Laser Marking on Glass
Laser marking produces permanent high-resolution codes on nearly any color or type of glass. The permanent marks protect codes from being tampered with by unauthorized channels. Moreover, high-quality marking enables clear coding and help instill brand confidence with customers.
Why choose lasers for marking on glass?
Laser marking offers five advantages in comparison to ink-based printing systems.
- Permanent and durable marking that withstands harsh environments.
- High precision and clarity to help ensure legibility and quality.
- Non-contact process, reducing the risk of damage to the glass surface.
- Versatility in marking various shapes and sizes of glass surfaces.
- Cleanliness of the production environment.
Applications
Videojet laser marking solutions are ideal for:
- Beverage bottles: Produce clear and permanent date codes, batch numbers, and logos.
- Pharmaceutical containers: Enhance traceability with precise and durable markings.
- Cosmetic bottles: Achieve high-quality branding and product information.
Lasers offer clean operation without inks and other fluids. In addition, whether you are using CO2, fiber, or UV technology, a complete laser marking system requires fume extraction. These systems remove fumes, smoke, and particulate debris generated during the marking process, helping to keep the production environment clean.
Without requiring ink or ribbons, lasers enable operational cost savings over industrial printers.
Types of laser marking machines for glass
Creating permanent and high-contrast marks, CO2 is the most suitable laser technology to mark on glass.
CO2 lasers on glass
CO2 lasers deliver high-contrast codes on with variety of substrates including glass. These systems use a carbon dioxide gas mixture as the laser medium to create high-contrast marks. As a result, this innovative system is ideal for marking glass bottles and flat glass surfaces.
This information is only a glimpse of what a CO2 laser can do. We would always recommend speaking to a product expert to learn more about the different user interfaces, beam outputs, and any limitations that can exist to ensure you are choosing the right solution for your production needs.
