Laser cleaning

Laser cleaning has become increasigly popular thanks to being fast, flexible and safe.

We offer both high-end and economical solutions from the world leading laser manufacturers, as well as our own ROD mobile laser cleaning machine, tried and tested in all kinds of settings.

We are ready to:

  • help you choose the best solution for your needs
  • invite you to our offices and showroom in Praha (Prague)
  • design and install the new system, including integration into an existing production line
  • provide necessary training, safety equipment and documentation
  • provide both regular servicing and any repairs and spare parts needed

You can visit our showroom in Praha and get acquainted with the cleaning lasers and the cleaning process. We also take cleaning orders – if you just need something cleaned or want to see samples before buying a laser machine, don’t hesitate to contact Mr. Boháč. We have done a wide variety of orders, from cleaning vintage motorcycle parts for a restoration project to an in situ cleaning of an industrial oil storage tank.


How does it work?

The flexibility of lasers is currently unrivaled; cleaning lasers can be used to remove oxides from metal surfaces (rust removal being one of the most popular applications), grease and fatty residue (food industry, machine parts, renovations), to clean injection moulds, stripping of old paints and varnishes etc. Oxide removal and degreasing is also part of surface preparation for welding, glueing or varnishing.

The thin layer of oxides, fats, finishes or grime is selectively destroyed and evaporated with a focused laser beam. Ultra short laser pulses (μs-ms) heat the layer up, creating heat induced high pressure, resulting in evaporation. The fumes may be potentially toxic, depending on the composition of the cleaned layer, and a suitable ventilation and fume extraction system is usually recommended.

Despite the high temperatures and pressure involved, the cleaning laser, when set properly, has no damaging effect on the cleaned material. It’s safe for the most sensitive applications like cleaning of polished and etched metal (e.g. plastic injection moulds). It is also fast, relatively noiseless (compared to sanding, sandblasting or dry-ice blasting) and environmentally friendly.


Laser cleaning is:

  • precise, easily adjustable for a wide variety of applications
  • fast
  • environmentally safe & friendly – no additional chemicals necessary
  • non-damaging to the cleaned surface
  • low-cost: the operations costs are the lowest compared to other industrial cleaning technologies (less than 1 EUR/hour)
  • low-maintenance

Both CO2 and fiber lasers are suitable for cleaning:

CW CO2 laser: wavelength 10.6 microns, peak power up to 5000 W
Fiber laser: wavelength 1.06 μs, peak power up to 1000 W


Most demanded applications:

Injection mould (plastic moulding, rubber moulding) cleaning

Polyurethane mould cleaning (release agent removal, PUR foam residue removal)

Glass mould cleaning

Cleaning of titanium slabs in pharmaceutical industry

Varnish & paint stripping, partial stripping before further processing (soldering, welding, finishing)

Cleaning of anilox printing cylinders in flexography (ink residue removal)

Weld cleaning

Food industry: cleaning of baking sheets, tools, storage tanks, smokehouse equipment

Stone and wall cleaning (facade restoration, graffiti removal, restoration of statues)

 

Pricing:

Prices vary depending on the specifications and custom adjustments requested; from approx. 25 000 EUR to 380 000 EUR (for a fully automated robotic station with a 1000 W laser).
