About cleaning

Laser cleaning technology is an alternative to mechanical and chemical methods where there is a need for environmentally friendly disposal of used liquids and materials. The laser is capable of cleaning a wide range of metallic materials from surface dirt (rust, varnish, oil). Cleaning does not damage the base material as it may be with conventional dry ice, blasting, or sandblasting methods. There is no additional waste (water, sand, abrasive, chemistry). After laser treatment, it is not necessary to further adjust the surface for subsequent painting.

More information

Laser systems combine performance and versatility with the lowest operating costs for industrial dirt removal. Systems distribute thousands of ultra-short laser pulses per second into a dirty surface. The pulsating laser beams are linearly arranged side by side. Most laser energy is absorbed by the surface layer and is instantly transformed into thermal energy that causes evaporation of impurities from the surface of the base material. In this way, the layer of unwanted dirt is effectively removed from the substrate.

Laser cleaning is a fast, clean, environmentally friendly and safe technology while maintaining all the strength characteristics and basic structures of the base material.


Laser cleaning is applied in many fields:

  • In the plastics and rubber industry (automotive) for mold cleaning, but also for whole machines or tools.
  • Cleaning of oil deposits in the food industry where there are high demands on cleanliness.
  • Removal of oxides originating from processes in the electro-industry
  • Restoration of historical objects – the laser is very suitable for cleaning rugged and complicated products. Parts of veteran car engines, coin processing, cleaning of any historical objects. Clean the whole body from old varnish or rust
  • Cleaning sandstone stoneware. Stone historic objects, historic buildings, statues, etc.

Other applications:    

  • Removal of rust from metallic materials
  • Removal of organic impurities from plastics and composite components
  • Preparation for surface treatment
  • Removing scalded layers after the plating and painting process
  • Selective removal of corrosion layers as a preparation for welding
  • Finishing of welds – removal of color
  • Degreasing metals before soldering or welding
  • Degreasing metals before joining
  • Structuring and modification of the metal surface
