Your experts for laser marking

Laser marking allows for extremely fine, microscopic markings—ideal for tiny lettering, complex geometries, DataMatrix codes, or intricate logos. Even on sensitive or hard-to-reach surfaces, the marking remains clear and precise.

Markings are permanent, wear-resistant, and withstand chemicals, moisture, and other environmental influences. This means they remain readable even after many years, ensuring reliable traceability.

Whether serial numbers, QR codes, logos, or individual customer requirements: laser marking can be adapted quickly and flexibly—even when requirements change or new ones arise. Using lasers, we can mark almost any material: metals, plastics, glass, ceramics, wood, and more. Curved, textured, or sensitive workpieces can also be processed easily and individually.

The permanent and precise marking protects against tampering and forgery. It allows for complete traceability—a decisive advantage in security-related industries.

Since there is no direct contact between the tool and the workpiece during laser marking, there is no mechanical stress or wear on the material surface. The process is non-contact and therefore particularly gentle on the object being marked. This prevents damage, deformation, or scratches to the material. Laser marking is an extremely precise, clean, and durable process. It guarantees flawless results even on sensitive or high-quality surfaces.

FAQ: Frequently asked questions

Laser marking

works by directing a highly focused laser beam onto the surface of a material, causing a permanent alteration. The laser beam is generated by a laser medium, directed via mirrors and lenses, and focused onto a very small point, creating a high energy density.

Depending on the material and the desired result, there are various methods:

Material removal:A laser beam removes material from the surface by locally heating and vaporizing it. This creates engravings or deep markings that are highly durable and resistant.
Color change: Laser energy causes a chemical reaction in some materials, such as plastics or organic materials like wood, which leads to a color change. This creates high-contrast markings without removing any material.
Paint ablation: For coated materials, the laser can selectively remove the top layer, exposing the material underneath.
Annealing: Through targeted heating, the laser can create an oxide layer on metals that leaves colored markings without removing any material.

The actual marking is created by the interaction of the laser beam with the material surface. The material must absorb the laser radiation well to achieve the desired change. The laser beam is usually controlled by a computer, allowing even complex patterns, lettering, or codes to be applied quickly to materials.

Depending on the material and application, there are various types of lasers to choose from (e.g., fiber lasers, CO₂ lasers, UV lasers). Laser marking is contactless, highly precise, customizable, and requires no materials.

The process is versatile, durable, and gentle on materials.

Different types of laser marking, their differences, and fields of application

Laser marking is a general term for various processes used to permanently, precisely, and non-contact mark materials. The most important types of laser marking differ in their operating principles, their effects on the material, and their optimal areas of application.

Important types of laser marking

1. Temper marking (tempering)

Process: The laser precisely heats the metal surface, causing oxidation to form a thin, colored layer. No material is removed.
Properties: Markings are colored (e.g., black, blue, yellow), non-tactile, and highly corrosion-resistant.
Application: Particularly well suited for stainless steel and other ferrous metals, e.g. in medical technology, surgical instruments, or machine parts

2. Laser engraving

Process: The laser beam vaporizes or melts the material, removing it and creating a noticeable recess.
Properties: Highly durable, abrasion-resistant, and clearly visible marking to withstand wear and tear.
Application: All-purpose use for metals, plastics, wood, glass, etc.; often used for tools, machine parts, jewelry, nameplates

3. Ablation (Laser ablation, Paint removal)

Process: The laser precisely removes coatings, paints, or oxide layers without significantly affecting the base material.
Properties: Enables high-contrast markings, e.g. by exposing underlying layers of paint.
Application: Used in automotive engineering (illuminated switches, control elements), the packing industry, and electronics.

4. Foaming

Process: The laser locally melts the plastic surface, creating trapped gas bubbles which brighten the marking.
Properties: High-contrast, bright marking on dark plastics, tactile raised surface.
Application: Primarily for plastic parts, e.g., housings, cables, switches.

5. Carbonize (Color change)

Process: The laser causes a local chemical reaction, usually carbonization, resulting in dark markings.
Properties: Ideal for light-colored plastics, since the marking turns black.
Application: Electronics, household appliances, cable labeling.

6. Sub-anodic marking

Process: The laser precisely removes the color layer from anodized aluminum without damaging the metal.
Properties: Long-lasting, high-contrast marking.
Application: Nameplates, front panels, device labeling.

