Grupo CTT is an authorized distributor of NDT-RAM acoustic resonance inspection systems for non-destructive detection of structural defects.
Acoustic resonance testing is a non-destructive testing (NDT) method used to detect internal defects and variations in density or stiffness within solid components.
By impacting a part and recording its acoustic response, the system compares its resonance signature to a reference baseline. Any deviation may indicate cracks, porosity, incomplete sintering, or structural defects.
A fast, repeatable, and fully automatable technique, ideal for in-line quality control in continuous production environments.
The Modal Shop specializes in acoustic resonance testing systems
designed for 100% inspection without surface preparation or
destructive methods. These systems ensure part integrity and full
measurement traceability.
Fully automated system for high-volume production lines in automotive, foundry, and powder metallurgy applications.
Automated solution for small or irregularly shaped parts. Uses controlled impact and high-precision acoustic analysis to detect cracks and density variations.
Semi-automated system for validation processes, mid-volume batches, or integration into existing test stations.
Configurable workstation for laboratory use or low-volume production. Designed to analyze parts of varying sizes and materials.
Portable or benchtop system for spot testing or development applications. Ideal for engineering environments, prototype validation, and quality audits
NDT-RAM can be applied to a wide range of materials and geometries, including both metallic and non-metallic parts. The method is sensitive to variations in stiffness, mass, and density.
Ferrous and non-ferrous metals:
steels, cast iron, aluminum, titanium, and specialty alloys
Ceramics and composites:
advanced materials used in braking systems, filtration, and structural components
Sintered components:
Compacted or heat-treated parts where porosity and density control are critical.
Cast and molded parts:
discs, gears, connecting rods, engine blocks, and complex geometries.
Machined or surface-treated parts:
where material uniformity and coating adhesion are critical
Hybrid or laminated materials:
applications where layered structures may generate distinct resonance responses.
Grupo CTT supports the acquisition and
implementation of The Modal Shop systems
for laboratory and production environments.
