Automated Non-Destructive Quality Test System - NDT-AUTOResonant Inspection for High Volume Production LinesResonant 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-AUTO System is perfect for applying efficient and reliable quality control testing to high volume production lines of powdered metal parts, castings and similar components. The system stands alone and can be moved into any production line. NDT-AUTO is fully automated, requiring no user intervention during testing, for efficient and cost effective 100% part testing.
Benefits

- Objective - ideal for in-line, automated, objective inspection
- Unattended - no operator intervention needed for inspection
- 100% Inspection - test every part prior to shipment
- Customizable - conveyor configuration for a variety of parts

An industrial electric impact hammer strikes parts traveling along a conveyor with a known and repeatable force and a microphone measures the acoustic response from the part. Input force and response spectra are measured by the controller, which digitizes the signal, and performs FFT analysis. NDT software compares results against reference criteria limits and either rejects or accepts the part accordingly.
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.
