From ceramic pigments to high-strength machine-readable codes - The technology elements of Ceracode
The Ceracode technology concept is an integrated solution consisting of a temperature-resistant ink using drop-on-demand industrial printers and an intelligent maintenance concept. Ceracode enables the design of efficient and quickly implementable solutions for part identification in metal processing.
Industrial-suited inkjet printing and code recording in the process
Industrial inkjet printers (so-called Drop-on-Demand printers or DoD printers) are used to apply the ink as a machine-readable Data Matrix Code (DMC). The print image can be created from individual dots with 16 or 32 parallel jets in the print head.
The use of DoD printers allows a simple integration of the marking systems into the production lines and a fast printing of the parts without losing time in the production process.
The marking is fixed and hardened in the furnace during the hot forming of the parts (or in further high-temperature steps) at more than 800 °C.
Intelligent maintenance concept
A concept for predictive maintenance is also implemented on a controller. The code is scanned with scanners and checked for content and print quality during printing as well as along other production steps in the process chain (e.g. press hardening).
The images are recognized and analyzed with intelligent algorithms (based on machine learning) to evaluate the status of the print image and thus the print head in real time. Deviating behaviours of the print head and fluctuations in code quality are anticipated at an early stage and maintenance interventions can be tailored to the planned downtimes. This enables downtimes to be minimized.
