Why laser cleaning?

A non-contact technology that replaces sandblasting, chemical pickling and grinding - with no waste and no damage.

Zero damage to the substrate

The laser beam is absorbed by the contamination and reflected by the metal. The base surface stays intact, even on delicate parts.

100% environmentally friendly

No chemicals, no abrasive, no waste to dispose of. The only "emission" is vaporised particles collected by the extraction unit. Meets the strictest environmental standards.

Up to 70% faster

Wide-scan head with a cleaning width of up to 200 mm. One operator with a laser replaces a sandblasting crew - no preparation and no clean-up.

Precise targeting

You can clean exactly the selected area. The rest of the surface stays untouched. Ideal for spot repairs and restoration.

Zero consumable costs

No consumables - no sand, chemicals or abrasive. The only cost is electricity. The laser source lasts up to 100,000 hours.

Touch control panel

Intuitive screen that stores up to 10 cleaning programmes. Adjust power, frequency and scan width - match the laser to the task in seconds.

Power options

Match the power to the task

We supply lasers from precise pulsed units to industrial continuous-wave ones. We will recommend the best option.

100-300W
Pulsed MOPA

Gentle cleaning of moulds, tools and electronic components. Precise control, minimal heat input.

500W
Pulsed

Removing rust, paint and coatings from machine parts and automotive components. The all-round choice.

1000-1500W
CW (continuous)

Cleaning steel sheet, structures and frames. High throughput for mid-sized industry.

2000W+
Industrial CW

Heavy-duty work: ship hulls, pipelines, bridges, tanks. Maximum cleaning speed.

What do we clean?

Laser cleaner applications

Rust and corrosion removal

Deep and surface rust, oxides, corrosion deposits. Returns the metal to a clean state without affecting the material structure.

Paint and coating removal

Stripping old lacquers, powder coatings and electroplated coatings without damaging the substrate. Ideal before applying new coatings.

Weld preparation

Cleaning zones before and after welding. Removing oxides, oils and contamination gives better weld quality.

Mould and casting cleaning

Precise removal of deposits from injection, casting and vulcanising moulds. Extends tool life without dismantling.

Restoration and conservation

Gentle cleaning of historic elements, architectural monuments and works of art. Controlled power does not damage the original structure.

Degreasing

Removing grease, oil and fatty contamination from precision parts before assembly, bonding or welding.

Rust removal with a laser

Removing rust from a metal surface in real time. No chemicals, no damage to the substrate.

Process

How does laser cleaning work?

01

Laser beam

The laser emits a concentrated, high-energy beam of light directed at the contaminated surface.

02

Ablation

The contamination (rust, paint, oxides) absorbs the laser energy and vaporises. The metal reflects the beam - it is not damaged.

03

Extraction

Vaporised particles are collected by the extraction system. Zero solid waste, zero chemicals in the air.

04

Clean metal

The surface is ready for welding, painting or further processing. Clean, smooth and free of contamination.

FAQ

Frequently asked questions

Does the laser damage the surface being cleaned?
No. The laser beam is absorbed by the contamination (rust, paint, oxides) and reflected by clean metal. With correctly selected power the substrate stays intact. That is why the technology is used even in the restoration of historic objects.
Which laser power should I choose?
It depends on the application. For precise cleaning of moulds and electronics: 100-300W (pulsed). For general rust and paint removal: 500W. For heavy industry: 1000-2000W (CW). We will recommend the best option after discussing your needs.
Which materials can be cleaned?
Carbon steel, stainless steel, aluminium, copper, titanium, cast iron and their alloys. The laser effectively removes rust, paint, lacquer, oxides, oil, grease and corrosion deposits.
Are consumables needed?
No. A laser cleaner uses no sand, chemicals, discs or any single-use materials. The only running cost is electricity. The laser source has a lifetime of up to 100,000 hours - more than 11 years of continuous operation.
Is the technology environmentally friendly?
Yes - it is one of the most environmentally friendly cleaning methods. No chemicals, no abrasive, no solid waste. Vaporised particles are collected by an extraction system with a filter. It meets the strictest EU environmental standards.
How long does deployment take?
The unit is ready to work as soon as it is connected. Operator training takes a few hours. The intuitive panel with pre-programmed cleaning profiles lets you start work straight away.
