Semi-Automated Non-Destructive Test Resonant Inspection System

For Production Line Integration | RAM-TEST-SEMI

Resonant Acoustic Method is a non-destructive testing technique helping to deliver 100% quality-inspected parts quickly and economically. How does resonant inspection work? Each part has a unique resonant signature that reflects its composition. Any deviation from this signature represents a structural variation. Non-Destructive Testing Resonant Acoustic Method (NDT-RAM) uses this principle to objectively discern between small differences in complex parts.

  • Clean - no part preparation or messy chemicals are needed for testing
  • Adaptable - to existing process automation
  • Durable - NDT-RAM systems have been running 24 / 7 / 365 in the plant environment for over 20 years
  • Backed by Experienced Service Staff - With 20+ years of industry and application experience, we are here to support you

Applications

  • Powdered Metal
  • Castings
  • Forgings
  • Metal Stampings
  • Ductile/Gray Iron
  • Ceramics
  • Composites
  • Additive Manufacturing
  • Braze/Weld Joints
  • Metal Injection Molding (MIM)

RAM-TEST-SEMI can be tailored to match your specific quality inspection needs. The RAM-TEST-SEMI system is designed to fit into an existing production line and is flexible enough to test a wide variety of parts. An industrial impactor “pings” (taps) each part with a measured and repeatable force, producing sound. A microphone then transforms the sound into an electrical signal sending it to a digital controller to determine frequency characteristics. NDT-RAM software compares those characteristics to criteria limits and accepts or rejects the part. The system interfaces with programmable logic controllers for easy integration into an existing production line.
