Laser marking

Permanent laser engraving applies unique information directly onto the material surface – such as serial numbers, DataMatrix or QR codes, logos, or part numbers.

These marks ensure automatic data capture and complete traceability throughout a part’s life cycle.

The mark remains permanently readable, even when exposed to abrasion, solvents, or harsh environments.

Permanent laser marking also enables full integration of production data into ERP and MES systems through automated decoding of the marked information.

European and international regulations – CE marking, UDI for the medical sector, AS9100 for aerospace and space, as well as ISO 13485 for medical devices – require permanent marking that remains perfectly readable and traceable throughout the product’s entire service life.

These technical requirements call for an engraving depth that is tightly controlled, a defined contrast, and high repeatability.

The mark must remain perfectly readable even after heat treatment, galvanizing processes, or exposure to chemical agents.

Laser marking allows precise adjustment of every essential parameter – power, frequency, speed, and focus – to achieve optimal contrast on materials such as stainless steel, titanium, aluminum, or plastics, ensuring long-lasting compliance.

The inline integration of laser marking consolidates previously separate processes into a single operation coordinated with the production flow.

This reduces downtime and maximizes overall productivity.

In addition, the inherently repeatable precision of laser marking delivers consistent quality without the need for frequent adjustments.

This lightens the operators’ workload and lets them focus on higher-value tasks.

Installing an automated laser marking station, connected to ERP or MES systems, results in fewer reworks and improved real-time traceability.

This has a positive impact on OEE metrics as well as on compliance with industry standards.

Because laser marking requires no consumables (inks, ribbons, solvents), operating costs drop immediately.

Furthermore, the long service life of laser sources reduces replacement frequency and maintenance requirements.

With no chemical additives or solvents involved, laser marking eliminates all consumables (such as inks or ribbons) along with the associated waste.

Fiber laser technology offers a service life that often exceeds 50,000 operating hours, reducing component replacement and the generation of electronic waste.

It produces neither liquid waste nor significant emissions, which lowers waste treatment costs and simplifies compliance with environmental regulations.

On the production floor, laser marking integrates easily into automated manufacturing lines and stands out for its controlled energy consumption – typically just a few hundred watts, depending on the power used.

The laser source settings are tailored to the specific characteristics of each material: steel, stainless steel, aluminum, titanium, and composite materials retain their mechanical properties while ensuring long-lasting mark readability.

Process parameters – power, frequency, pulse duration, repetition rate, and scan speed – can be customized to minimize the heat-affected zone and preserve mechanical tolerances.

With precise laser settings, it is possible, for example, to achieve optimal contrast on anodized aluminum without damaging the surface layer, or to prevent yellowing on engineering plastics.

Laser marking stands out for its extreme precision and exceptional engraving quality. The fine laser beam makes it possible to produce sharp lettering, detailed logos, and even microtext that remains perfectly readable at sizes below one millimeter. Depending on the system configuration, marking resolution reaches an exceptional level – ideal for applications where readability and durability are critical.
