Extrusion Laser Marking

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?

Automative Compliance

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.

Serialize Extrusions

Automatically Identify Scrap

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

Adaptable 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.

Reduce Operation 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.

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.

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.).

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!

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.

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 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.
