Semi-Auto Non-Destructive Quality Test System – NDT-SEMI

Resonant Inspection for Integration In-Line

Resonant Acoustic Method is designed to help deliver fully inspected parts, economically and on time.  Every component has a unique resonant signature or pattern that reflects its composition. NDT-RAM™ detects deviations from the expected signature or pattern. The NDT-RAM Semi-Automated System is the ideal system for easy integration into an existing production line.  The system includes all of the core components of NDT-RAM, including the smart digital controller, industrial impact hammer, microphone, software and industrial PC.  The system can directly interface with any programmable logic controller and become an integral piece of your existing quality inspection system.


  • Versatile- multiple part numbers can be used on a single system
  • Clean - no part preparation or messy chemicals are needed for testing
  • Simple - pass/fail result is returned by the NDT-RAM system
  • Adapts - to existing process automation
  • 100% Inspection - test every part prior to shipment

All of the NDT-RAM systems are ideal for 100% inspection requirements of manufacturers or users of powder metal, metal injection molded (MIM), castings (including ductile iron), forgings, stampings or welding.  NDT-RAM provides screening for cracks, chips, holes, porosity, out-of-tolerance dimensions, variations in hardness, residual stress, bonding failures and heat-treating processes. Manufacturers that have significant inspection costs (either material or labor costs), produce or use safety-critical parts, have substantial scrap costs due to false rejects or simply want to improve their part quality can benefit from NDT-RAM technology.
