What We Do
Cutting Capabilities
Pulsed laser cleaning works by delivering short, high-energy pulses that ablate the contaminant layer without touching the substrate beneath. The process is fully controllable — depth, spot size, and pulse energy are tuned to remove exactly the layer you want, nothing more.
Full removal
Rust & Oxide Removal
rust, mill scale, heat tint, black oxide
Remove surface rust, mill scale, and heat-tint oxides from steel, stainless steel, and aluminium. Clean bare metal surface ready for coating, welding, or bonding.
No abrasives
Weld Oxide Removal
heat tint removed, Ra unchanged
Remove blue-black heat tint from stainless steel welds without abrasives. Restores passive layer and corrosion resistance without altering surface texture or Ra.
Layer-selective
Paint & Coating Removal
remove top coat only, or strip to bare metal
Strip paint, powder coat, epoxy, and protective coatings from metal surfaces. Selective by layer — removes only the coating, leaves the substrate and any underlying primer intact if required.
Residue-free

Clean specific zones — weld seams, bonding areas, contact pads, or corrosion spots — while leaving surrounding surfaces untouched. Beam path programmed from your drawing or marked area.
Contamination-free
Pre-Weld / Pre-Bond Surface Prep
surface activated and clean for bonding
Laser cleaning immediately before welding or bonding removes all contaminants that cause porosity, cold lap, or adhesion failure — without introducing new contaminants from chemical or abrasive methods.
Materials & Substrates
Substrates We Clean
Laser cleaning works on any conductive or semi-conductive substrate. The laser removes the contaminant layer without touching what’s beneath — substrate material determines the pulse parameters, not the cleaning outcome.

Where Laser Cleaning is Used
Anywhere contamination, corrosion, or unwanted coatings need to be removed without damaging what’s underneath — laser cleaning replaces abrasive blasting, chemical stripping, and manual grinding.
Welding & Fabrication
Weld Heat Tint Removal
Remove the blue-black chromium oxide heat tint from stainless steel welds. Restores the passive layer and full corrosion resistance without abrasive tools that contaminate the surface with iron particles and alter the Ra value.
Maintenance & Restoration
Rust & Corrosion Removal
Strip surface rust and mill scale from carbon steel structural parts, equipment frames, and fabricated assemblies. Bare metal surface achieved without dimensional loss — ready for immediate re-coating or welding.
Semiconductor & Electronics
Precision Component Decontamination
Remove organic contamination, oxide layers, and adhesive residues from semiconductor tooling, PCB contact pads, and precision fixtures. Chemical-free process with no solvent residue — critical where chemical contamination would compromise downstream processes.
Tooling & Moulds
Mould Cavity Cleaning
Remove mould release agent, polymer residue, and carbonised deposits from injection mould cavities between production runs. Laser cleaning reaches into deep ribs and fine details that manual cleaning cannot access without risk of cavity damage.
Bonding & Adhesion
Pre-Bond Surface Activation
Remove oil, grease, oxide, and release agents from bonding surfaces immediately before adhesive application, gasket sealing, or rubber-to-metal bonding. Laser activation increases surface energy and bond strength without chemical primers.
Aerospace & Marine
Paint & Coating Stripping
Localised paint removal for inspection windows, weld preparation zones, and repair areas on painted structural members. Remove exactly the area needed without disturbing the surrounding coating — no masking, no overspray, no solvent disposal.

What Makes Laser Cleaning Different from Alternatives
Laser cleaning is not just a cleaner version of abrasive blasting — it is a fundamentally different process that solves problems abrasives and chemicals cannot.
Zero Substrate Damage — Guaranteed
Pulsed laser cleaning removes the contaminant layer through a threshold effect: the laser energy is absorbed by the oxide, rust, or coating — not the base metal. Below the ablation threshold of the substrate material, the metal surface is physically untouched. Dimensional tolerance and surface Ra are preserved exactly. No grit embedded in the surface, no stress marks, no chemical residue.
No Consumables, No Waste Disposal
Chemical stripping generates solvent waste that requires licensed disposal. Abrasive blasting generates contaminated grit that must be contained and disposed of. Laser cleaning produces only a fine vapour — extracted and filtered on-site. There are no chemicals to handle, no grit to dispose of, and no secondary contamination of the part being cleaned.
Access to Complex Geometry
Abrasive tools and chemical baths clean surfaces they can reach — deep mould cavities, narrow channels, and internal surfaces are inaccessible or get uneven treatment. Laser cleaning is delivered through a fibre-optic head that can be positioned within millimetres of any surface. We clean weld heat tint inside pipe bores, release agent from deep rib cavities, and oxide from PCB contact pads that no abrasive tool could reach.
Pairs Directly with Our Other Services
Laser cleaning is most valuable as part of a fabrication workflow, not as a standalone service. We clean weld heat tint immediately after TIG welding before passivation. We clean pre-bond surfaces before adhesive application on cut and bent assemblies. We clean mould cavities on tooling we've already machined. The cleaning step is included in the same job order — no separate logistics, no extra lead time.

Clean mill scale and oil from incoming sheet stock for more consistent laser cutting parameters and edge quality.
FAQ
Laser Cleaning Questions
These are some of the common questions customers ask before sending drawings or requesting quotation.
How does laser cleaning work without damaging the substrate?
Pulsed laser cleaning exploits the difference in ablation thresholds between the contaminant and the substrate. The contaminant layer — rust, oxide, paint, adhesive — absorbs the laser energy and vaporises at a lower energy density than the base metal. By tuning the pulse energy below the substrate’s ablation threshold but above the contaminant’s, only the contaminant is removed. The base metal never absorbs enough energy to be altered. This is why the Ra value and surface texture remain unchanged after cleaning.
Can laser cleaning remove heavy rust, not just surface tint?
Does laser cleaning restore the passive layer on stainless steel?
Laser cleaning removes the chromium-depleted heat tint oxide from weld zones, exposing the underlying chromium-rich layer which then re-passivates naturally in air within hours. For applications requiring a documented passivation layer, we recommend following laser cleaning with citric acid or nitric acid passivation per ASTM A967 — this accelerates and certifies the passive layer restoration. We can include passivation in the same job scope.
Can you clean only a specific area, leaving the rest untouched?
Yes — selective area cleaning is one of the primary advantages of laser cleaning over blasting and chemical methods. We program the laser beam path from your DXF outline or from a marked area on the part. The beam stays precisely within the defined zone. No masking tape, no overspray, no risk of chemical damage to surrounding surfaces. Common uses: weld seam only, specific corroded patches, pre-bond zones on painted structures, and contact pad areas on electronic assemblies.
Is laser cleaning safe for aluminium and anodised surfaces?
Laser cleaning on bare aluminium removes the natural oxide layer and adhesive or oil contamination effectively. For anodised aluminium, laser cleaning of the anodised surface itself will remove the anodised layer — so we only clean specific uncoated zones (edges, weld preparation areas, bonding spots) while leaving the anodised surface intact. If you need to clean an anodised part, tell us which zones to clean and we’ll program the beam path accordingly.
What is the turnaround time for laser cleaning?
For standard jobs — weld heat tint removal, light rust removal, adhesive stripping — we typically complete and return parts within 24–48 hours. For large structural assemblies or heavily corroded surfaces requiring multiple passes across large areas, lead time is 3–5 working days. If laser cleaning is combined with other services (welding, polishing, passivation), the overall lead time follows the longest process in the sequence. Most laser cleaning jobs are quoted and scheduled the same day you contact us.
