Best Kind of Fiber Laser Marking Machine for Marking on Metal

When selecting the best fiber laser marking machine for metal, key factors include laser power, wavelength, marking speed, precision, and material compatibility. Here is a breakdown of the top options:

**1. MOPA Fiber Laser Marking Machine

• Best for: Stainless steel, aluminum, titanium, brass, coated metals

• Power Range: 20W – 100W (30W–50W is most common for detailed marking)

• Wavelength: 1064 nm (ideal for metals)

• Key Features:

• Adjustable pulse duration (fine-tune marking depth/contrast)

• High-speed marking (up to 7000 mm/s)

• Can create color marks on stainless steel (without paint)

• Excellent for deep engraving, annealing marks, and high-contrast black/white marks

✅ Best Choice for aerospace, medical devices, and electronics where precision & aesthetics matter.

**2. Q-Switched Fiber Laser Marking Machine

• Best for: High-speed industrial marking (serial numbers, barcodes, logos)

• Power Range: 20W – 50W

• Key Features:

• Fixed pulse duration (faster but less flexible than MOPA)

• Reliable for deep engraving & permanent marks

• Lower cost than MOPA but less color marking capability

✅ Best for automotive parts, tools, and industrial metal tags.

**3. High-Power Fiber Laser (50W–100W+)

• Best for: Deep engraving on hardened steel, cast iron, heavy-duty metals

• Applications:

• Military equipment

• Industrial machinery parts

• Thick metal engraving (1mm+ depth)

✅ Best for heavy-duty applications requiring deep marks.
