What is laser marking?
Laser marking is used as a way of permanent marking the physical item for tracking, either to ensure quality. Rather than using a vibrating or rotating tool for an engraved mark on the item, a high -performance laser is used. Instead, the laser is used to create a shift in the color of the material and create visible, virtually indestructible marks with a minimum real impact on the item.
Most plastics can be marked with laser and the process is used on everything from identification badges to additional pens. Due to its indelible nature, laser marking is the ideal choice for barcodes and other forms of inconspicuous monitoring. How lower costs, this factor becomes decisive for many environmentally conscious society and individuals.
There are three main results of laser marking depending on the affected material and laser used to indicate the item. ShnirinG occurs when the absorbed energy warms the surrounding material enough to create a slight degradation, resulting in a black mark. Foam occurs in the case of plastic marking when the ambient temperature is sufficiently raised to cause polymers to degrade the gases and create small bubbles. Ablation occurs when the material becomes extremely hot and the plastic deteriorates completely, leaving pure depression.
One particularly popular use of laser marking in recent years has been in bar coding and certification of diamonds. Using extremely tight rays at very low wavelengths in a deep ultraviolet range, the codes can be written in diamonds without virtually without external damage. The 193nMse Excimer Laser uses so small brand to make it completely invisible to the naked eye, and not intensive enough to make the chances of cracking or splitting near zero.
laser marking can be used on all kinds of substrates including wood, metal and glass inlured. In addition to barcodes and other tracking information, many companies use laser marking to add your logo to parts or products. Another advantage is that marking can be used in difficult to reach areas; Everything required is a direct view for the laser beam.
