Preventing Major Quality Issues with “Eddy Current Testing”

Imagine this scenario:
One day, you suddenly discover that a specific production lot contains different materials, abnormal heat treatment, or even skipped processes. Such issues could easily escalate into a serious quality problem.

The big question then becomes:
“How can we reliably prevent defective parts (NG) from escaping downstream?”
But here’s the reality…
・Visual inspection cannot reveal the problem.
・Measuring dimensions or weight shows no difference.
・Performing destructive testing on every single part is impossible—it would take enormous time and cost.

This is where the FTS-eddy1 Eddy Current Tester comes in.

Using a comparative method with a master coil and test coil, it can detect:

①Large cracks or defects　 ②Material and shape differences　③Abnormal hardness

What makes it different:
・Conventional hardness testing relies on destructive sampling.
・With FTS-eddy1, you can perform non-destructive testing.
・And achieve 100% inspection, whether it’s 10,000 or 100,000 parts.

In mass production, hardness abnormalities or material mismatches are issues that should never occur. But if they do, this technology serves as your ultimate safeguard for full-lot quality assurance.

Combination of Camera and Eddy sorting

By integrating EDDY into a NANO standard machine, material mix-up and hardness issues can be inspected in the same cycle time as conventional image inspection (dimensions, deformation, wrong parts).
