CT scanning for product analysis

CT scanning of a tiny technical plastic part reveals air inclusions

Sonion A/S develops miniature components for hearing aids, in ear headsets, and communication units.

Problem
The small plastic part "Sonion Tube lock" with a size of 5 mm, was to be analyzed with respect to documentation of air inclusions and fiber structure. Furthermore, part verification and dimensioning should be performed.

Solution
By CT scanning the Tube lock, it was clear that the miniature component contained air inclusions. Additionally, the scanningen documented the fiber structure. Finally, the part was dimensioned using Geometric Dimensioning & Tolerancing.

CT scanning
CT scanning is x-ray scanning in 3D and is also called computer tomography. The technology is ideal for part measurement and material analysis, as both internal and external geometries are documented. Read more
