Industriell lasermärkning

Fiber Lasers

Fiber lasers are the default choice for industrial laser marking. They mark metals faster than any other laser type, run 24/7 in high heat, dust, and oil, and need essentially no maintenance (no optical realignment, no consumables, no print heads).

With enough power, the same laser that etches a data matrix code can also engrave deep enough to survive shotblasting, or strip paint, oxide, and rust from the surface before marking.

UV Lasers

UV lasers trade speed for precision. At 355 nm, they mark through a cold process that leaves no heat damage, which makes them the option for delicate and heat-sensitive parts (PCBs, silicon wafers, glass, ceramics, coated surfaces, and fine wires).

Spot sizes go down to 7 µm, small enough for markings that other lasers can't resolve, and they can mark on the fly. Where fiber lasers are too aggressive, UV is usually the answer.

CO2 Lasers

CO2 lasers are typically used to mark carbon-based materials (plastics, wood, cardboard, fabrics, and rubber). They work well on thin, flat parts. Their tradeoff is automation: their optical configuration makes them sensitive to the mechanical vibration found on production lines, and misalignment means downtime. For inline applications, you should test whether a fiber or UV laser can mark your material first.

Marking That Survives Shotblasting, E-Coating & Heat Treatment

Traceability only works if the code is still readable at the end of the line. Shotblasting normally erases direct part markings. With the right cell size/depth marking ratio, blast particles can’t damage the code readability.

Laserax sizes the data matrix to match your specific blasting media using a custom process. That means die cast parts can hold traceability from die extraction all the way to the assembly line.

Markings also need to remain legible through e-coating, powder coating, and heat treating. We can help you integrate a process that will resist post-treatment processes.

Laser Safety: Class 1 vs. Class 4 in Production

With a Class 1 turnkey machine, operators need no protective eyewear, no restricted laser area, and no separate safety program. The machine arrives compliant and drops into an existing line.

Integrating an open-beam Class 4 laser marker means the responsibility shifts to you: appointing a laser safety officer, training personnel, installing barriers, curtains, interlocks and signage, and supplying eyewear rated for the specific wavelength. That work is worth doing when the laser has to be embedded in a larger automated cell.

How Much Does an Industrial Laser Marking System Cost?

An industrial laser marking system starts at around $35,000 to $40,000 for a standalone laser marker (a laser source, scanner, and controller you integrate into your own line or enclosure).

A complete turnkey machine costs more because it includes the Class-1 enclosure, dust and fume extraction, part handling, safety certification, and software. Manually loaded workstations start at roughly $120,000, and higher-throughput configurations like a rotary table start closer to $230,000. Fully automated robot and conveyor cells are quoted per application.

Most of the variation comes from four things: laser power, automation level, safety and certification requirements, and options like autofocus, vision systems, and barcode validation.

Higher power costs more but buys back cycle time, which is usually the deciding factor on an inline application.
