Resonant Acoustic Method (NDT-RAM) Ideal for Testing for Nodularity in Ductile Iron Parts

THE MODAL SHOP, INC.’s Resonant Acoustic Method Nondestructive Test (NDT-RAMTM) systems are ideal for quality assurance testing for manufacturers or users of ductile iron parts in a variety of industries, including automotive and consumer goods, such as lawn and garden applications.

With no part preparation required, this technique can objectively identify resonant frequency shifts caused by nodularity. Other internal and external flaws such as porosity, cracks, voids, material density, and missed manufacturing processes are also identified, eliminating errors that come from human interpretation. The entire process can typically be achieved as fast as approximately three seconds per part, allowing for efficient quality control testing of all parts that come off of your production line.

NDT-RAM is an ideal tool for the desire to achieve "zero defects" and eliminate quality related costs such as sorting and recall expenses. A free parts evaluation is offered for feasibility testing of your parts and system rentals are available allowing you to try the system in your factory before buying.

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. Kemper Road Cincinnati, OH 45241-1516, Internet:, (800) 860-4867, Fax (513) 458-2172 or e-mail:
