Industrial Laser Marking Systems for Printing and Coding applications
Laser marking is a non-contact printing method that offers advantages over other technologies including mark quality, permanence and fewer consumables. Videojet’s line of laser marking systems includes CO2, Fiber and UV laser sources in different power outputs to address a range of substrates and applications. In addition, Videojet offers a comprehensive portfolio of laser accessories including lenses and beam turning units to simplify integration into your production lines and maximize the laser’s performance.
Designed to deliver crisp, high-quality codes, the Videojet CO2 laser range offers the most flexible configuration options for line integration.
Designed for simple coding applications with the maximum line speed of 60 m/min (197 ft/min)
The fiber laser marking range was developed to meet the needs of manufacturers who work with robust, high-density packaging materials on moderate or high-speed lines.
UV laser marking system The Videojet UV Laser delivers high-contrast, permanent codes enabling product lifetime track and trace on substrates like HDPE and LDPE plastic, and other synthetic fiber materials such as DuPont™ Tyvek®
Durable and clean complex codes:
Achieve permanent and precise codes without damaging the substrate or compromising on product aesthetics. Videojet lasers can produce high-contrast codes on a variety of product colors and substrates and are capable of coding precise, detailed information such as wiring diagrams, regulatory information, and logos.
Laser marking is marking with laser light without any additional inks, paints, mechanical tools such as needles. When the laser beam hits a product part of the laser light is absorbed. This energy transfer can cause a product surface change which is the code. Marking by laser is accomplished via color change and/ or surface structuring (melting, foaming, engraving resp. surface removal). The result: a permanent code into the surface of the product.
Using an RF signal, carbon dioxide (CO2) is stimulated electronically inside the laser tube, generating a laser beam.
When the laser beam is focused or steered onto the packaging material by a series of galvo mirrors through a lens, the beam is absorbed, and heat develops. Codes marked with the steered laser beam are solidly filled.
Depending on the packaging type, laser technology converts the heat generated from the beam into a mark on the product:
- Color change from chemical reaction
- Engraving from melting, burning or cracking the top surface layer
- Ablation or removal of the surface coating or decorative paint of a package creates contrasting colors
- Continuously imaged material produces characters, logos, and bar codes with continuous lines. This greatly improves the mark’s legibility
- Permanently mark on a wide variety of materials. This permanence helps prevent tampering of your marked information (to help reflect and support your brand’s image) and it is important in traceability applications.
- Mark in any orientation, even bottom up, for simple production line integration.
- Mark a wide variety of different text styles to better match your packaging styling. This improves your brand image and improves the consumer’s sense of quality in your product.
- Filters are the only supplies required for efficient laser operation. The costs associated with purchasing and storing consumables, and the operating costs associated with keeping printers filled with consumables are eliminated.
- The lack of fluids and marking consumables can create an overall cleaner operation, which is advantageous in food production since it helps eliminate the likelihood of ink-related product contamination.
- Fewer environmental challenges – laser is more forgiving in your production environment because it isn’t impacted by the temperature and humidity changes common in any production environments.
- Greater uptime because of less ongoing maintenance and operator intervention.
