Laser Marking
Laser marking permanently marks text, logos, serial numbers, barcodes and QR codes onto metal and plastic parts using a focused laser beam. The marks resist wear, heat and chemicals, making them ideal for traceability and branding.
What it is
Fiber lasers mark metals by annealing (colour change without material removal), engraving (removing material) or ablating coatings. Plastics are marked by colour change or foaming. The process is non-contact and fast.
Variable data such as serial numbers and date codes can be changed automatically part to part.
Typical applications
- Part numbers and serial numbers
- Barcodes and QR/DataMatrix codes
- Logos and branding
- Tool and gauge marking
- Nameplates and labels
Suitable materials
- Stainless steel and steel
- Aluminium (bare and anodised)
- Brass and copper
- Engineering plastics
- Coated and painted parts
Points to consider
- Annealing marks on stainless keep the surface smooth, suitable for medical and food parts.
- Anodised aluminium marks with high contrast.
- Provide artwork as vector files (DXF, AI, PDF).
- Mark position and size should be shown on the drawing.
Frequently asked questions
Is laser marking permanent?
Yes. Laser marks resist wear, heat and chemicals and don't fade like printing.
Can laser marking do serial numbers and QR codes?
Yes. Variable data like serial numbers, barcodes and QR/DataMatrix codes are marked automatically.
What is the difference between laser marking and engraving?
Marking changes the surface colour with little or no depth; engraving removes material to create a recessed mark.
