Our expertise in marking technology allows us to offer high-performance laser markers, optimized to ensure precise identification and flawless industrial traceability in every production process.

ABOUT THIS TYPE OF MARKING

Performance and Industrial Integration in COUTH LASER Marking System

At COUTH, we develop laser marking solutions designed for integration and continuous operation in robotic cells and smart production lines. The stability of the laser source and the precision of the galvanometer head ensure consistent marking repeatability and maximum resolution in high-throughput processes.

Industrial laser marking offers superior performance through key operational features:

Mechanically Non-Contact Process

Our laser solutions require no physical contact between the marking machines and the part being marked. This ensures that the material does not suffer deformation or damage during the marking process, even on thin parts.

Photonics-level precision and vector resolution

The automated industrial laser marking process guarantees precise, high-quality results, ideal for components in the automotive, aerospace, rail, and metallurgical sectors.

Permanence and Durability

Laser markings are permanent and wear-resistant, ensuring they will not be erased, fade, or deteriorate over time—making them ideal for applications requiring high durability, such as product identification or industrial traceability.

Compatibility with Various Materials

Our laser markers operate efficiently on a wide range of materials: various types of steel, aluminum, titanium, brass, engineering polymers, ceramics, and various organic composites.

Optimization of Cycle Times

High-speed marking processes that allow marks to be made in seconds, integrating seamlessly into 24/7 continuous production lines and improving efficiency in industrial workshops.

Standardized traceability and security

Laser marking of 2D codes, serial numbers, and logos using our laser solutions ensures the traceability and authenticity of components, in accordance with the ISO/IEC 16022 standard.

Operational Flexibility and Integration

Programmable solutions that allow you to instantly change the part number, shape, size, or marking pattern without line stoppages or physical tooling changes.

No Additional Consumables

Unlike inkjet or pad printing technologies, industrial laser marking equipment requires no inks, solvents, or consumables, reducing the Total Cost of Ownership (TCO) and environmental impact.

COUTH LASER’s laser marking machines combine precision, speed, and technical reliability to deliver maximum efficiency in industrial identification and traceability.

COUTH’s laser marking machines provide direct benefits to plant efficiency and profitability:

  1. High speed and quiet operation: very short and quiet marking cycles, ensuring maximum legibility from the first impact.
  2. Zero consumables and sustainability: Laser marking solutions do not use inks, labels, or solvents, which reduces environmental impact and operating costs.
  3. Capable of adapting even to the most complex marking tasks: at different heights, on geometric and irregular shapes, on cylindrical surfaces, and on moving parts. All of this is possible thanks to the various applications within COUTH LASER’s laser marking range, such as 3D marking, Mark on The Fly, Mark and Read, etc.
  4. Low maintenance and high return on investment (ROI): a robust, long-lasting industrial design that minimizes errors, maintenance, and line downtime while optimizing the return on investment.
  5. Superior readability for machine vision: perfect contrast and permanent marks that comply with traceability standards.
  6. Intuitive integration and operation: industrial laser marking solutions designed for rapid startup and easy communication with plant control systems.

At COUTH, we offer a wide range of laser marking solutions designed to adapt to any production need, combining different technologies with high-precision marking stations.

These are the laser markers we offer:

  • Fiber Laser: designed with high-quality components for integration into high-productivity lines. It offers fast, high-resolution marking on metals and engineering plastics.
  • CO₂ Laser: fast, clean, safe, and consumable-free marking, ideal for organic materials, plastics, minerals, or coated metals on production lines.
  • MOPA Laser: allows adjustment of the pulse and heat input duration across a wide frequency range, providing maximum precision and flexibility depending on the material.
  • Portable Laser: ergonomically designed equipment for direct, on-site marking of bulky or hard-to-reach parts.

 

We also offer several models of laser marking stations:

  • COMPACT & TOP Stations: Class I enclosed cells (EN 60825-1 standard). The COMPACT version (250 x 350 mm) is ideal for small parts, and the TOP version (400 x 300 mm) allows for matrix marking with multiple fixtures.
  • XL Station: Designed for large parts or multiple markings within a 725 x 800 mm area. It features motorized XYZ&W guidance to move the laser head with high precision and safety.
  • Rotary Table Stations: Class I cells for high throughput. They incorporate a two-position rotary indexer (200 x 300 mm) to allow simultaneous loading, unloading, and marking.

COUTH’s laser marking machines are designed for component identification in highly demanding sectors such as automotive, aerospace, electronics, and medical devices. Our laser marking technologies work on steel, aluminum, titanium, brass, and engineering plastics, marking 2D Data Matrix codes, QR codes, serial numbers, and logos without compromising the integrity of the material.

This industrial laser marking process is essential for ensuring individual traceability throughout the product’s entire lifecycle, authentication against counterfeits, and quality control on automated production lines.

The precision of our laser markers allows for the recording of critical information on parts with complex geometries or small dimensions, ensuring optimal optical readability and direct integration into the manufacturing workflow.

As you’ve seen, our laser markers offer great versatility in terms of their use on different materials. Here are the most notable ones:

  • Metals: steel, aluminum, titanium, brass, copper, iron, and alloys such as Zamak.
  • Polymers and engineering plastics: polyamides (PA), ABS, polycarbonate (PC), PVC, PMMA, and plastics with additives.
  • Inorganic and specialty materials: engineering ceramics, glass, and structural composites.
  • Organic materials: wood, cork, rubber-based plastics, etc.

The laser marking process can vary depending on the interaction between the source’s wavelength and the material being marked, with different techniques used depending on the desired result:

  • Annealing: controlled thermal oxidation in the subsurface layer of metals (especially stainless steel and titanium) that produces a high-contrast color change due to the effect of heat, without altering the surface relief or breaking the part’s passivation.
  • Ablation or layer removal: selective removal of the surface coating (paint, coatings, or anodized layers) to expose the base substrate and create visual contrast.
  • Color change / Discoloration: a phytochemical reaction triggered by the heat of the laser beam that alters the material’s pigment.
  • Foaming: surface melting of the polymer that generates microbubbles of gas which refract light, achieving a clear mark on dark plastics.

 

To perform these techniques with maximum precision, our laser markers feature adjustable power sources with standard power levels of 20W, 30W, 50W, 60W, 100W, and 200W (higher power levels can be integrated as required by the process).

Selecting the optimal power depends on the required cycle time, the material’s reflectivity, and the marking depth needed for component traceability.

At COUTH, we have a history in the industry dating back to 1956, dedicated to developing traceability solutions for global manufacturing. Our laser marking machines are designed to meet the highest engineering standards to address the operational needs of your facility, incorporating advanced technology that ensures maximum efficiency and repeatability in every process.
