Laser marking and laser labeling of metal

The laser marking and engraving of metal is one of the most precise and efficient methods of permanently marking surfaces. These technologies are indispensable in industry and numerous other areas for reliably marking components, products or tools.

Laser marking and laser engraving are processes that use a laser beam to create permanent marks on the surface of metals. Both methods use the energy density of the laser beam to change the metal surface and thus leave texts, barcodes, logos, serial numbers or other information.

Typical processes for metal:

• Engraving: Deep markings by removing material, ideal for robust and tangible inscriptions.
• Annealing: Color changes through targeted heat application, without removing the surface – often used with stainless steel.
• Ablation: Removal of a thin surface layer, for example with anodized aluminum or coated metals.
• Foaming: creating contrast by creating microscopic bubbles in the surface of the material.

Laser marking

Laser marking involves heating the surface of the metal, which changes the color of the surface or creates an oxidation layer. This method is particularly suitable when a high-contrast mark that is easy to read is required. Typical applications include marking tools, medical devices and automotive parts.

Laser marking

Laser marking goes a step further by removing material from the surface of the metal. This results in deeper marks that are particularly resistant to abrasion and corrosion. This method is widely used in the aerospace, electronics and consumer goods industries.

Precision

One of the biggest advantages of these technologies is their extraordinary precision. The laser beam can reproduce the finest details with high accuracy, which is particularly advantageous for complicated designs and small font sizes.

Durability

Both laser markings and laser inscriptions are permanent and withstand extreme conditions such as high temperatures, chemicals and mechanical stress. This makes them ideal for applications where durability and reliability are of the essence.

Flexibility

Laser technology is highly flexible and can be used on a wide variety of metal types and alloys, including stainless steel, aluminum, brass, and titanium. Furthermore, different marking depths and styles can be realized to meet the specific requirements of each application.

Non-contact process

No tool wear and no mechanical stress on the material.

Environmentally friendly

No chemicals or consumables are used, making the process particularly sustainable.

Laser marking and engraving of metal is an essential part of modern manufacturing processes in many industries:

Tool and machine construction

In tool and machine construction, permanent and precise markings are essential to ensure the traceability and identification of components. Laser markings offer a reliable solution here.

Medical technology

In the medical technology industry, the labeling of instruments and devices is of the utmost importance. Laser inscriptions ensure that the markings remain legible even after numerous sterilization cycles.

Automotive industry

In the automotive industry, laser markings are used to label parts and ensure their traceability. This is particularly important for quality assurance and safety standards.

Electronic industry

The electronics industry uses laser marking to identify microchips, printed circuit boards and other electronic components. These markings must be small, precise and long-lasting.

Jewelry and luxury goods

Individual engravings on jewelry, watches or exclusive design objects.

Aerospace

Marking components with serial numbers and technical information.
