Assesses Nodularity in Ductile Iron Cast Automotive Components

  • Ultrasonic velocity measurement provides an industry accepted, reliable means of testing the integrity of automotive parts.
  • Echomac®VM evaluates velocity, thickness or flaw detection.
  • Operates with either full immersion or bubbler couplant technology.
  • Enables the testing of two parts simultaneously–from separate test stations—using only one instrument.
  • Standard configuration features two channels for Velocity and two for Flaw testing, with the option to add four additional Flaw channels.
  • Industrial hardened I/O connections are protected from the environment.

Variations in Nodularity, a type of graphite structure that can develop during the production process, can attenuate the velocity of sound waves passing through the automotive component being tested.  Echomac VM measures the sound velocity and, using known limits, reports whether the part is acceptable.
