Magnetic Particle Inspection Machines

Pioneers in Magnetic Particle Inspection Machines

As the oldest Indian manufacturer of Magnetic Particle Inspection (MPI) machines, Toshniwal Technologies Private Limited stands as a testament to innovation, quality, and reliability. With decades of experience, we have mastered the art of creating MPI machines that meet the highest standards of performance and efficiency.


What is an MPI Machine and How does it work?

A Magnetic Particle Inspection (MPI) machine is a powerful tool used to detect surface and subsurface defects in ferromagnetic materials. The process involves magnetizing the part and then applying ferrous particles in either a dry or wet suspension. These particles are attracted to areas of magnetic flux leakage, such as cracks or voids, creating a visible indication under UV or visible light. MPI is fast, reliable, and ideal for ensuring the integrity and safety of critical components in industries like automotive, aerospace, railways and manufacturing.

Innovative Solutions

At Toshniwal Technologies, we conceived the idea of double clamping machines, where the output of one machine is equivalent to that of two. This innovation saves space, reduces manpower, and cuts costs, offering an efficient solution for your inspection needs. Additionally, we provide extremely creative solutions to minimize heavy test job material handling, enhancing operational efficiency and safety.
