Trumpf has released new additions to its range of TruMark Series 3000 and 6000 laser markers, able to meet the material requirements of a wide variety of plastics by using appropriate laser-active media and different wavelengths. The systems are designed to be directly integrated into automated manufacturing lines and thanks to their small footprint they are ideal where space is at a premium. Open architecture allows quick and easy connection to existing control networks.
New additions to the TruMark Series include the TruMark 3130, suitable for high-precision applications such as day and night designs, such as those found in cellphone keypads and illuminated switches in cars. The new model uses an yttrium-vanadate laser, making it suitable for pulse frequencies of 30-100kHz. In this frequency range the TruMark 3130 exhibits exceptional pulse-to-pulse stability.
In common with all TruMark Series 3000 lasers, the TruMark 3130 is of modular construction. Scanner, laser head and power supply unit with hybrid cable simply plug-in, making integration simple and quick. Plug-in cards facilitate easy expansion of the control system and, in comparison to the previous series, this new generation consumes about 80 per cent less power. Thanks to an integrated cooling system it can also operate under ambient temperatures of up to 40°C.
Another new addition is the TruMark 6330, the UV laser of which makes it suitable for marking flame-resistant plastics. This model features a dual laser-head system, able to mark at 2,800 characters per second with a single-line font of 1mm character height. The system also features adjustable power distribution and independently calibrated scanner-heads.
