Non-Destructive Small Part Quality Test System – NDT-DTF

The Drop Test Fixture, Model NDT-DTF Resonant Inspection System, allows automated sorting and quality testing of small metal injection molded (MIM), powder injection molded (PIM) and other small parts by using the Resonant Acoustic Method (NDT-RAM).

The NDT-DTF 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.
