Background

Laser cleaning & texturing

Laser cleaning is the newest, fastest, most efficient and environmentally conscious method of removing rust, oxides, paint, cleaning welds and other impurities from the surfaces of (mainly) metal and other compatible materials. Using laser technology, we can also roughen the surfaces before applying paints, adhesives, and other coatings.

Laser cleaning and texturing is a good alternative to sandblasting and chemical technologies, as it requires less energy and cleans without consumables such as abrasives or chemicals giving the same final effect. In addition, it leaves no waste material, the surroundings remain clean and is an ecologically completely harmless technology.

 

Laser cleaning and roughening are non-contact methods that require almost no maintenance, leave no waste and require very little energy to operate, offering a very quick return on investment. Despite the fact that in principle it is not dangerous to humans, when using a laser cleaning beam, it is necessary to follow specific safety rules and use the prescribed protective equipment. Therefore, in the investment planning phase, it is necessary to entrust such projects to an experienced team of experts, who are well acquainted with the field of laser cleaning and the relevant regulations. Laser cleaning and roughening, along with the manipulation of workpieces, can be either manual or fully automated processes. Laser cleaning machines are built according to the highest safety standards and must be equipped with an integrated filter unit to remove dust and fumes in order to assure the operator and a safe working environment.


How does it work?

To remove impurities, the laser beam operates in pulses at a high frequency - from 50 kHz all the way up to 1500 kHz. These short pulses create just enough energy for the rust and coatings on the surface we want to remove to evaporate into plasma and burn off.

FerroECOBlast's recommendations

Each material, both the base and the coatings we want to remove, have their own specific properties. The choice of process as well as equipment depends on the correct choice of power, frequency, laser beam modulation options and pulse density.

Many types of laser cleaners are already available on the market today at an affordable price, but the vast majority is limited to more or less successfully removing rust, grease and maybe paint. Other coatings, such as various plastic coatings, ceramic coatings, Kevlar, composites or carbon fibre based materials and various galvanic coatings are not as easy to remove and require a lot of knowledge and experience.

The correct and safe extraction and filtration of sometimes extremely toxic components, released into the atmosphere during the plasma phase, are often neglected. There are few providers of laser cleaning systems who warn their customers about this issue, as most of them do not offer these solutions or do not know them well enough.

To avoid buying a simple laser cleaner, which is by no means cheap and in the end will not solve your problem, a consultation with experts such as FerroECOBlast Europe is more than encouraged.
