Laser Engraving

Laser Engraving Image

Laser engraving is the procedure of eliminating material from a surface using laser beam. It can be either through ablation or vaporization. The laser engraving machine it is attached to the computer. The images are designed on a computer then it is engraved with a CO2 laser beam. After that, it cuts your design on a wide variety of materials. The surface is melted and vaporized with the laser. The laser beam removes the material and a result of this, an engraved impression is created.

Process of Laser Engraving

The laser engraving process includes light intensification by stimulated emission of radiation. The light is amplified with the mirrors and then directed towards the product to be engraved. With the help of laser, the area is vaporized this removes the material from its path.  The laser does not transmit the color but it changes the color of the engraved product.
Moreover, the process of amplifying the light with mirrors is simple. The laser beam is created by the opening in one of the mirrors. This allows the energized light escape to the engraved the item. The diameter of the laser is determined by the size of the opening in the mirror. Laser can be directed accurately on smaller areas and the process can be repeated many times. 
The laser engraving equipment are selected according to the product being engraved. In the same way, it is important to choose the engraving software according to the product. The laser engraving technique uses intense heat and burning that results in discoloring of some materials. Materials that can change their color from the laser engraving includes plastic, aluminum, and copper. Aluminum usually turns white because of laser engraving. On the other hand, metal objects does not change colors but laser engraving can cut through the paint of the metal. Some metals change color and result in red, blue green or brown color. The copper product will change the color to brownish or gold.
There are 3 types of laser engraving:

  • Deep laser engraving
  • Etching
  • Laser ablation

Metal in engraved with Nd: YAG laser while other materials like rubber, wood, and plastic are engraved using CO2 laser.

Benefits of Laser Engraving

There are many advantages of laser engraving. Some of them are:

  • Laser engraving is a safe process, there is no fixation of product required during the process. The laser machine is sealed inclosure that provides maximum safety for the user.
  • This process provides very clean cutting edges and fine details.
  • Laser engraving machine works at full speed that increases the productivity. This make sit perfect for bulk orders.
  • The machines are easy to use as they feature an intuitive user interface.

Laser engraving is precise and can be used on many surfaces. Materials that are best for engraving includes:

  • Plastic
  • Glass
  • Wood
  • Metal
  • Aluminum
  • Ceramic
  • Acrylic
  • Leather.
