Trumpf TruMark 6350’s UV wavelength marks plastics, glass and organics

Manufacturers of automotive and electronic parts will be the main beneficiaries of the introduction of the TruMark 6350, says Trumpf, as their products are often housed in flame retardant cases made from thermoplastic engineering polymer – such as PBT GF30 – and fibreglass-reinforced polyamide. Glass marking is another target application. The high average power of the system allows high processing speeds to be achieved without compromising the clarity of the laser mark. This makes it suitable for automated, volume manufacturing and extends the potential for customisation and personalisation. A dual head version is also available for even higher productivity. High quality marks can be achieved without the need for laser-sensitive additives in the substrate. As the process has minimal effect on the substrate, it can be reliably used on more sensitive materials, such as leather and even organic items, like apples. This system features Trumpf's latest generation UV unit which it says has superior life expectancy. It is also easy to integrate via a single umbilical. The 6350, like all Trumark systems, is available in different power output classes and pulse durations so that the optimum solution can be specified for the task.
