WIDE RANGE OF LASER MARKING MACHINES SUITABLE FOR INTEGRATION AND STANDALONE WORKSTATIONS

LASER MARKING

Wide range of

laser marking machines FIBER, HYBRID, GREEN, CO2, MOPA, UV

Galvanometric lasers are designed with a series of mirrors that reflect the laser beam at very high speed, allowing for permanent marking in just second fractions.

This technology enables rapid, precise and high quality engraving for marking a wide range of industrial components, such as automotive, aerospace, automotive, foundry, plastic, electronic, electrical components, fittings, piping, oil & gas, and energy devices.

There are several types of laser sources that must be chosen based on the material to be marked and the technical specifications of the project being implemented.

Class 1 lasers: safety first! All our laser markers—both benchtop and in-line—are specifically designed to meet the highest Class 1 safety requirements for safe laser engraving in any factory production environment.

Technology and innovation help reduce waste and therefore indirect costs related to production inefficiencies: Gravotech's technological excellence allows you to increase productivity and cut costs: working efficiently pays off.

GREEN LASER

The GREEN laser is specifically designed for complex markings: the green laser is known for its "cold marking" properties due to its excellent results, even on materials that are unresponsive to other laser sources.

In addition, the GREEN laser features incredibly small spot diameters, offering unsurpassed marking quality and precision.

COLD MARKING COLD GREEN LASER MARKING

Cold green laser marking is a permanent marking performed with minimal thermal stress: the concentration of the laser beam allows marking without generating heat on the parts, avoiding burning or deformation, and thus without altering the material.

ULTRA-HIGH DEFINITION MARKING

Gravotech has developed green line laser engravers that guarantee extremely high-resolution markings known as "micro markings." They offer extremely small spot sizes and exceptional resolution, with virtually zero thermal stress on the material. Small 2D data matrix, detailed logo, precise removal of thin coating layers: the GREEN line laser series is able to meet all your most complex application challenges.

MARK THE IMPOSSIBLE

Its versatility is almost unmatched. This range uses a wavelength of 532 nm to mark materials that would not normally react to other wavelengths: from rough to more transparent plastics, reflective metals (copper, silver, gold), ceramics, cardboard, and wood.

MOPA LASER

MOPA benchtop and industrial laser marking machines

The MOPA laser is a fiber laser marking technology that stands out for its adjustable pulse duration and frequency, this technical feature delivers an high-precision engraving with high contrast and reduced heat generation, making it ideal for sensitive materials or those requiring superior finishes.

Some advantages of the MOPA laser:

PULSE DURATION ADJUSTMENT

Greater control over the type of marking, useful for delicate materials and for achieving high-contrast markings.

COLOR MARKING ON METAL

The MOPA can deliver color marking on metals such as stainless steel and titanium, achieving unique aesthetic effects.

REDUCTION OF HEAT-DAMAGE TO THE MATERIAL SURFACE

The MOPA laser marker is calibrated to the appropriate frequency range, thus limiting the heat-affected zone, preventing discoloration and deformation.

FLEXIBILITY

Wide range of workable materials, including metals, engineering plastics, and coated materials.

Materials suitable for the MOPA laser Metals:

Stainless steel, carbon steel, anodized aluminum, brass, copper, titanium, gold, silver, platinum.
Plastics: ABS, PVC, PET, PE, PP, PA (nylon), PBT, and other engineering plastics, especially heat-sensitive ones.
Coated and treated materials: painted, plated, electro-anodized, and chemically treated surfaces.
Others: some ceramics, composite materials, electronic components, and printed circuit boards.

Main applications:

Personalization and branding of metal and plastic objects.
Marking of plastic, automotive, aerospace, medical, and packaging components.
Engraving of engineering plastics and heat-sensitive materials without damaging them.

The MOPA laser is a versatile and advanced technology, particularly suited to processes requiring high quality, material flexibility, and precise aesthetic finishes, including high-quality metals and delicate plastics.

LASER MARKING PERSONALISATION TYPES ON METAL

Each marking process has its own specific characteristics, as it is applied to a specific component and must increasingly meet specific needs.

Depending on the configuration used, Gravotech laser marking machines allow us to customize the marking to achieve the desired result on your components based on:

Marking specifications
Material surface finish
Available effective cycle time
Engraving depth
Purpose of marking

LASER MARKING ON FIREPROOF PLASTIC

Thanks to significant technical experience gained over the years on the factory floor, we have specific technologies for marking technical materials such as flame-retardant plastics, including fireproof plastic LATAMID, flame-retardant PVC, polycarbonate up to Class B1, PEKK, PEI ULTEM, and PC-ABS.

We can also laser mark fire-retardant plastics with excellent quality thanks to special sources that perform "cold" marking, thus avoiding significant thermal shock to the surface of the component being marked.

LASER MARKING SOLUTIONS
FOR ROBOT CELLS

Laser marking and ultra-high productivity technologies, extremely high efficiency to reduce manufacturing costs

The Mini-inline is a protective device that ensures Class I safety without the need for a box, as it is positioned in the system between the laser marker and the component to be marked. This technology was developed in collaboration with a leading multinational automotive manufacturer to mark large metal or plastic industrial components without compromising the speed of a production line.

SAFE

The Mini-inline isolates the laser beam emitted by our laser marker from the work environment. Various safety devices ensure the presence of the Mini-inline and the part to be marked, ensuring Class I safety, as marking is enabled only if the Mini-inline is in proper contact with the part to be marked.

COMPACT AND EASY TO INTEGRATE

Thanks to its small size, the Mini-inline can be easily integrated into a production line: forget about bulky and expensive laser protection structures! Its small size allows it to be placed between our laser marking machine and the workpiece. Together, they form a safe marking unit that can be integrated into any production line.

AFFORDABLE

Compatible with all our laser marking machines with fiber, fiber energy, hybrid, and green sources, unlike a costly and traditional Class 1 laser housing solution, which protects the environment from the laser marking machine, the Mini-inline does not require any major modifications to the production line.

We have already integrated the Mini InLine to laser mark automotive chassis, transmissions, exhaust pipes, engine casings, gearboxes, molded parts, fuel tanks, and aerospace components.
