What is CO2 Laser Engraving?

Published in Laser Technology 2 mins read

CO2 laser engraving is a process that uses a high-powered carbon dioxide (CO2) laser to etch or mark materials. This method is especially effective for high-speed, high-volume applications, particularly on non-metal materials.

Understanding the Process

CO2 laser engraving works by directing a focused beam of light generated by a CO2 laser onto the surface of a material. The laser beam's energy vaporizes, ablates, or changes the material's surface, creating a permanent mark or engraving.

Key Features & Applications

  • High Speed: CO2 lasers can operate at very high speeds, capable of marking up to 2,100 characters per second in some applications.
  • Versatility: While commonly used on materials like wood, acrylic, leather, paper, and textiles, high-performance CO2 lasers are also used on certain glass and plastic packaging.
  • Precision: The focused laser beam allows for intricate designs and fine details to be engraved with high accuracy.
  • Common Applications: CO2 laser engraving is widely used across industries, including:
    • Packaging: Marking glass and plastic containers in the pharmaceutical, tobacco, and beverage industries.
    • Signage: Creating custom signs and displays.
    • Personalization: Engraving gifts, awards, and promotional items.
    • Manufacturing: Marking parts and components for identification and traceability.
    • Textile Industry: Cutting and engraving fabrics and leather for apparel, accessories and home decor.

Advantages of CO2 Laser Engraving

  • Non-Contact Process: The laser doesn't physically touch the material, reducing the risk of damage or distortion.
  • Permanent Marking: The engravings are durable and resistant to wear and tear.
  • Computer Controlled: Digital designs can be easily transferred to the laser engraver for precise reproduction.
  • Cost-Effective: For high-volume production, the speed and efficiency of CO2 laser engraving can result in lower per-unit costs.

In summary, CO2 laser engraving is a versatile and efficient method for marking and etching a wide range of materials, particularly well-suited for applications requiring high speed and precision, making it an ideal choice for industries requiring high-volume marking, such as pharmaceutical packaging.
