Non-destructive testing

None of the technologies that our team offers, involves any physical contact and they are all, therefore, non-destructive. With the benefit of tomographs of differing capacities from 140KV to 450 KV, we are in a position to measure, analyse and quantify the internal characteristics of parts.

Principal applications of non-destructive testing :
  1. Material integrity analysis
  2. Dimension checking
  3. A range of intrusive analyses
  4. Quality control
  5. Densitometry

1. Material Integrity analysis

Material integrity analysis involves finding faults, cavities, areas of porocity, cracks or other anomalies which can occur in the materials used to manufacture components and products. We can achieve a degree of accuracy ranging from to within +/-1 micron to +/- 0,5 mm using non-destructive testing technologies to identify anything which detracts from the quality of your parts and components.


Material integrity analysis can, for example, identify networks of porocity as the source of leaks or there again, cracks located in areas of mechanical stress :

Examples of possible applications include :
  • Analysis of a pump body
  • Analysis of a six-cylinder engine head (Aston Martin)

2. Dimension checking

We are in a position to carry out a range of dimensional checks using the data generated by the tomograph :

thickness of inner walls, diameter, radius, size of an anomaly, distance between two points/inner walls/geometric characteristics.

As tomography is an intrusive technology, it enables us to test both internal as well as external geometries either in 2D (on native images or IGS contours) or 3D (after a 3D reconstruction phase in "STL" format).
These functions can also be carried out in micro-tomography in the case of very small parts or minute dimensions.


3. Different intrusive analyses

Tomography allows us to inspect natural products, works of art, or archeological artefacts without damaging them in any way. The rich resulting information can be processed in 2D or reconstructed in 3D "STL".

4. Quality control

Quality control makes the following construction process possible :

Assembly/positioning of assembly inserts of different materials.

We are equally able to compare parts made by different suppliers, or parts which have been modified, in order to ascertain the impact of such modifications. Testing parts known as «  first article » fits perfectly into this category as it provides a means of checking their dimensional characteristics with the aim of verifying the effectiveness of the production process. In this way, we can highlight core offsets, thin walls which are « too thin » or other assembly anomalies.

Some examples of possible applications :
  1. Quality control of collectors for gas generators (spria).
  2. Damage monitoring (a part going through a number of stages of fatigue or deterioration).
  3. Machinery assembly.
  4. Assembly of different materials.
  5. Checking the positioning and/or the dimensions of different materials and/or parts assemblies.
  6. Testing and automatic investigation of very thin walls on a digitised model or native CAD.
  7. Process checking (food-processing industry).

5. Densitometry

Densitometry is the analysis of the density of a composite or carbon-material based product or sample. In effect, tomography enables the creation of density maps with the help of known benchmark densities.
Thus it becomes possible to verify the presence of areas of extreme density in your plastic injections or, there again, to ascertain the areas of your eprouvettes with sufficient density for the manufacture of samples.
