What is Laser Marking, and How Does it Work?

What is Laser Marking, and How Does it Work?

Understanding the Basics of Laser Marking Technology

Laser marking is a non-contact printing method that uses high-intensity light beams to mark objects without damaging the surface. This process involves directing a laser beam onto a material, which absorbs the light and converts it to heat, causing a reaction that leaves a permanent mark. The method’s precision and permanency make it ideal for various applications, from engraving barcodes and logos to detailed graphic designs.

The Role of Laser Source in Marking and Engraving

The laser source is the heart of the laser marking machine, defining its capability to mark different materials and achieve various effects. The most common laser sources include:

  • Fiber Lasers: Fiber Lasers are best for marking metals and plastics due to their high intensity and precision.
  • CO2 Lasers: Ideal for marking non-metallic materials and organic materials like wood, glass, and leather.
  • UV Lasers excel at marking sensitive materials without generating heat and are suitable for plastics, glass, and some metals.

Each laser type has its own set of parameters, such as wavelength, power output, and pulse durations, which can be adjusted to achieve the desired marking depth, contrast, and speed.

Comparing Laser Marking, Engraving, and Etching

While often used interchangeably, laser marking, engraving, and etching are distinct processes:

  • Laser Marking Alters the material’s surface color or appearance without removing the material. It is suitable for high-contrast marking for readability and traceability.
  • Laser Engraving: Removes a portion of the material to create a cavity that reveals an image or text at eye level. This method is deeper than etching and is ideal for applications requiring durability.
  • Laser Etching: A subset of engraving, etching melts the material’s surface to create a raised mark. Due to its speed and efficiency, it is often used for labels and barcodes.

By understanding these differences and the role of the laser source, businesses can better select the appropriate technology for their specific marking, engraving, or etching needs.
