Marking laser systems in high-speed manufacturing lines create serial content such as shelf life or production data. Other marking contents with a purpose beyond classic product identification are logos. In any case the high speed of the laser system is always a prerequisite for integrating it into production.Read More
Silvia Rosenberger, Technical Marketing Manager at Merck KGaA, Darmstadt Germany, held a lecture as part of the FOBA “Virtual Manufacturing Day 2020” webinar series on January 14, 2021. As an expert for laser pigments, she explained together with her colleague Stefan Gutberlet, Global Marketing Manager Industrial Pigments, how plastics can be optimized for obtaining best laser marking results.
During the webinar, which attracted many participants, numerous questions came up which could not all be answered due to limitations of time. Therefore, as a webinar follow-up, Silvia Rosenberger and Stefan Gutberlet kindly provide their missing answers for the FOBA blog.
The webinar recording “Lasermarking of polymers and the improvement through laser pigments” from January 14, 2021, is available on demand at https://page.fobalaser.com/FOBA-WBN-VMD-Merck-2020-EN_WBN-LP-OnDemand-EN.html
Just in a nutshell: What is the benefit of using laser pigments?
Stefan Gutberlet: Customers either ask for an improvement in speed or in marking quality. So, we say: Once the lasers become faster, the material must keep up with it. And this is what our pigments do. They improve the marking speed, the contrast and the line definition with pulsed DPSS or fibre lasers in polymers. Without laser pigments most polymers do not contrast mark at all.Read More
A great number of medical applications, many of which require direct part marking for device identification purposes, are made of plastics. Since lasers can create durable and high-quality marks, laser technology is the proven method for plastic marking.Read More
The first Virtual Manufacturing Day 2020 on November 24 is a virtual trade show for manufacturing companies from the automotive, medical or electronics industries. The focus is on automation solutions specifically for product tracking. The exhibitors are showcasing innovations in optical quality control, robot-supported production, analysis and diagnostics, in the application of materials such as metal or plastic, and in laser marking.Read More

The FOBA Y.0200-xs fiber laser marking system can be integrated into any production line thanks to the smallest marking head available on the market. Field-tested, Titus™ achieves top marking results, as demonstrated by application testing on colored plastic profiles.Read More
Glass is best marked with UV or CO2 laser systems. The energy input can be kept low to minimize the effect of microcracking.
Both marking methods create easily readable and resistant characters by means of engraving or colour change, which are optically different on closer inspection. While the UV laser marks are even, finely rasterized areas, the resolution of the CO2 marking appears in coarser pixels.Read More
Titanium is a high-quality material that is used in (dental) medical technology for implants, in the automotive sector for screws or valves, and for many other applications. It is usually marked in black by laser annealing, while colored laser markings are possible but less durable.Read More
