An MPI testing machine is mainly used to check metal parts before they are used in real work. Many times small defects are there, but they are not visible by eyes. That is where this machine helps. From a normal person’s thinking, the main job of this machine is to make sure the metal part is safe and strong.
The working is not very complicated. First the metal part is magnetized, then magnetic powder or liquid is applied on it. If there is any demage, the particles slowly collect there and make the defect visible. The good thing is, the part does not get damaged during testing.
These machines are commonly used in factories, workshops, automotive units, railways and casting industries. People trust MPI testing because it is fast and reliable. In simple words, an MPI testing machine helps avoid future problems, saves cost, and gives confidence that the product quality is proper before use.
