₂In the beverage sector, it is common for bottling plants to require coding and labelling systems that can mark 70,000 to 90,000 bottles per hour, depending on the material. Reliably printing 2D codes at such high speeds can be a huge challenge, and in the past, manufacturers have had to slow down production lines to achieve the required quality. The Dx Series CO₂ lasers have been developed to help beverage manufacturers meet the increasing code requirements. A new coding algorithm enables up to 30 per cent faster coding to achieve the required speeds - with low substrate load and without compromising code quality. The Dx series lasers are robust and resistant and are suitable for the challenging temperatures, humidity and condensation often found in bottling plants. The CO₂ lasers are designed to operate in temperatures of up to 45 °C and feature an IP55-certified controller and an optional IP65-certified printhead variant (standard IP54-certified) for additional protection against the ingress of dust and water. The entire range of laser marking systems is available with a new range of laser extractors to remove dust and vapours to ensure marking quality and increase the life of the laser equipment. The Dx Series lasers have been designed with flexible beam guidance and customisation options so they can be mounted in any orientation to apply variable data to the neck, side or base of beverage bottles during production. The Dx series includes the Dx260i (20 watt), Dx360i (30 watt) and Dx660i (60 watt) models and offers options for different materials and code requirements. The 20 and 30 watt solutions are suitable for printing labels, pouches and bottle corks, while the more powerful 60 watt solution is suitable for high speed coding on PET and glass as well as large format, complex code requirements, for example replicating the contents of entire labels to support the move to label-free bottles.
