MT) is a non-destructive testing method for detecting cracks, surface-breaking flaws and near-surface flaws in ferromagnetic components and structures.


Ferromagnetic materials such as iron, nickel and cobalt are strongly attracted to a magnet and can easily be magnetised. The magnetic particles gather around the defect, making it easy to locate and repair.
