Class 4 laser marking machines, as defined by international laser safety standards, are systems that operate without a protective enclosure. This means the laser beam is exposed during operation, providing direct access to the marking area. These machines are ideal for production environments where flexibility and open access are essential.
Unlike Class 1 systems—which require fully enclosed housings—Class 4 lasers can mark directly onto large parts, complex shapes, or hard-to-reach surfaces, without physical limitations.

Class 4 laser systems are the best option for companies that need:

• Full application freedom: no need to fit parts into a sealed cabin.
• Greater marking range: work directly on large assemblies or structures.
• Seamless integration: ideal for marking-on-the-fly and automated production lines.

Moreover, these machines typically have lower overall costs than enclosed systems, offering an excellent balance of price, performance, and productivity.

• Maximum flexibility: mark directly on large, heavy, or complex parts.
• Material versatility: suitable for metals, plastics, coated surfaces, electronics, and more.
• Compact and modular design: quick and easy to install on any workstation or production line.
• Full automation compatibility: perfect for industrial production environments.
• Advanced control with Datasoft software: intuitive interface with powerful job management features.

Since Class 4 lasers operate without an enclosure, additional safety measures are required:

• Certified laser safety goggles must be worn.
• The working area must be clearly marked and restricted.
• Safety interlocks, warning signs, or curtains may be needed in automated setups.
• Operators should be trained in safe handling and procedures.

At Datamark, we offer complete safety guidance to ensure your Class 4 laser installation complies with current CE regulations and workplace standards.

Thanks to their power and versatility, Class 4 laser marking machines are widely used in a variety of industries, including:

• Automotive: VIN marking, structural parts, engine components.
• Aerospace: identification of turbine parts and flight-critical components.
• Metalworking and machining: marking large assemblies, serial numbers, and logos.
• Electronics: precise marking of circuit boards, connectors, and housings.
• Medical devices: permanent marking of surgical instruments and stainless steel parts.
• Jewelry and watchmaking: fine engravings on precious metals and decorative surfaces.

Datamark offers Class 4 laser systems in three different technologies to cover a wide range of materials and industrial needs:

• Fiber laser: ideal for metals, technical plastics, and high-speed industrial marking.
• UV laser: perfect for delicate materials, such as plastic components, glass, and semiconductors.
• CO2 laser: best suited for marking organic materials like wood, leather, cardboard, and some plastics.

Datamark Class 4 laser systems are available in two main configurations:

• Desktop models with an adjustable mounting stand, designed for manual marking stations or workbenches.
• Integration-ready modules for automated production lines, compatible with robotic systems, conveyors, and PLCs.

Both formats offer the same high-performance laser capabilities and are built for industrial environments.

Datamark offers a complete range of Class 4 laser marking systems, engineered for high-demand industrial applications. All models are equipped with robust industrial housings, top-grade optical components, and are operated through our powerful and user-friendly Datasoft software.
