Did you know that laser marking plays a very critical role in the manufacturing process? The term Laser or Light Amplification by the Stimulated Emission of Radiation involves the release of particles of light after stimulating an atom. This method can be used to mark products with serial numbers, part numbers, text, machine-readable data, or graphics.

Advantages of Laser Marking


Various industries that include food, aerospace, automotive, medical, advertising, electronics, and semiconductor manufacturing use lasers for product labeling. Furthermore, lasers are automated and processed at high speeds to leave lasting traceability marks on a wide range of materials that include the following:

  • Silicon
  • Germanium
  • Steel
  • Aluminum
  • Titanium
  • Copper
  • Ceramic
  • Glass
  • Plastic
  • Wood
  • Paper
  • Cardboard


Since the concentrated beams of light only hit a specified area, it creates high-quality, high-contrast, and precise marks that are easy to scan or read. This makes it ideal for marking very small objects such as wafers and circuit boards with impressive accuracy.

Non-Contact Process

During the marking process, the equipment doesn’t come into physical contact with the surface of the material being marked. Since the laser beam only affects the areas it targets, this eliminates the risk of causing damage to the material by abrasion.


The use of lasers for marking products won’t have a significant impact on the day-to-day operation cost. Aside from the fact that the cost of electricity for the equipment is minimal, the system only requires little manpower for handling it. Once the machinery is set up, it automatically gets the job done at high speed.


Unlike other marking methods, the use of lasers doesn’t produce toxic fumes and waste products. No chemicals or inks are used during the process. This makes it safe for the environment and the person who’s carrying out the process.


Besides being water-resistant and fade-proof, the markings produced with lasers are can also withstand heat, acids, and abrasion. This makes it suitable for creating permanent markings for product tracing.
