In world class manufacturing today, the result of shipping a defective part can be  atastrophic. The NDT-RAM Resonant Acoustic Method systems — per ASTM E2001-13 — are designed to fully inspect parts, economically and on time, giving you and your customer confidence in part quality. Our range of systems can help you meet your goals no matter what the environment.

The principle of NDT-RAM is simple. Every part has a unique resonant signature that reflects its composition. Any deviation from the expected signature indicates the presence of a structural flaw or variation. A familiar example is a cracked bell that no longer has a clear ring and cannot hold its tone.

With no part preparation required, this technique can objectively identify resonant frequency shifts caused by internal and external flaws due to cracks, voids, material density, brazing integrity and missed manufacturing processes, eliminating errors that come from human interpretation. The entire procedure takes only seconds per part, allowing for efficient quality control testing of all the parts in your process line.
