X-ray CT Scanning

Looking for high flexibility in dimensions, resolution and accuracy? With our current Metrotom 6 Scout, all this is perfectly possible. We can assist you with porosity analyses, mapping internal defects & hidden features and quick visual inspections.

General

Micro CT scanning is a non-destructive testing method that allows internal material inspection. This for both high-performance industrial plastics and light metals.

This measurement principle makes it possible to map process changes on the one hand, and to detect a lot of other information on the other. These include:

Hard-to-reach zones
Internal cavities and defects
Possible obstructions
Complex assemblies
Different materials (with different density)

Internal defects & Hidden features

Seemingly simple products are often more complex than imagined. Parts can have deep ‘pockets’ and complex (internal) geometries.

All this data can be captured using CT scanning. So the great advantage of CT is that it can capture areas that are difficult to reach with more traditional equipment.

CT scanning: A non-destructive testing method where you can always obtain 100% data.

Serial measurements

A major advantage of CT scanning is that it does not need to be done individually per part. Multiple (smaller) parts can be scanned simultaneously so that measurements can be made in a cost- and time-efficient way. This can be interesting at different stages within the production process, for example:

Golden samples
Mould inspection + Pre-production inspection
SPC (Statistical Process Control)
Final inspection
…

Quick visual inspection

The actual to nominal comparison option allows a very quick and visual check. Deviations between the physically produced part compared to the CAD data can be seen at a glance.

Furthermore, it is also possible to carry out a small series control and compare pieces with each other. One of the reasons why this technology is so popular within injection moulding.

Moulds can be adjusted, materials can change,… the smallest (process) change can have a major impact on the end result.

Porosity analysis

Process validation of 3D printed parts often requires a porosity analysis.

CT-scan data can be used to analyse the internal structure and draw conclusions regarding:

The (possible) leakage and gas/air tightness of the component.
The production process consistency
The product durability
…

Assemblies

Because of the structure of a part, it is often not possible to demount it for quality control. Again, CT scanning offers a big advantage in comparison to other measurement methods. Consider checking:
