Marking solutions for hot formed metals parts
High process temperatures in the production of metal components prevent individual component marking. In the temperature range up to 1200 °C, standard methods for generating machine-readable codes often fail. An individual marking is usually only applied after the temperature treatment, which is why expensive process steps (e.g. hot forming) cannot be recorded. This results in high rejection and sorting costs as well as an incomplete process documentation.
Senodis provides an all-in-one solution for creating a high-temperature-resistant marking and recording of components along the process chain. With the help of the CeraCode® technology, customers get a machine-readable, up to 1.200°C heat-resistant and individual component identification, component tracking and process data acquisition in metal processing.
CeraCode® – New ceramic based marking solution
Components are printed with a heat-resistant ceramic ink which is optimized for the adhesion to metal surfaces. The ink is printed on the component as a machine-readable data matrix code (DMC) using standard industrial printers. The printing is realized without delaying the production process. The code is recorded with scanners after printing as well as along other production steps in the process chain and its content and print quality is verified. The scanned data is transferred to the customer's data room via the data interfaces provided. A controller unit handles both the data handling and the control and monitoring of all system components.
With the help of this identification, process parameters can be linked to the individual components and high rejection and sorting costs can be avoided.

Digitization in hot forming
Also, in metal processing the requirements for individual marking of parts and products (direct part marking) are growing with the increasing digital recording of production processes. Essential steps to optimize manufacturing processes and their quality assurance as well as additional digital value creation and business models can only be implemented with a complete component recording and tracking.
Missing individual part marking in the hot forming
Current marking solutions usually do not fulfil the special requirements in metal processing. The rough production conditions (e.g. high temperature, chemical exposure), which regularly lead to the destruction or illegibility of the marking, represent a major challenge that has not yet been resolved. In addition, many machining processes are carried out between 700 °C and 1200 °C, where conventional marking processes usually fail. A special need for continuous marking and recording of the individual parts arises with press hardening, a cost-optimized process for the production of high-strength lightweight components made of steel or aluminium.
If a marking cannot be applied or can only be applied late in the process, this hinders the component-resolved recording of all previous steps. Setting or influencing parameters can then not be linked to measurement and test results of individual parts, which results in high rejection and sorting costs as well as an incomplete process documentation.
Ceracode — new paths for the tracking and tracing of metal parts
With Ceracode, Senodis closes these information gaps in the process chain. Defective parts can be recognized individually and in the running process and, if necessary, sorted out without significant manual intervention, which leads to noticeable cost savings. The digital process recording, and monitoring based on the part identification enables an analysis of the data obtained for further process optimization and quality improvement.
Where technological barriers have previously prevented part identification and the recording of process variables, Senodis provides the key to the digital factory with the latest concepts for optical identification, data acquisition and information processing.
