Laser marking
Laser marking is a versatile process that can label, engrave or apply specific codes (such as Data Matrix codes) to components by laser. Among other things, this enables to reliably trace components along the entire supply chain. Furthermore, the process allows the removal of thin cover layers, laser cleaning, foaming and in-process reading verification with our high-performance Trumpf systems.
Laser marking – advantages with BLS
Marking components with lasers offers extensive advantages over conventional marking processes based on colour, chemical reaction or mechanical pressure. Laser marking is characterised by a high degree of flexibility in the area to be processed and a high quality of marking with the finest structures and long durability.
What is laser marking?
Laser marking – also known as laser labelling – is a technologically mature process for marking and subsequent identification (e.g. for traceability requirements) of components. The marking is applied to the surface using an intense, pulsed laser beam.
Interactions between the laser beam and the surface cause a change in the material in the form of discolouration, material erosion or structuring. The form in which the material changes depends on the wavelength, the power density and the pulse duration of the laser beam.
The BLS systems also allow 100% proofreading during the process with a special read check of the previously performed marking.
Laser marking can be carried out in the form of various processes. A distinction is made between tempering, engraving, colour change and foaming. Which process is ultimately suitable for the application depends on the material and the associated quality and usage requirements of the product.
Over 35 years of experience and the trust of
more than 500 customers speak for us.
With extensive laser experience, BLS supports customers as a contract manufacturer from parameter determination / basic development through prototype production to series production. High-performance machinery and different types of lasers and systems enable an optimized overall product. The quality management system and exchanges with leading research institutions ensure quality at the highest level on a permanent basis.

Laser marking expertise
Components can be individually labelled using laser marking. By changing the wavelength, power density and pulse duration of the laser beam, different materials can be marked using the respective processes. The information content of the marking can be encoded using a code or displayed conventionally as labelling. VisionLine image processing can be used to detect, check and precisely localise weld seams, codes or markings.
