Identification of laminated components:
Definition and application

In the manufacture of components, semi-finished products and products, various production processes are frequently run through. Continuous component marking forms the basis for complete traceability of components and the targeted optimization of process parameters. Particularly in harsh process environments, consistent marking of individual components is often difficult or impossible to implement with current marking solutions. With the help of the CeraCode marking solution developed by Senodis, these problems can be solved, especially in manufacturing processes with high temperatures of over 900°C, and individual component marking can be implemented.
In addition to harsh process conditions, laminations of surfaces also pose a challenge. Lacquering or chrome plating are common processes, especially in the metal industry, to prevent corrosion or to refine surfaces. To enable continuous traceability of components, the codes applied to the components must still be reliably readable even after such surface lamination processes.
To make this possible, Senodis uses optical methods such as shape-from-shading. With the aid of targeted exposures of the components, e.g. from all four sides, gray-scale images of the components can be created and topographies determined. These topographies allow codes applied to the components to be reconstructed and read out again. Senodis thus closes another gap in component tracing and enables process optimization even after lamination processes.
