Laser Marking & Laser Engraving Systems

Our laser marking systems can be integrated into your existing production line or used as a stand-alone system, making it easy to mark logos, 2D codes, QR codes, serial or batch numbers on a variety of materials, including metals, plastics, ceramics and more.

Vanadate Laser Marking

The term vanadate laser is usually used for lasers based on neodymium-doped vanadate crystals. These lasers run on a wavelength of 1064nm, which is the same as nd:YAG. Despite this similarity, vanadate lasers are renowned for providing better quality marks due to their small, accurate spot size. With an average diode life of greater than 25,000 working hours, and low replacement cost, these lasers offer the user best-in-class reliability, with low cost of ownership.

We offer the world’s smallest vanadate laser, as well as a portable solution which allows large parts to be marked without moving them.

The key features of our vanadate laser marking solutions include:

  • Marks a wide range of materials including metals and plastics
  • High-quality beam diameter and movement
  • Higher peak power allows for marking onto uneven surfaces
  • Air cooled
  • No consumables are required
  • Can be mounted in any orientation
  • Easy to integrate
  • Available in a variety of wattages

Fiber Laser Marking

A fiber laser is a laser in which the active gain medium is an optical fiber, doped with rare-earth elements. In layman’s terms, it is a type of solid-state laser, where the laser light passes through the fiber, amplifying it to create a high-quality beam, which enables marking. Running on 1060-1080nm, this reliable technology is designed to withstand the vigour’s of a production environment and is best suited to continuous production environments.

Our fiber laser marking machines are perfectly suited to work in a heavy duty environment where deep or fast engravings are required, thanks to their robust designs. This durability makes them perfect for integration into a high-volume production line, and a dual-scanning head version can further boost production throughput.

The key features of fiber laser systems include:

  • Marks a wide range of materials including metals and plastics
  • No consumables are required
  • Minimal maintenance
  • Smallest footprint of any laser technology
  • Air cooled
  • Can be mounted in any orientation

Green Wavelength Laser Marking

Green wavelength lasers are fiber-coupled, diode-pumped, solid-state green wavelength lasers, which create high beam quality and laser stability. They offer extra power and speed for precision marking, and are the ideal choice for laser marking, scribing, trimming and other material processing applications. A green wavelength laser system has an average diode life of more than 100,000 working hours and offers best-in-class reliability. The robust mechanical and optical design enables operation in an industrial environment, where shock, vibration and dust are a concern.

The key features of green wavelength laser machines include:

  • Longest focal tolerance
  • High quality and high speed marking
  • Able to mark materials that other lasers can’t
  • Marks a wide range of materials including some metals and plastics
  • No consumables are required
  • Minimal maintenance is required
  • Air cooled

Nd: Yag Laser Marking

Nd:YAG is the acronym for yttrium aluminum garnet (YAG) and is a synthetic crystal material which became popular in the form of laser crystals in the 1960s. With a frequency of 1064nm, like vanadate laser systems, they produce high quality, high-speed marking on a variety of substrates. The Nd:YAG laser is a good alternative to traditional marking systems because of its flexibility and minimal maintenance requirements.

The key features of the Nd:YAG laser include:

  • Marks metals, plastics, foils and ceramics
  • Easy to integrate into production lines
  • Highly flexible
  • Minimal maintenance required
  • Thermo-electrical air-cooling system comes standard

Galvo CO2 Laser Marking

The CO2 laser, otherwise known as a carbon dioxide laser, was one of the earliest gas lasers developed and is, to-date, one of the more commonly used. These lasers are the highest-power, continuous-wave lasers that are currently available, running on a wavelength of 10600nm. These laser marking systems are excellent for marking organic substrates like wood, glass, ceramics, fabrics, etc. Mark-On-The-Fly versions are available for applications dependent on line speeds up to 2700 ft/min (900 meters per minute), as well as embedded controller versions requiring no separate computer.

The key features of the CO2 laser include:

  • Available in various wattages
  • Lowest initial cost compared to other types of lasers
  • Air cooled
  • Marks various substrates - including plastics, woods, leather, glass and even metals (with the assistance of an additive)
  • High quality and high speed marking
  • No consumables are required
  • Minimal maintenance is required

Laser Additives

Supplied as a masterbatch granulate, the laser additive can be added to a wide range of polymers to yield photo-quality, dark laser marks on light backgrounds. Unlike the current method of using a laser beam to carbonize the plastic itself, the additive contains well-defined laser-active particles which change colour under laser exposure so that consistent marking is obtained irrespective of the polymer.

Laser marking with additive offers numerous advantages, including improved productivity and total system cost reduction due to the simplicity, flexibility, and robustness of the new process. Small series customisation can easily be realized without any additional costs. Other features that are supported by laser additive technology are anti-counterfeiting and tracking & tracing markings.

Due to the high definition that can be obtained with the micro markings, 2D-data matrix or barcodes can be used to uniquely code a product. Such marks can be located - for example - in complex closure recesses found in dispensing closures, which are very difficult to reach with conventional printing technology.
