What is laser marking?


While laser engraving and laser marking techniques are similar, they are slightly different and serve unique purposes. Laser engraving uses a laser beam to physically remove the surface of a material and create a permanent mark that can withstand harsh environmental and operating conditions. This process is slower than laser marking, but gives more reliable results.

Laser marking is the process of passing a laser beam through a lens and focusing it on the surface of a part. When the beam interacts with the surface of the material, it slightly changes its appearance or properties. Unlike laser engraving, marking permanently modifies products without removing materials. Wattsan supplies top-notch industrial laser marking machines with quality, durability and performance.

Application of laser marking machines

Such devices are used to mark products, such as the date and time the product was manufactured in serial or mass production. Laser markers also create one and two-dimensional barcodes. The following equipment is used:

  • in industry;
  • in advertising and souvenir sphere;
  • in mechanical engineering;
  • in the manufacture of medical products;
  • in the food industry and so on.

These machines are in demand everywhere: from perfume production to shipbuilding. With their help, microcircuits, watches, cutlery, cables, packaging, plastic cards and so on. Without laser equipment, it is difficult to imagine the production of plates or company logos. Laser equipment is especially popular today in the manufacture of souvenirs and promotional products. With the help of a laser, you can create any high-quality image on souvenirs, gadgets, monuments, and so on.

The drawing is burned on the surface of the material, while the material itself is not destroyed and does not lose its properties. Such processing does not produce waste. Laser equipment can work with both metal and organic materials. For example, a CO2 gas laser can work with wood, glass, leather, rubber, plastic, paper, acrylic and carbon. And for the processing of metal and ceramic materials, it is necessary to use a fiber optic laser.
