How laser cleaning works
Laser Cleaning –
How does it work?
Laser cleaning is an industrial cleaning and surface restoration solution that uses the power of concentrated light to remove impurities, coatings, or corrosion. It is a non-abrasive, ecological, precise, and contactless method that respects materials and significantly reduces waste.
Contactless and non-abrasive
No deterioration of treated surfaces, even the most delicate.
Chemical-free
No use of solvents, corrosive agents, or toxic substances.
Clean and localized
Targeted treatment that prevents splashes and any secondary contamination.
Quiet
Low-noise operation, suitable for noise-sensitive environments.
Automated
Technology compatible with automated and robotic production lines.
Precise
Ideal method for sensitive areas or high-value technical parts.
Cost-effective
Reduction in labor, preparation, and residue treatment costs.
Environmentally friendly
Significant waste reduction and minimal environmental impact.
The Principle
Light as a Cleaning Tool
Laser cleaning relies on the use of a highly concentrated light beam, precisely projected onto the surface to be treated. This light is selectively absorbed: surface contaminants (rust, paint, grease, oxidation) strongly absorb the energy, while the base material reflects a large portion of it or absorbs very little.
This difference in absorption causes a rapid thermal elevation in the surface layer, leading to its removal by ablation. Ablation is a physical process by which material is removed by the energy of the beam, in the form of sublimation, vaporization, or delamination, depending on the nature of the contaminant.
This process allows for selective and controlled cleaning, without mechanical contact, abrasion, or chemicals. It ensures optimal preservation of treated materials, even the most sensitive.
Maximum Cleanliness, Minimal Impact
Laser cleaning effectively removes a large majority of contaminants — rust, paint, oxidation, industrial residues — while being safe for the vast majority of surfaces. This advanced technology offers precise treatment, without abrasives or chemicals, making it an ideal solution for sensitive environments or delicate materials.
What contaminants can be removed?
Laser cleaning is particularly effective at removing a wide variety of contaminants, including:
- Rust and corrosion
- Paint, varnish, primers
- Grease and industrial oil
- Oxidation, light or embedded
- Carbon deposits (engines, molds, ducts)
- Graffiti
What materials are compatible?
Laser technology is suitable for a wide range of materials, including:
- Metals: steel, stainless steel, aluminum, copper, brass, bronze
- Natural stone: limestone, granite, marble
- Concrete and bricks
- Wood
A technology adapted to every need
Laser cleaning relies on a precise technical configuration, adjusted for each intervention. The choice between pulsed laser and continuous laser depends on technical objectives, materials, and operational constraints. This flexibility allows for perfect adaptation of the treatment to the nature of the material, the thickness of the layer to be removed, and the desired finish level.
Pulsed Laser
The laser emits very brief but very intense energy pulses. This type of beam allows for precise control of the power applied to each point on the surface.
- High precision on small surfaces
- Suitable for sensitive or technical materials
- Ideal for rust, thin paints, and industrial molds
- Low thermal transfer to the substrate
Continuous Laser
The laser emits a constant energy flow. This type of beam is generally used in automated environments or on very large surfaces.
- Faster for large areas
- Useful for high-volume or in-line production applications
- Requires increased control of generated heat
