Laser marking on metals, plastics, woods and glass

Industrial lasers and laser machines designing and manufacturing are the speciality of ES TECHNOLOGY. Our complete range of lasers (continuous or pulsed, ultraviolet or infrared), allows us to offer our Customers laser marking solutions regardless of their requirements and materials: metals, plastics, ceramics, woods, glass, papers, rubbers, cardboards, etc.

Laser marking is a proven technique of printing. Adding decorations (logos, illustrations, patterns, etc.), data matrix, barcodes, serial numbers and texts makes this versatile technique essential for industrial marking. Laser marking includes the following processes: engraving, selective removal, annealing, color change and foaming. These techniques are chosen depending on materials and marking process.

Laser marking by annealing

The annealing technique for laser marking allows manufacturing material without removal. By the laser beam exposure, material is locally heated to a temperature close to its melting point. Due to the material oxidation, this heating process lead to a colour change, which corresponds to the marking. Depending on laser power, exposure time and material oxides, several marking colours are available.

Laser marking by annealing is only available for metals, especially for titanium and ferrous metals (steel, stainless steel, etc.).

Metals marking

Laser marking by colouring

For marking application by coloring, the laser beam interacts with pigments which were added during the plastic manufacturing. By photoelectric effect, a colour change will follow, turning pigments to grey or black, and thus creating the marking.

Laser marking by colouring is only used for plastics and depends on their composition.

Plastics marking

Laser marking by foaming

For the foaming technique, material is melted by the high energy provided by the laser beam. Small gas bubbles are then generated at the surface, giving a foam aspect and which reflect the light. This technique of marking allows top visual contrast, mainly on dark plastics.

As for colouring, laser marking by foaming is only available for plastics, like polycarbonates.

Woods marking

Laser marking by engraving

This marking technique allows deep impressions (depth up to several mm). The laser beam, focused and with high energy, leads to the material melting and vaporizing, then creating a surface “depression”, the engraving. It is possible to improve the marking visibility by colouring or reflections adding.

Laser engraving is used for all materials: plastics, ceramics, woods, glass, metals, etc.

Glass marking

Laser marking by selective ablation

Laser marking by selective ablation consists, by vaporization, of materials additional coating layers (paints, varnishes, anodizing, etc.) removing. Exposing the part of the initial material allows to create a visible contrast, corresponding to the marking.

As the laser engraving technique, selective ablation is available for all materials.
