Exact Metrology Performs Bulk Plastic Cap Inspection

Exact Metrology, a comprehensive 3D metrology service provider and hardware sales company, performed a recent inspection on molded caps to showcase the power and capability of multi-part inspections at its Brookfield, Wisconsin office.

Computed tomography (CT) scanning is an x-ray methodology yielding 3D results by placing an object on a rotational stage between an x-ray tube and an x-ray detector, rotating the object 360 degrees and capturing images at specific intervals.

To render the 3D x-ray model of the object or part, the series of images is reconstructed. CT visualization software can reportedly slice in any direction to produce optimal views and images required for the analysis of internal configuration and instant CAD comparison. This software can segment multiple scanned parts, creating individual files for each component. These can be analyzed independently, and all statistics can be evaluated.

The GOM CT scanner used by Exact reportedly enables the inspection of complex parts based on volume. It produces the finest details visible throughout the component, simplifying initial sampling, tool correction and inspection tasks during production. It captures complex components including the “inner workings” in a single scanning process, so that the user receives a complete image of the test specimen for form and position analysis or nominal/actual comparisons.

This scanner reportedly features a 225 kV X-ray source and a high-contrast 3k X-ray detector that generates a very fine pixel grid, laying the foundation for high-precision detection of the measured components. 5-axis kinematics with an integrated centering table reportedly make it easier for the user to position the component optimally in the measuring volume.

Additional features reportedly include temperature balancing for metrology applications, an I/O port and photogrammetric calibration. Within the measuring volume several objects can be measured simultaneously in one scan, reducing processing times. Thanks to the proven GOM technology, the CT ensures high precision and repeatable measurement results.

As with all GOM metrology systems, the control of the device, data acquisition and evaluation are combined in a single software package. This means no additional software is required.
