The principle of NDT-RAM is simple. Every part has a unique resonant signature or pattern that reflects its composition. Any deviation from the expected signature or pattern indicates the presence of a structural flaw or variation. An example is a cracked
bell that no longer has a clear ring and cannot hold its tone.
RAM-DROP automates easily with typical small part automation components like bowl feeders or vibratory tables and is instrumented with a laboratory grade force sensor, microphone, and digital signal analyzer while still being rugged enough for
the manufacturing environment. This easy-to-use NDT system can detect imperfections or flaws such as cracks, missing features, and mixed parts. It can also detect if processes have been missed, such as a machining or heat treating operation.
With typical throughput speeds of one to three seconds per part, RAM-DROP provides a means for objective sorting that requires no human interpretation. A simple pass/fail result is returned by the system and parts are automatically sorted via a controlled
NDT-RAM systems are ideal for 100% inspection requirements of manufacturers or users of powder metal, metal injection molded (MIM), castings (including ductile iron), forgings, stampings or welding. NDT-RAM provides screening for cracks, chips,
holes, out-of-tolerance dimensions, variations in hardness, residual stress, bonding failures and heat-treating processes. Manufacturers that have significant inspection costs (either material or labor costs), produce or use safety-critical parts,
have substantial scrap costs due to false rejects or simply want to improve their part quality can benefit from NDT-RAM technology.
