Resonant Acoustic Method (NDT-RAM) Perfect for Powder Metal

THE MODAL SHOP, INC.’s Resonant Acoustic Method Nondestructive Test (NDT-RAMTM) systems are ideal for quality assurance testing for manufacturers or users of powder metal parts in a variety of industries, including automotive, aerospace, and consumer goods, such as lawn and garden applications and rotating laundry equipment.  NDT-RAM has proven effective as on in-line solution for many powder metal 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 due to cracks, voids, material density, brazing integrity and missed manufacturing processes, eliminating errors that come from human interpretation.  The entire process can be achieved as fast as one second 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.  Free parts evaluations are offered for feasibility testing of your parts and system rentals are available allowing you to try the system in your factory before buying.  The system can be used to test parts with only a single day of training after the system is installed if parts have already been evaluated at our facility.

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:
