In solid forming, in addition to the high process temperatures, the high degrees of deformation also pose a challenge for component marking. Due to the severe deformation, standardized code formats cannot be used. With the ID fingerprint technology developed by Senodis, marked components can be recognized even if large parts of the code are missing. In addition, a unique key can be generated for each component, which enables unambiguous traceability independently of the actual code.
The unique fingerprint for solid forming components includes both marking and identification of components despite high forming temperatures and degrees of forming. For this purpose, image recordings of applied component markings are generated and individual details of the marking are examined using digital image processing. These can include position deviations, contrast differences or the smallest irregularities. These features can then be used to form a so-called hash value, which represents a unique identification of the component. If only parts of the original marking are still present after further production processes, this technology can be used to infer the original marking and thus the component number. This ensures traceability even after partial destruction of the marking. In addition, this process represents a further security feature, as markings printed several times with the same code content can also be distinguished.
- Additional security feature and unique component identification
- Independent of standardized code formats
- Identification even at high degrees of deformation and temperatures above 1300°C
- Pattern recognition via individual image features
- Traceability and data exchange throughout the entire process chain
In addition to pure, customisable component identification, intelligent camera modules can be installed along the entire process chain. This makes it possible to re-identify components and assign process data. It is also possible to link several of these stations together along the supply chain to transfer specific component and process data.
Classically, high-temperature inks are used for marking in the high-temperature range. However, this technology also offers the possibility of using other marking methods that may already be available to the customer, like laser marking, embossing units or punching processes. With the help of Senodis’ optical recognition methods, all common markings can be used to generate an ID an to trace components worldwide.
The individual fingerprint of each component enables holistic process optimisations and savings through quality improvements, among other things. In addition, digitalisation potential can be tapped through data exchange across company boundaries. Senodis provides various software solutions tailored to the customer in the areas of Industry 4.0, CO2 tracking and circular economy.
Depending on the labelling solution, both integration and ensuring regulated continuous operation are offered by Senodis. In addition to training concepts, Senodis also offers immediate service and remote maintenance concepts. In the digital area, customer requirements can be individually integrated depending on the requirements, ensuring uninterrupted operation of the technologies and products.

Application example: Production start-up (testing of start-up parts)
When the furnace is put back into operation after a planned or unplanned downtime, the parts that leave the furnace first are especially tested and often sorted out. Senodis ensures that start-up parts can be reused directly, if necessary, and ...
Application example: Internal quality complaint
Tests during series production are elementary pillars of quality assurance. From time to time, specification deviations occur that call the component quality into question. To avoid mixing with good parts and to be able to precisely isolate ...To the use case
