Application examples of laser marking and part marking in mechanical engineering
The marking of parts in mechanical engineering takes place for 3 reasons:
- Marking information regarding the technical function of the workpiece (product information)
- Marking indications regarding the product or manufacturer for the traceability (variable data as e.g. batch number, production date, etc.)
- Permanent laser marking (e.g. logo) as counterfeit protection
The range of materials used in these components, including stainless steel, anodised aluminium, coated metals and plastics, are all perfectly suitable for laser processing. When laser marking metals, a fiber laser can effectivley mark without the need for addtional marking solutions. A CO2 laser requires the use of additional pastes or sprays.
