Aluminium Extrusion

Aluminum Extrusion Laser Marking 

Aluminum extruders are facing new challenges as more and more programs demand that parts be marked as soon as they're off the press.

Since inkjet printers are not permanent and hence not suited for automotive programs, an increasing number of extruders are turning to laser marking to permanently etch data matrix codes and serial numbers.


Why Extruders Choose Laserax?

Meet Automotive Standards

Meet New Automotive Standards

Laser marking provides reliable inline traceability without limiting the throughput of your extrusion press, allowing you to apply to automotive programs such as IATF 16949 and ISO 9001.

Identify Scrap

Automatically Identify Scrap

Our laser technology can serialize extrusions and identify scrap on the fly at the exit of the press.

Easily Adapt to Various Shapes

Easily Adapt to Various Shapes

With our autofocusing technology, you can create high-contrast human readable characters and barcodes no matter the profile shape.

Lower Operating Costs

Lower Operating Costs

Reduce your operating costs to almost zero. While inkjet printing runs on expensive consumables and requires regular maintenance, laser technology runs on electrical power alone, is energy efficient, and requires little to no maintenance.

Granco Clark Partners with Laserax to Integrate Laser Etching

The LXQ laser produced by Laserax has allowed us to meet our customers’ requirements in the extrusion industry. We have been able to meet OEM requirements for traceability, increase product quality and most importantly, reduce downtime—an important problem with other technologies.

What Are the Challenges for the Extrusion Line?

Laser markers are already widely used to identify finished extruded parts. But marking extrusions directly on the press is more challenging. Here are the most important challenges that must be overcome for a successful integration.

  • Conveyor production speed

    Match Production Speed

    On the extrusion line, new profiles constantly need to be marked while in movement. Our lasers are ideal to mark extrusions moving at a high speed—up to 230 ft/min. (70 m/min.).

      Typical Laser Power Required

      Extrusion speed Alphanumeric characters 10 x 10 data matrix code
      10 m/min. - 30 ft/min. 20W 20W
      30 m/min. - 100 ft/min. 30W 50W
      50 m/min. - 165 ft/min. 50W 100W
      70 m/min. - 230 ft/min. 100W
  • adaptable laser marking process

    Adjust the Marking Process to Varying Geometries

    If your manufacturing process includes varying profile geometries, the laser marker needs to adjust accordingly to stay in focus. Our 3D head achieves that with its long marking range of 150 mm and its dynamic autofocus capabilities. No need for complex mechanical setups!

  • Multiple extrusions

    Mark Multiple Extrusions at Once

    If you are extruding multiple profiles at the same time, you will encounter problems if the laser’s field of view is too small. Our LXQ fiber lasers have a 300 x 300 mm marking window so they can mark multiple profiles at once.

  • safety environments

    Mark in Harsh Environments

    The high temperature of the extrusion line and water quenching create a rough environment for laser marking systems. Our LXQ fiber lasers bear an IP67 protection rating so they can be positioned anywhere, even face up below the extrusion.

  • Ensure workplace safety

    Ensure Worker Safety 

    To ensure safety, our laser marking machines come with a certification that your installation is 100% safe according to international Class-1 laser safety standards, guaranteeing that laser beams are properly enclosed.
