Real results from real customers, published only with their agreement, and every performance figure backed by the measurement data behind it.
Published case studies
Automating Crack Detection in Ceramic Roof Tiles
Replacing manual tap-testing on a roof-tile line with an automated impulse-excitation check that reliably separates sound tiles from cracked ones.
→ AerospaceCatching a Hidden Flaw in Aerospace Brake Discs
An impulse-excitation screen flagged one structurally compromised brake disc that had passed conventional inspection — caught by how it damped, not just how it rang.
→ Safety-Critical ManufacturingTuning an Inline Pass/Fail Station to the Customer's Own Parts
A GrindoSonic engineer went on-site to adapt an inline GO/NOGO station to a transport supplier's specific parts — objective production QC in under three seconds, dialled in to their geometry.
→ Medical DevicesVerifying Medical Assemblies by Their Resonant Fingerprint
A correctly built assembly rings at a characteristic frequency; a missing internal part changes the tune. IET turns that into an automatic, non-destructive build-verification check.
→What a case study here always is
Measured, not claimed
Every number comes from an actual IET measurement on the customer’s material, no estimates, no marketing math.
Published with permission
A case appears only after the customer signs off on what we show, including any images and figures.
Specific and reproducible
Material, property measured, and result, described precisely enough to be credible to another engineer.
