Fiber Laser Marking Machines
High-contrast permanent marks on metals and engineering plastics, on the fly or at a workstation.
Also called fibre laser coders, MOPA laser markers and metal laser engravers.
What these machines do
Fiber lasers emit near-infrared light at around 1064 nm, a wavelength that metals and many dense plastics absorb efficiently. The result is a permanent mark — annealed, engraved or colour-changed — with no ink, ribbon or label to buy.
A ytterbium-doped fiber source generates the beam, a pair of galvanometer mirrors steers it across the marking field, and an F-theta lens keeps the spot in focus over the whole area. On moving lines an encoder tracks product speed so the code stays undistorted. MOPA sources add adjustable pulse width, which is what makes black marking on anodised aluminium and colour marking on stainless steel possible.
Typical options
- Rotary axis for cylindrical parts
- Class 1 safety enclosure with interlocked door
- Inline code reader with reject output
- Beam-turning unit for side or bottom marking

Process sequence
Detect
A photo-eye or PLC signal tells the controller a part has arrived.
Track
The encoder reports line speed so the scan head can follow the moving surface.
Mark
Galvo mirrors steer the pulsed beam to draw text, logos, 1D and 2D codes.
Extract
Fume extraction removes particulates at the marking point.
Verify
An optional camera reads the code back and rejects any failure.
