Labeling of sensitive components without mechanical stress

Contactless laser marking for maximum precision in sensitive areas

Sensitive components are part of everyday life in the defence industry - whether in sensor technology, electronics, aviation technology or highly specialized composite components. However, it is precisely these sensitive materials that place enormous demands on every type of marking: even the smallest mechanical impact can impair functionality or cause damage. Traditional engraving methods such as milling or needle embossing are not an option here.

Contactless laser marking offers a modern and material-friendly solution to this challenge. Sensitive parts can be marked with the highest precision, complete contactlessness and maximum repeat accuracy - traceable, permanent and without mechanical stress.

Why mechanical-free marking is so crucial

As soon as components are particularly thin-walled, heat-sensitive or made of complex material combinations, conventional marking processes are too risky. Physical contact with a tool or even the smallest vibrations during engraving can lead to microcracks, deformation or surface damage.

The laser marker, on the other hand, works without direct contact. The energy is applied precisely to the surface - either through color change, structural change or targeted material removal. The component structure remains completely intact. Even with the tightest tolerances and complex geometries, contactless machining ensures maximum process reliability.

Typical areas of application in defense and aerospace technology

In many areas of the defense industry, the permanent and reliable marking of components is mandatory - whether for identification, quality assurance or complete traceability. Particularly sensitive components can be found in the following applications, among others:

• Sensor technology & microelectronics: Filigree components such as circuit boards, conductor paths or optical sensors often have to be marked with serial numbers, batch information or codes - a task that requires maximum precision with minimal thermal or mechanical impact.
• Composite materials: Carbon fiber (CFRP) or aramid components are indispensable in modern armament technology. At the same time, they are extremely sensitive to heat and pressure - non-contact laser marking is the only reliable solution here.
• Coated metal housings: Aluminum housings with an anodized coating or special surface finishes must be permanently marked without damaging the protective coating or impairing the function.
• Packaging protection & calibration equipment: Foam materials, protective coverings or sensitive test equipment can also be marked with the laser without causing wear or deformation.
