Free Parts Evaluation Using NDT Methodology

THE MODAL SHOP, INC.’s free parts evaluation program determines feasibility of quality assurance testing via the Resonant Acoustic Method (NDT-RAMTM) for powder metal, cast, forged and stamped parts.  The parts test allows manufacturers to send a small set of good and bad parts in for feasibility testing by The Modal Shop’s experienced NDT engineers and receive a detailed written report on the results prior to any capital investment.

The trial parts testing is an ideal way for manufacturers to explore in-line quality assurance via resonant inspection at no cost.  The benefits that can be realized from a successful parts test and installation of an NDT-RAM system include fast 100% inspection of parts prior to shipment to remove human interpretation errors from the quality assurance process, and having a de facto process monitoring system in place that objectively measures part quality on 100% of the parts.  It also can eliminate quality related recall and resorting expenses and reduce scrap costs by minimizing false rejects.  With no part preparation required, this technique can successfully identify resonant shifts caused by internal and external flaws such as cracks, voids, material density, dimensions, bonding and missed manufacturing processes.

In addition to free parts evaluations, The Modal Shop also offers NDT-RAM system rentals and no cost financial justification studies as part of a complete NDT-RAM qualification process that lowers the risk of trying the technique:

  • Free parts evaluation – technical feasibility
  • System rentals – production feasibility
  • Financial justification study – financial feasibility
