What it is :
The laser marking is an heating process, generated by a bright beam (Laser) amplified and localized. This beam impacting on a surface, modifies it permanently.
It is possible to make three different types of marking : the refreshment that creates an heating-generated permanent marking, without damaging the material; the engraving that creates a direct, resistant and long lasting marking; the ablation, that removes the painted layer or the superficial facing, to create a contrast without damaging the material.
Operating principle :
GALVOTEK laser markers of BERMA MACCHINE it is equipped with a galvanometer scan head, coupled with several types of lasers, depending on the specific marking requirements. They can mark alphanumeric texts, images and 1D & 2D codes like Data Matrix (ECC-
They can finally replace less effective systems, which produce a less durable marking.
GALVOTEK markers can be divided in two families, depending on the laser safety class :
