Laser oil & grease removal

Laser Oil & Grease Removal — Industrial Degreasing

Strip cutting oil, anti-rust oil, release agent and grease off parts without solvents or wastewater. Dry laser degreasing cleans steel, aluminium and composites selectively — often in-line — leaving a clean surface ready for bonding, coating or assembly.

Why move off solvents and baths

Traditional degreasing is wet, slow and regulated

Getting a part clean enough to bond or coat usually means solvents or a wash line — and a tail of handling, drying and waste behind it.

Solvent degreasing

Solvents mean ventilation, PPE, flammability handling and hazardous-waste disposal — slow and tightly regulated.

Aqueous & ultrasonic

Water-based and ultrasonic baths need drying time and generate wastewater that has to be treated.

Drying & handling

Wet processes add dwell, rinse and dry steps that slow the line and add handling between operations.

How dry degreasing works

Lift the oil film, leave a dry, clean surface

The laser delivers energy to the oil or grease film, which vaporizes and is carried off by fume extraction — no solvent, no bath and no drying step. Because it is dry and directed, you can clean just the area that needs it, and run it in-line between operations.

  • Dry process — no solvent, no wastewater
  • Selective — clean only the bonding or coating area
  • In-line capable, no dwell-and-dry step

How completely it cleans depends on the oil type and thickness, the substrate, laser power and scanning width — we confirm it on your part.

What it removes

Oils & films it strips — and from what

The everyday contaminants that stand between a part and a sound bond or coating. Result depends on the oil and substrate, confirmed by testing.

Cutting & machining oil

Residual cutting and coolant oil after machining.

Anti-rust oil

Protective oils applied for storage and transport.

Release agent

Mold release residue on formed and cast parts.

Fingerprint & grime

Handling oils and light grime before assembly.

Suitable substrates:

Steel Aluminium & alloy Composites

Outcome on each substrate depends on the oil type, film thickness, laser power and scanning setup — confirmed by sample testing.

Clean for what comes next

A cleaner surface bonds and coats better

Bonding, welding and coating all fail on a contaminated surface. Dry laser degreasing gives the next operation a clean, oil-free base to work with — without leaving solvent residue of its own.

Better bond adhesion

A clean, dry surface for adhesives and tapes to grip.

Stronger coating prep

Oil-free metal for paint and coating to adhere to.

Cleaner welding

Remove oil before welding for fewer defects. See weld prep.

No residue of its own

No solvent film left behind to interfere later.

Recommended machines

Pulsed for parts, CW for large areas

Detailed parts and selective spots favour pulsed control; large surfaces and high volume lean on continuous-wave throughput.

How the work runs

The workflow, step by step

Dry degreasing to a bond- or coat-ready surface — step by step.

  1. Assess oil, substrate & next step

    Identify the film, the material and whether bonding, coating or welding follows.

  2. Sample test

    We degrease a sample and confirm the surface for the next operation.

  3. Set selective parameters

    Pulsed for parts and detail, continuous-wave for larger areas, cleaning only where needed.

  4. Degrease — often in-line

    Dry, directed cleaning between operations, no bath or drying step.

  5. Inspect readiness

    Confirm an oil-free, residue-free surface ready to bond or coat.

What buyers weigh

Typical project considerations

What process engineers weigh when the part has to bond or coat.

1

Dry, no wastewater

No solvents or wash line, no drying step.

2

Selective & in-line

Clean only the bonding or coating area, between operations.

3

Better adhesion

An oil-free, residue-free base for adhesives and coatings.

4

No film of its own

No solvent residue left to interfere later.

Before you order

Laser degreasing questions, answered straight

Is it clean enough for bonding and coating?
Dry degreasing leaves an oil-free surface with no solvent film of its own, a sound base for adhesives, coatings and welding. Whether it meets a specific bonding or coating spec depends on your process, so we validate it against your requirement on a sample.
Can it remove heavy grease, not just light oil?
Light oils and films clear quickly; heavier or thicker grease may need more passes. How completely it cleans depends on the oil type and thickness, so we test your part and report the result.
Will it harm aluminium parts?
Energy is tuned to the oil film rather than the metal, and pulsed is used where aluminium needs extra care. The outcome depends on the material and settings, so we test before recommending them.
What kinds of oil and grease can it remove?
Cutting and machining oil, anti-rust oil, mold release agent and handling or fingerprint oils are common targets. Heavier or thicker grease may need more passes — how completely it cleans depends on the oil type and thickness, so we test your part and report the result.
Will it damage the base material?
Energy is tuned to the oil film rather than the metal, so impact on the substrate is low and controlled — pulsed is used where aluminium or thin parts need extra care. The outcome depends on the material and settings, so we test before recommending settings.
Is it clean enough for bonding and coating?
Dry degreasing leaves an oil-free surface with no solvent film of its own, which is a sound base for adhesives, coatings and welding. Whether it meets a specific bonding or coating spec depends on your process, so we validate it against your requirement on a sample.
Can it run in-line in production?
Yes — because it is dry and directed with no bath or drying step, it can run in-line and clean only the area that needs it, between operations. We help scope handheld or fixed-head integration for your line.
Can I test it on my own parts?
Send a representative oiled or greasy part and we clean it on the recommended machine, then share the result, settings and cycle data so you can decide with evidence. Start on the contact page.
