Absorption, not impact
The pulse is tuned so the layer to remove absorbs it and the substrate reflects or ignores it. Nothing hits the part mechanically.
TECHNOLOGY · HOW IT WORKS
The coating absorbs the energy. The metal does not.
Laser cleaning and dry ice blasting remove what sits on top of a surface without grinding the surface itself. Here is what that means in practice, and where each one stops making sense.
01
Four principles
The same four hold for both technologies — they are what makes the process repeatable.
Parameters on record
Power, frequency, speed and passes are fixed per substrate and written down, so a second intervention reproduces the first.
Test before production
Every job starts on a sacrificial area of your own part. If the result is not right, we adjust before touching anything that matters.
Extraction at the source
What comes off is captured and filtered at the point of contact. No enclosure, no abrasive to sweep up afterwards.
02
Laser, dry ice and sandblasting
The same surface-preparation job, three processes with very different consequences for the substrate, the facility and the budget.

ADJUSTED PER PART AND COATING
ADJUSTED PER PART AND COATING
| CRITERION | LASER CLEANING | DRY ICE | SANDBLASTING |
|---|---|---|---|
| Contact with the part | None. No abrasion | Soft pellet, non-abrasive | Continuous abrasive impact |
| Effect on substrate | No measurable thickness loss | No wear; watch thermal shock | Wear; deforms thin aluminium |
| Waste generated | Dust only, extracted and filtered | The removed layer only; CO₂ sublimates | Spent sand, grit and sludge |
| Containment | Confined area, no enclosure | Confined area; ventilation required | Containment enclosure |
| Masking | Minimal. Zone by zone | Minimal | Full masking |
| Consumables | None | Dry ice pellets | Abrasive, filters, nozzles |
| Layer selectivity | Layer by layer, tunable | Surface layer | All or nothing |
| 3-year cost | Lower: no abrasive, no disposal | Moderate: pellets only | Higher: consumable + disposal |

Operating conditions
What we need from your facility, and what we bring ourselves.
COND-01
Confined work area
A cordoned zone with controlled access while the beam is live. Other crews keep working outside it.
COND-02
Power and access
A standard industrial supply and a door the unit can pass through. The part stays where it is.
COND-03
Filtered extraction
We bring extraction and filtration. Removed material leaves as filtered dust, not as loose media.
