Digitalization of the process chains

The combination of Ceracode ink and the data matrix code, which is widely used and standardized in the industry, gives a new boost to the digitalization of production processes in metalworking sectors. "The quality of every component or workpiece can be recorded at any time along the value chain and errors can be detected and rectified right at the start of production. In this way, companies not only save energy, they also avoid wasting raw materials and reduce their_{CO2 emissions}," explains Härtling. Overall, production becomes significantly more efficient and cost-saving. The process data stored in the database also makes it easier to set up adaptive process chains. If a manufacturer knows which physical parameters were used to manufacture a product, they can flexibly adapt and optimize subsequent work steps and processes.

Depending on the application scenario, the database can be filled with additional information as required. For example, data on power consumption and the power source could be included for each processing step and then used to calculate the greenhouse gas emissions for each component. "More and more manufacturers are requesting such features in the interests of transparent and resource-saving production," explains Härtling.

Data exchange via Catena-X

In addition to optimizing production, the technology from Fraunhofer IKTS also paves the way for an even more comprehensive exchange of information between manufacturers, suppliers and subcontractors. In the automotive industry, these are already linked by a complex network. In future, this exchange is to be realized by the Catena-X network platform, which is currently being set up. As a cooperative data ecosystem for the automotive industry, it is intended to enable the secure and uncomplicated exchange of data between manufacturers, while at the same time guaranteeing each participant sovereignty over their own data. The participating companies therefore only exchange the data that they actually want to disclose.

With Ceracode, detailed information on the process parameters of metal components can now also flow into the Catena-X network for the first time. Here too, data that the manufacturer does not wish to pass on, such as internal details about the manufacturing process or the material composition of a component, remains protected in the company's internal network.

Forgery-proof with Ceracode

The solution is primarily aimed at customers in the metal, automotive and ceramics industries. Manufacturing companies can easily install and commission the system, and retrofitting existing machinery is also no problem. The Data Matrix printers and scanners are compatible with existing industry standards.

In addition, the ink technology can be largely adapted to the customer's needs and application scenario. One example is the protection of products against counterfeiting. "For this purpose, we supplement the formulation of the ceramic-based inks with special pigments that glow in a defined color under UV light. This is an interesting option for industrial customers who purchase parts with particularly expensive metal alloys or components for safety-relevant systems," explains Fraunhofer researcher Härtling.

In the next step, the project partners Fraunhofer IKTS and Senodis Technologies are working on optimizing the image recognition algorithms so that the marking can be applied to other materials and irregularly shaped surfaces.
