How Does ECT, EOT, and EVT Testing Ensure Zero-Defect Steel Balls?

At Tolia, we don't just manufacture - we guarantee quality through 100% inspection using three advanced non-destructive testing methods:

ECT (Eddy Current Testing):

Detects subsurface cracks, inclusions, and material inconsistencies using electromagnetic fields.

EOT (Electro-Optical Testing):

Uses laser technology to identify surface defects like scratches, stains, or poor polish.

Checks for shape irregularities (ovality) and missing material by analysing vibration patterns.

Unlike random sampling used by many manufacturers, every single Tolia steel ball passes through all three tests. This ensures zero defects, perfect sphericity, and consistent performance - giving our customers complete peace of mind.

We are one of the few manufacturers in India offering 100% ECT + EOT + EVT on every ball.
