Laser Cleaning
Laser Cleaning is an innovative technique that uses a laser beam, deflected by a scanning head, to remove a superficial layer of material and thus clean the product surface at an easily adjustable depth without direct contact. The ability to clean complex surfaces with a high degree of precision and the intuitive operation make Laser cleaning one of the most efficient industrial technologies. Furthermore, the possibility of setting a cleaning threshold enables selective ablations by choosing which material to remove. The use of high-energy pulsed laser sources ensures rapid processing execution, optimal for large-surface products. The complete absence of consumables or chemical substances to dispose of makes it eco-friendly, easy to manage and cost-effective in the long term.
The sectors of greatest interest for Laser Cleaning applications are: mold cleaning (post process), post welding cleaning (pre and post process), contact cleaning in the electronic field (for example pre-process cleaning of the air pins of electric motor windings), post-printing cleaning of inks on anilox of press printing machines in the packaging sector, removal of paints and coatings for treatments and rework, etc.

Laser cleaning applications
Pre-processing cleaning
One of the main processes that use laser cleaning is linked to the pre-process surface treatment or before carrying out a second process. Some of the main reasons are:
- the removal of rust or other oxides from metallic materials,
- the preparation of surfaces for subsequent welding,
- the removal of oils or fats
Post processing cleaning
A second important use of laser cleaning is for post-processing of materials, i.e. cleaning after the piece has already been processed. Among these we can mention:
- Cleaning of the weld seam from oxides and residues
- Cleaning of chips and residues of parts that are particularly difficult to reach, such as molds
- Removal of oil and grease residues from processing
Removal of paints, inks, coatings, sheaths or films
A final use of laser cleaning technology is related to the removal of paints or other materials fixed on a substrate. We can cite as an example:
- The removal of paints or coatings from pieces to be reworked (spot repairing);
- The removal of insulating sheaths or films in the electric or electronic field;
- The removal of inks in the field of printing machines;

Metal Laser Cleaning: advanced solutions for Industry
Laser cleaning is mainly used for metal parts but there are applications that use it for some types of plastics or for other materials that require pre or post treatment after manufacturing.
Laser cleaning of metals is today one of the most innovative and precise technologies for removing contaminants, oxidation, and coatings from metal surfaces. This method offers significant advantages over traditional techniques, ensuring excellent results without compromising the integrity of the base material.
Advantages of Laser Technology to Clean Metal
Using a laser for metal cleaning makes it possible to achieve levels of precision unattainable with conventional methods. The process is fully controllable, allowing the adjustment of intensity and parameters according to the type of material and the required cleaning level. In addition, this technology eliminates the need for chemical solvents and abrasive materials, drastically reducing environmental impact and operating costs.
The main features include:
- Selective cleaning without damaging the metal substrate,
- No chemical residues or abrasive particles,
- Precise control of the treatment area,
- Significant reduction in processing time,
- Compliance with the strictest environmental regulations.
Specialized Metal Laser Cleaning operations
The versatility of laser technology makes it possible to handle different types of contaminants and coatings.
Laser paint removal is one of the most requested applications, allowing complete removal of paint layers without compromising the underlying material. This technique proves particularly effective for surface preparation prior to new treatments or for the restoration of metal components.
Laser degreasing offers an innovative solution for removing industrial oils and greases, with widespread application in the industrial mechanics and automotive sectors, where precision cleaning is essential to ensure adhesion of subsequent treatments.
Furthermore, laser technology excels in rust removal, enabling the recovery of surfaces damaged by oxidation.
Specific applications for types of Metals
Stainless steel
Stainless steel particularly benefits from the use of laser metal cleaning, especially in the removal of surface oxidation and contaminants that can compromise its anticorrosive properties. In the food, pharmaceutical, and chemical industries, where hygienic standards are crucial, this technology ensures perfectly clean surfaces without altering the material’s characteristics.
Aluminum and light alloys
For aluminum, a laser metal cleaner provides the ability to remove oxidation, machining residues, and paint without compromising the natural protective layer. In the aerospace and automotive industries, where weight is a critical factor, this technology allows the mechanical properties of light alloys to remain unaltered. In specialized applications, laser technology can also be used for the selective removal of anodization, a less common but technically feasible process for specific industrial needs.
Special steels and high-strength alloys
Special steels used in critical applications require particular care during cleaning operations. A laser metal cleaner allows millimetric precision, removing specific contaminants without altering the metallurgical properties of the material. This aspect is crucial in the oil & gas, energy, and precision tooling sectors.
Sectors of use of laser cleaning
The sectors of greatest interest for Laser Cleaning applications are: mold cleaning (post process), post welding cleaning (pre process and post process), contact cleaning in the electronic field (for example pre-process cleaning of the air pins of electric motor windings), post-printing cleaning of inks on anilox of press printing machines in the packaging sector, removal of paints and coatings for treatments and reworking, etc.
Why prefer a laser cleaner to other technologies
Laser cleaning compared to other technologies offers important advantages that must be considered when choosing.
Contactless processing
Laser processing makes it possible not to use parts in contact with the piece, making them ideal for materials or products that require careful processing. Furthermore, as there are no contact parts, there are no related wear and maintenance costs (no consumables).
Respect for nature (Green)
The laser cleaning process is environmentally friendly and does not use chemical material that must then be disposed of.
Modern laser cleaning systems consume less than a household appliance and certainly much less than many competing technologies, thus emitting less CO2 into the environment and being more respectful of nature.
Processing quality and precision
Laser cleaning are characterized by the quality and precision of the workmanship. It can be used for high precision cleaning even for highly technological sectors or with high contamination requirements such as medical.
Versatility
The possibility of processing any type of material, the easy integration on systems and lines and the digital nature of the Laser management process make it flexible to adapt to any process and suitable for highly customized products.
