Industrial Laser Cleaning
Service in Switzerland.
Industrial laser cleaning is a dry, contactless way to strip rust, paint, oxide and coatings from metal parts and production equipment. We bring the mobile unit to your site anywhere in Switzerland, so large or fixed assemblies never leave the floor. A pulsed fiber laser removes only the unwanted layer, which makes industrial laser cleaning a precise option for surface preparation and parts cleaning.

What industrial laser cleaning is
and how it works
The method is laser ablation. A pulsed fiber laser fires short, energy-rich pulses at the surface. Rust, oxide, paint, oil and other contamination absorb that light, heat past their ablation threshold within microseconds and leave the part as gas and fine particles. Clean metal reflects most of the same wavelength and stays cool, so the geometry, hardness and finish of the part do not change.
Because each contaminant has its own absorption, the operator tunes pulse energy, frequency and scan speed to the job. A light oxide film lifts in a single pass, while a thick rust scale or a multi-layer coating is taken down in stages. This level of control is what separates a laser cleaning service from blasting or chemical stripping, where the whole surface is attacked at once.
An extraction unit with a HEPA filter sits at the point of work and captures the dry debris before it can spread. There is no slurry, no spent abrasive and no chemical run-off to neutralise. What you are left with is the original surface, ready for inspection, welding, bonding or coating straight away.
Remove the contamination,
leave the metal intact
Pulse 1 hits the oil and dust on top. Loose grease and machining residue absorb the light at once, heat past the ablation threshold and lift off as gas and fine particles. The metal underneath stays far cooler than your hand would feel.
Pulse 2 works through the oxide and rust. Each layer has its own absorption, so the operator can stop at a defined depth or continue with another pass down to bare metal.
Pulse 3 reaches the bright metal. Here the balance flips: clean steel reflects the wavelength, so the process self-limits and removal stops. The substrate keeps its geometry, and the surface is ready for the next step.

on your site
Mobile laser cleaning makes sense whenever dismantling, transport or downtime would cost more than an on-site visit. We work directly on the part and set up within about half an hour. The pulsed fiber laser, the control unit and the extraction form one compact system that runs on standard site power.
Our service area covers the whole country, from Lake Constance to Valais, all 26 cantons. The usual lead time is a few working days from confirmation, with faster slots for urgent line stops. Depending on the power level we need either a 230 V or a 400 V connection on site, which we confirm with you before the visit.

Industrial parts cleaning
and surface preparation
Industrial parts cleaning
On components, assemblies, molds and tooling, the laser removes oil, carbon, oxide and old coatings without touching the base metal. Because the process is contactless, there is no media to lodge in threads, blind holes or fine geometry, and tight-tolerance parts keep their dimensions.
This suits maintenance and overhaul work where a part has to be cleaned in place, between production runs, or before it goes back into an assembly. We clean steel, stainless steel, aluminium and cast iron, from small precision parts up to large weldments and machine beds.
- Components, assemblies, molds and tooling
- Oil, carbon, oxide and coating residue
- No media trapped in threads or blind holes
- Tolerances and surface finish preserved
Surface preparation done right
Before bonding, sealing, coating or welding, the surface needs to be clean and active, not just visually clear. The laser creates a defined, repeatable surface by removing oxide, mill scale and release agents and exposing fresh metal, so the next process can grip properly.
For welding, we clean and prepare seams so the joint is free of oxide and discolouration before the next pass. See our dedicated page on laser weld cleaning for joints and weld seams.
- Defined, repeatable surface profile
- Pre-treatment for bonding, sealing and coating
- Pre-weld preparation of seams and joints
- Clean substrate for inspection and NDT
Our laser cleaning services
Rust and oxide removal
Flash rust, scale and heavy oxide taken off steel and cast iron down to bright, sound metal.
Paint and coating removal
Paint, powder coating and primer lifted layer by layer, with no strippers and no abrasive media.
Weld cleaning and pre-weld prep
Oxide and heat discolouration cleared from seams, and joints prepared before the next weld pass.
Mold and tool cleaning
Release agent, resin and carbon build-up removed from molds and tooling between production runs.
Degreasing and oil removal
Oil, grease and machining residue cleared from parts before inspection, bonding or assembly.
Scale and discolouration
Mill scale, tarnish and weld colour removed while the base metal keeps its hardness and finish.
For focused jobs we also run dedicated pages: laser rust removal, laser weld cleaning and laser paint removal.
