Resonant Inspection Perfect for MIM Medical Component Inspection

THE MODAL SHOP, INC.’s Resonant Inspection nondestructive test systems are ideal for 100% quality assurance testing for manufacturers or users of Metal Injection Molded (MIM) parts in the medical device industry.  The NDT-RAMTM (Resonant Acoustic Method) systems have proven effective for reducing liability and increasing confidence in zero defect shipments at major medical device manufacturers as an in-line quality inspection solution.

In contrast to the common x-ray, imaging, scanning, and dimensional testing of MIM medical device components, NDT-RAM tests the whole part, internally and externally, to alert of anomalies and structural flaws in components and is covered by the ASTM E2001-08 standard.  Whole part testing is a valuable tool in screening for subsurface cracks or micro fractures.   The entire process can be achieved as fast as one second per part, allowing for efficient, production speed quality control testing of all parts flowing on a quality production line.

NDT-RAM works on the principle that every part has a unique vibration signature (resonant frequencies).  These resonant frequencies will have little change from good part to good part.  However they will shift when there is an internal or external change in the part from manufacturing variance or imperfection in the part.  For example, when a bell has a crack, it doesn’t have a clear ring, and loses its ability to hold its tone.  The same is true of a part that has a flaw.  Adding to the NDT-RAM method, an innovative Drop Test Fixture makes automated testing of small parts easy.

Free parts evaluations are offered for feasibility testing of parts and system rentals are available allowing NDT-RAM to be evaluated in the factory before buying.  Following a commitment to simple, reliable and affordable quality assurance, the system can be used to test parts with less than a day of training after the system is installed.

Significant trade-in credit is available for customers with aging or complicated competitive systems.  For free parts testing, specification sheets, application data, competitive product upgrades, pricing or to schedule a rental or demonstration, please contact THE MODAL SHOP, INC., 3149 E.
