In-Trace – Validation of an intrinsic component identification system

Objectives and Approach

The objective of the project is to validate electromagnetically detected intrinsic material characteristics (known as “material fingerprints”) as permanent object IDs that can be used across the entire process chain. As part of the “In-Trace” project, the object IDs will first be tested on an industry-oriented laboratory demonstrator and subsequently in an industrial pilot application for the use case of a cold forming process chain in automotive body construction. The goal is to demonstrate that, even under typical production-related disturbances (such as lift-off variation, temperature drift, tool wear, and plastic deformation of components), a recognition rate of nearly 100 percent can be achieved with a measurement time of less than 0.5 seconds per component.

Innovations and Prospects

This solution offers brand protection through a scalable, inline-capable, and forgery-proof traceability system. It cannot be copied or added retroactively, eliminating the need for external markings such as barcodes or labels. The material fingerprints are derived from the area near the edge of the component’s interior and can be captured repeatedly even after machining or covering of the surface, allowing the component to be identified even after forming, grinding, or painting.

This innovation can be applied in a wide range of industries, such as casting, forging, and additive manufacturing, and is of interest to both manufacturers and suppliers. Plans for commercialization include licensing the patent or establishing a spin-off company.

In-Trace is a collaborative project involving Fraunhofer IZFP (coordination), Fraunhofer ITWM, and Fraunhofer IWU.
