Resonant Acoustic Method (NDT-RAM) Ideal for Cast 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 cast parts in a variety of industries, including automotive, aerospace, and consumer goods, such as lawn and garden applications.  NDT-RAM has proven effective as an in-line solution for many cast parts manufacturers throughout the global manufacturing chain.

With no part preparation required, this technique can objectively identify resonant frequency shifts caused by internal and external flaws such as nodularity, porosity, cracks, voids, material density, and missed manufacturing processes, 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.  Typically, a system is installed and running within your facility in one day.

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