Laser marking technology
Laser technology: a cutting edge solution for marking !
Part traceability is essential for compliance with ISO quality standards. Laser marking allows manufacturers to automate marking operations and ensure a high level of control.
The laser technique consists in generating a beam from a laser source, amplifying it and directing it to the part via mirrors. The reaction induced inside the material results in 3 distinct processes:
· Engraving : create a groove in the layer
· Annealing : change the color of the target material to enhance contrast
· Foaming : change the coating aspect
Different types of laser exist
- CO2 lasers are dedicated to mark on glass or other transparent objects,
- Yag lasers are best suited to metal applications but remain costly over the course of time,
- Fiber lasers are dedicated for marking on metals and plastic, when power is required
Fiber Laser performance
Fiber laser marking is the most efficient technology. The laser signal is generated by the laser source and amplified in the optical fiber cable. Then, the signal goes through the collimator which aligns the beam and reduces its diameter to 7mm before entering the galvanometric head. The Galvo head is equipped with two mirrors which direct the laser beam for fast and precise marking. Finally, a lens concentrates the signal power into a 30 µm beam. SIC Marking has chosen the Ytterbium-doped fiber laser for its reliability, power and low operating cost.
Laser marking applications
Laser is primarily used for direct marking on metal or plastic parts regardless of hardness or surface textures. Laser is recommended for high-volume production, where speed and accuracy are essential.
Lasers are widely set up on production lines, in automotive, aerospace, mechanical, medical and surgical, oil and gas industries,and more.
Main characteristics:
- High end technology,
- Reliable,
- No maintenance required,
- Durability,
- High definition marking.
Fiber laser i 103 lg
Our integrated laser system is built around a small marking head which is easy to integrate whatever the position. The laser i103 l-g offers a 100x100mm marking window. The head is controlled by a complete command rack which includes laser source, board and security loops. This laser is mainly set up to operate in a stand-alone mode (like a black box), connected directly to PLCs. You can configure
the laser to work from a PC through dedicated software. The "Fiber Unit" rack is able to manage up to 4 axes.
Fiber laser c173 lg
Our table-top laser system is built around the same marking head as the i103 l-g. The laser c173 l-g offers a 170x170mm marking window. The head is controlled by a complete command rack which includes laser source, board and security loops.This laser is mainly set up to operate in a PC mode through dedicated software. The "Fiber Unit" rack is able to manage up to 4 axes. C173 l-g can be customized with a wide range of options, such as automatic z axis, rotary axis, fume extractor and many more.
