Magnetic Particle Inspection

Yantai Haige Machine Tools Co., Ltd. Was built in 1999, which specializes in producing steel finishing equipment, such as magnetic particle inspection, Series JY Bar Straightening Machine, Abrasive Belt Ginder, Drawing Machine, Shot Blasting Machine, Centerless Grinding Machine, CNC skiving and Roller Burnishing Machine and Auxiliary Machine etc. We also engage in continuous hard chrome plating equipment and heat treatment equipment.


Magnetic particle inspection utilizes the interaction of the leakage magnetic field at the defect of the work-piece with the magnetic particle. It utilizes the difference in magnetic permeability and steel permeability between surface and near-surface defects (such as cracks, slag inclusions, and grain lines) of steel products. The magnetic field at the discontinuity of the material will be distorted, and part of the magnetic flux leakage will generate a leakage magnetic field at the surface of the work-piece, thereby attracting magnetic powder to form a magnetic powder accumulation defect—magnetic marks. Under appropriate lighting conditions, the position and shape of defects will be revealed. The observation and interpretation of the accumulation of these magnetic particles enabled magnetic particle inspection. By using our equipment, it can be guaranteed that the product quality, using security, lower cost.
