The process could also be used to increase flexibility and efficiency in the industrial production of other medical technologies
Nickisch was previously Key Account Manager for the expansion of the systems business at the machine manufacturer Evosys Laser GmbH and has been involved in laser welding of plastics for more than a decade
The masterbatches are cost-effective and enable high-definition, high-contrast laser marking on clear and dark surfaces using NdYAG laser systems
The new design is both lighter and easier to wear than a previous design made using acrylic.
Laser system manufacturer Trotec has successfully developed a face shield that can be laser cut from a single sheet of PET plastic
