Laser Marking

 

The Principle

Laser light is monochromatic light with high energy that can mark many materials as plastic, ceramics and more. The marking occurs when the surface is thermally or chemically changed.
 
Several systems exist as CO2, Nd:YAG and Excimer operating at different wavelengths. The most used are CO2 and Nd:YAG. Controlled Polymers are using Nd:YAG.
Dependent on wavelength and the formulation of the plastic the chemical reaction is foaming, carbonation, etching, engraving or photochemical reactions giving colour shift.

We have obtained good results with

ABS              Acrylnitrile-butadiene-styrenes

ABS/PC        Acrylnitrile-butadiene-styrene/Polycarbonates

PA                 Polyamides

PC                 Polycarbonates

POM             Polyoxymethylene - Acetals

PE                 Polyethylenes

TPE               Thermoplastic Elastomeres

PP                 Polypropylenes
