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.
