Laser Engraving and Marking

Laser Technology Janssen provides high-precision laser engraving and marking for permanent identification, traceability and functional labelling of industrial components. Using advanced laser technology, the company creates sharp, wear-resistant markings with micron-level accuracy.

Laser engraving removes material to create a deeper, tactile marking. This is particularly suitable for components exposed to intensive use or demanding operating conditions. Laser marking alters the surface through controlled discolouration or oxidation, producing a permanent marking while preserving the component’s surface.

Both processes are contact-free, fast and highly reproducible. They can be applied to stainless steel, aluminium, titanium, plastics, ceramics and various other materials. Careful heat control minimises distortion and prevents unwanted discolouration around the marking.

Typical applications include:

• Serial and batch numbers
• QR codes and Data Matrix codes
• UDI and CE markings on medical devices
• Logos and product identification
• Scales and technical markings
• Traceability codes for precision components

Automation is available for series production and applications requiring reliable component traceability. Laser Technology Janssen can also advise customers on marking position, readability, material selection and process optimisation. Production ranges from individual prototypes to larger series and can be carried out in a cleanroom environment when required.
