Laser marking plastic additive.

The wavelength required for this around 1064 nm can be generated by three different light or diode pumped laser systems the neodymium yag laser the neodymium vanadate laser and the fibre laser. The laser marking procedure enables permanent markings to be made on plastic surfaces with a visually controlled laser beam. As laser marking systems become more advanced and gains importance in today s manufacturing sector among other areas the need for ability to mark polymers continues to grow and it s applications like plastic parts security seals. Beam steered ytterbium fiber lasers and predecessor nd yag lasers arc lamp and diode pumped operating at 1060 1080nm near infrared possess ideal waveguide properties specific to their.

The components made from these molding compounds ensure good laser weldability of two transparent materials and for laser marking dark lettering of the highest quality even for highly trans parent and colorless plastics. Direct ink printing puts an image on the surface of the plastic which can be removed by abrasion or solvents but laser marking can provide an indelible high contrast mark in the material itself with no direct contact with the plastic other than through the incident laser beam. These advanced material science formulations achieve unprecedented marking contrast line edge detail and speed on plastics that have traditionally been difficult if not impossible to laser mark. It is a highly.

The newest generation of laser marking smart additives incorporated into polymers is a quantum leap in technology which is both enabling and cost saving. Information is typically in the forms of alphanumeric text symbols graphics logos schematics barcodes machine vision codes etc. It is not based on mica or another substrate and therefore it does not impart a pearlescent grainy or reflective appearance. Laser marking is fundamentally different from ink printing the traditional method of marking on plastics.

At brilliance we specialize in laser marking materials and additives and have developed the newest compounds to improve laser marking technology for plastics for today s market. It is a patent protected high efficiency nir absorber based on modified tungsten oxides. Material optimisation with 2 3 addition of laser additives is often essential for achieving an optimal marking contrast. It can be easily dispersed in polymers as well as liquid colorant systems.

This creates a dark mark obtained from the burning or charring on the surface or a light mark obtained when the laser causes the polymer to foam. Irasorb cto m10 by keeling walker is an infrared filter and laser marking additive. The l tec additive works by absorbing the laser energy and causing some very localised heating for a very short time. Sharp markings can be made on transparent or light colored plastic parts with an ndyag laser creating a mark that is heavy metal free and suitable for food contact applications.

Both light and dark marks are permanent and resistant to light abrasion and chemicals. Mark it by basf is an antimony doped tin oxide. Laser marking of plastics is a noncontact digital process whereby indelible information is applied onto a target substrate surface with minimal material penetration.
