Damatrix Code Marking
SOLUTION FOR PRODUCT TRACEABILITY
Product traceability using 2D codes as Datamatrix code (DMC) or QR Code (QRC) is now widely used in industry due to its intrinsic advantages. Like the barcode, it helps prevent human error in transcription because it is machine readable. Moreover, it allows the recording of information on a very small surface, 30 times smaller than a barcode. Finally, the Datamatrix code marking allows the parts to be encoded directly and, thanks to significant coding redundancy, it can be re-read even when the marking is damaged.
Datamatrix labeling is then a low cost and versatile technology that fulfill increasing exigence of traceability, not only for finished products but also for each of their smaller components.
As miniaturization and number of parts to be labelled increased, direct marking is steadily increasing. Rather than applying a label or sticker, the use of digital technologies such as laser, inkjet printing, electro percussion or electrochemical marking have evolved to adapt to many materials and shapes.
CERINNOV’s laser marking technology offers a unique solution for 2D code marking directly on a product. In addition to the standard laser marking processes (oxidation of the surface or ablation of a top layer) that CERINNOV proposes for some applications, and that generally gives slightly lighter or darker marked areas, CERINNOV’s proprietary solution enables to get a strong contrast which increases the 2D code quality and readability.
Moreover, 2D codes achieved by CERINNOV’s laser marking technology are highly stable and resist to abrasion, highest temperature, vacuum and chemical aggression.
Last, the CERINNOV’s laser marking technology can be integrated along vision systems and AI systems to correctly and precisely locate the 2D code on complex parts.
CERINNOV’s expertise, developed over 20 years of experience in laser marking for glass and ceramics industries can be applied from test bench to industrial production line equipment.
HOW IT WORKS
CERINNOV’s solution for 2D code marking use a proprietary ceramic ink that is deposed on the product in a first step. Then a laser is used to increase locally the ink temperature and make it spread to the product surface. Excess ink is then removed to make the 2D code appears.
This permanent 2D code can be applied on different type of materials including metal, glass and ceramics, including even those used in technical and exigent application (some examples below).
Marking, traceability and authentication
– Creation of decorative or traceability marking which answers to precise specifications
(colorimetry, chemical resistance, mechanical, thermal).
– Product authentication and fight against counterfeiting thanks to a specific optical tracer
integrated in laser sintering powders. They reflect a unique signature when the optical tracer is excited at a
specific wavelength (developed together with Naomarq).
Functionalization & Melting
– To functionalize surfaces (thermal, dielectric, chemical barrier)
– To reach very high temperatures
– The melting of raw materials
– Energy savings
– High flexibility
Cuts, drills and welding
– Realisation of an organic coated ablation on glass, metal or plastic
– Cutting or drilling glass or ceramics
– Welding glass/glass, ceramic/glass, metal/ceramic and metal/glass by laser sintering of mineral powder