7. Laser polishing

Process: The laser polishes the surface locally, resulting in a shiny impression.
Properties: Decorative, no material removal.
Application: Jewelry, design pieces, logos

Common laser types and their applications

Fiber laser: Versatile, suitable for metals and some plastics. Used in the automotive, medical, and electronics industries.
CO₂-Laser: Ideal for organic material such as wood, glass, paper, and plastics. Frequently used in the packing industry.
Green- und UV-Laser: For sensitive materials like precious metals, foils, circuit boards, glass, and plastics free of additives.
Vanadium-Laser: Used for high-consistency applications and heat-sensitive materials.

Material characteristics and suitability

Stainless steel is denser, tougher, and more resistant than aluminum. It is particularly suitable for applications with high requirements for durability, corrosion resistance, and mechanical stress.
Aluminum is significantly lighter and malleable, making it ideal for large-scale or weight-optimized applications. It is easier to shape and is well-suited for intricate designs or large signs.

Labeling process and quality

For stainless steel, the preferred method for permanent and corrosion-resistant marking is laser annealing. This involves targeted heating of the surface without removing any material, ensuring the protective chromium oxide layer remains intact and preventing corrosion. The result is high-contrast, usually black markings that are particularly durable.
Laser engraving on stainless steel removes material and thus the chromium oxide layer, which may impair corrosion resistance and lead to rust. Therefore, annealing is generally recommended for stainless steel instead of engraving.
Aluminum can be easily engraved or marked, as the natural oxide layer quickly reforms after engraving to protect the material from corrosion. Engravings on aluminum are high-contrast and durable, especially on anodized surfaces.

Surface finish and optics

Stainless steel offers a shiny, reflective surface and retains its shape even under heavy use. Various finish options, such as satin, polished, or orbital, are available.
Aluminum typically has a dull or brushed finish but can be enhanced through anodizing or powder coating. It is more susceptible to scratches and deformation, yet is easier to work with.

Attribute	Edelstahl	Aluminium
Weight	Heavy	Light
Hardness/Tensile strength	Very high	Medium, rather soft
Corrosion protection	Chromium oxide coating, highly durable	Oxide layer, durable
Labeling process	Laser annealing is preferred, Engraving possible (with restrictions)	Engraving and marking are possible
Optics	Glossy, polished, brushed	Dull, brushed, anodized
Machinability	Challenging	Excellent, delicate designs

Selecting the appropriate material and process depends on the demands for durability, weight, appearance, and cost.

Laser marking has several benefits when compared with traditional methods:

Durability and resilience: Laser markings are extremely resistant to abrasion, chemicals, moisture, and other environmental influences. Unlike labels, which can peel off, fade, or become damaged, laser markings remain permanently intact even during demanding production processes such as reflow soldering, cleaning, or contact with chemicals.
No disposables: Laser marking eliminates ongoing costs for labels, ribbons, or ink. This cuts operating costs and reduces logistical effort, as there is no need to stockpile materials or refill supplies.
Precision and versatility: Lasers can be used to apply even the smallest, most complex, and detailed markings—even onto very small or irregular surfaces. Often, labels are not suitable for this purpose.
Variety: Laser marking works on a wide variety of materials such as metal, plastic, glass, wood, and even consumables. It is not limited to specific surfaces or shapes.
Counterfeit-proof: The marking is applied directly and permanently to the product, making it difficult to tamper with or remove—an important aspect for product protection and traceability.
Automation and efficiency: The laser process can be easily incorporated into existing production lines and enables fast, contactless, and automated marking—ideal for high volumes.

By comparison, labels are susceptible to peeling, damage, and environmental exposure, and generate ongoing costs for materials and maintenance. This makes laser marking the more economical, robust, and sustainable solution for many industrial applications.

Laser marking speed is a decisive advantage for industry because it directly contributes to increased productivity. Laser marking systems operate at very high cycle rates and can apply markings in fractions of a second, enabling fast and efficient processing of large quantities.

This significantly speeds up production processes without compromising the precision or quality. Furthermore, the high working speed minimizes downtime and enables smooth integration into automated production lines, which is particularly important in the age of Industry 4.0.

Another advantage: The speed of laser marking remains consistent, even when making individual adjustments or changing product batches. Frequent product or serial number changes do not require changeover times, as adjustments can be made digitally.

In summary, the high speed of laser marking allows for:

a significant increase in production capacity,
a reduction in turnaround times,
flexible and efficient implementation of customizations,
and economical production even for large quantities.

These factors make laser marking an ideal technology for industrial production and significantly increase companies' competitiveness.
