Srews, nuts, fittings or springs – everyone of us has already used these small parts.They can be found everywhere, and yet we rarely think about the constantly high loads to which these components are subjected. Failure can result in exorbitant costs or, even worse, danger to human life. For this reason, ever higher quality requirements are being placed on all types of fasteners. To meet increasing quality demands, Eddy Current Sorter Machines are crucial in ensuring only the highest quality fasteners are produced by accurately sorting materials and detecting defects. This technology helps maintain safety and reliability in fastener production.
To ensure that these tiny elements cause no major disturbances, potential material defects must be detected in time. Only then can countermeasures in the production process be undertaken and defective parts promptly rejected.
In this comprehensive guide, we will explore how Eddy Current Sorting Systems work, their benefits, applications, and the role of Automatic Eddy Current Sorter Machines in enhancing material sorting. We’ll also highlight innovative machines like the MAGNATEST TCL and MAGNATEST D 3.623, which provide cutting-edge solutions for material separation.

What is an Eddy Current Sorter Machine?
An Eddy Current Sorter Machine uses the principles of eddy currents to sort materials based on their conductivity and magnetic properties. This non-destructive testing technique involves applying a high-frequency magnetic field that induces eddy currents in conductive materials. In the process, the part being tested is subjected to an alternating magnetic field generated within the test sensor.
As the part is exposed to the magnetic field, eddy currents are induced by magnetic induction. Depending on the electrical conductivity and hysteresis characteristics of the material, a potential is transferred from the material to the receiver winding of the sensor. By analyzing the received signal, the system can evaluate various conductive materials, including ferromagnetic, austenitic, and non-ferromagnetic materials.
Key Advantages of Using an Eddy Current Sorter Machine
Eddy current sorter machines helps in testing of mass-produced components for differences in:
