Quick and reliable inspection system
Quality of manufactured parts for automotive industry is key for success in the business. Even a simple thing such as thread can negatively influence the production process if it is not made properly.
If it is the assembly process or the robustness of the joint that it provides, reliable inspection of threads is a must for critical components in automotive industry such as engine castings, wheel bearings and other. Moreover, understanding the real parameters of each production process is a key to control it. IIT is the best system giving you all of this in a single package.

Measurement method description
The inspection system consists mainly from a capacitive probe with toroid measurement field, special fixture for centering of probe, amplifier to process the signal and control unit to evaluate the readout and make quality decision.
The probe is inserted into the thread and an equidistantly synchronized signal is captured. It is further processed to detect any deviations from the expected waveform. Various features (not only thread) can be evaluated from the readout. System provides calibration and teach-in capabilities, online visualization and statistical processing, storage of data about rejected parts and other data processing functions.
The options of integration the contactless thread inspection into serial manufacturing process depend on the cycle time and material process flow.
It is also possible to integrate other types of inspection such as camera system or 3D measurement of parts into the same station for higher added value and ROI.
- Standalone automated machine with feeders (for small parts)
- Multiple-probes single purpose high speed inspection station
- Robotic station (for flexible solution with many inspection points)
- OEM components for further integration into existing equipment
