Gravotech Laser Engravers

Gravotech's fiber, MOPA, hybrid, green, and CO2 marking lasers are built to mark metal, plastic, and alloys with permanent, code-compliant 1D, 2D, and Data Matrix identification for traceability. Fiber and MOPA models are the workhorses for metal marking, handling stainless steel, aluminum, titanium, and most alloys, while CO2 systems cover plastics, glass, and organic materials that fiber wavelengths don't mark well. This marking is permanent and abrasion-resistant, which is why it's the standard choice for parts that need to carry serial numbers or lot codes through harsh manufacturing or field conditions. The right laser type ultimately depends on the substrate being marked.

Unlike inkjet or label-based marking, Gravotech laser marking systems run without ink, solvents, or other consumables, which lowers per-part marking cost over time. Inkjet systems require regular cartridge and solvent replacement plus routine printhead cleaning, and label systems consume physical stock that has to be reordered and stored — costs that scale directly with production volume. Eliminating consumables removes a recurring line item from the marking budget and reduces the maintenance downtime that comes with keeping ink systems clog-free. The laser source itself is essentially the only wear component, and Gravotech backs it with a multi-year warranty on most models.

Gravotech's integrable laser markers are built as ready-to-integrate units that connect directly to most PLC brands without requiring extra computers or connection hardware. This is a meaningful difference from marking systems that need a dedicated PC running proprietary software just to trigger a mark — an integrable unit accepts standard I/O and communication protocols so it slots into an existing production line's control logic. That plug-and-play compatibility cuts integration time significantly on new or retrofitted lines, since engineers don't have to build a custom communication bridge. It's a common choice for OEMs adding traceability marking to an automated assembly or packaging line.
