Don’t let old cleaning methods slow you down! SLTL’s Fiber Laser Cleaning Machine wipes out rust, paint & grease with speed, safety & zero chemicals. Industries worldwide are already switching, don’t be the last to upgrade!
Cleaning is something we do every day – but in industries, it’s far more complicated. It’s not just about removing dirt; it’s about eliminating rust, grease, paint, oxides, and residues that affect how machines, vehicles, and structures work.
Traditionally, industries have used methods like sandblasting, chemical baths, or manual scrubbing. While effective in some ways, these methods are often messy, expensive, unsafe, and harmful to the environment.
That’s why industries around the world are turning to laser cleaning – a technology that uses concentrated light beams to clean surfaces with unmatched precision and efficiency. Among the leaders in this field is SLTL Group, whose Fiber Laser Cleaning Machine is redefining how cleaning is done in factories, shipyards, and even heritage sites.
What is Laser Cleaning?
Laser cleaning uses a high-powered laser beam to remove unwanted material from a surface. The laser beam doesn’t physically touch the object – instead, the unwanted layer (like rust, grease, or paint) absorbs the laser’s energy and either evaporates into tiny particles (for thin contaminants), or cracks and flakes off (for thicker coatings).
The beauty of this method is that the underlying surface remains intact and unharmed. For example:
- Rust is removed from a steel beam without grinding down the metal.
- Paint is stripped from a car panel without scratching it.
- Oxides are cleaned from battery terminals without affecting their performance.
- It’s like having an eraser made of light that removes only the unwanted layer.
Technical Highlights of SLTL’s Laser Cleaning System
- Pulsed Laser: 50-300 W: Best for precision cleaning (like battery poles, molds, or electronics).
- Continuous Wave (CW) Laser: 1000-2000 W: Best for large-scale, heavy-duty cleaning (like ship hulls or rusted machinery).
- Wavelength: 1064 nm (near-infrared light, perfect for most industrial materials).
- Beam Range: Works effectively at 50-150 mm from the surface.
- Cooling System: Available in both air-cooled and water-cooled versions.
- Power Supply: Standard 100-240V AC (50/60 Hz), making it compatible across industries worldwide.
- Operating Temperature: 5°C – 40°C
- Humidity: 10% – 95% (non-condensing)
Key Advantages:
- No consumables (no sand, water, or chemicals needed)
- Cost-effective in the long run
- Works at high speed with robust results
- Non-contact and eco-friendly
- Minimal heat effect (doesn’t harm the base material)
- Ready for automation and robotics
Where Can SLTL’s Laser Cleaning Be Used?
Laser cleaning is not limited to one field – it’s transforming multiple industries at once. Here’s a breakdown of applications from the brochure with added explanations:
1. Battery Cleaning Automation
- In electric vehicles, battery poles need to be oxide-free for safe welding.
- SLTL’s laser cleaning machine uses vision systems to detect the poles, clean them precisely, and prepare them for welding.
- This reduces processing time, ensures better bonding, and prevents costly product recalls.
2. Laser Paint Removal
- Removes paint from metals like steel, aluminum, and copper, as well as from non-metals like glass.
- Unlike sanding or chemicals, it leaves the base surface smooth and intact.
- Useful for automotive body shops, aerospace maintenance, and repainting projects.
3. Conservation and Restoration
- Used for cleaning monuments, statues, and heritage buildings.
- Gently removes grime, soot, and deposits without damaging delicate stone or marble.
- Eco-friendly, since there’s no chemical runoff.
4. Naval Applications
- Ships, submarines, and offshore structures suffer heavy corrosion due to seawater.
- Laser cleaning removes rust, paint, and marine growth quickly.
- Being a seawater-compatible solution, it’s widely adopted in shipbuilding and naval maintenance.
5. Die-Mold Cleaning
- In manufacturing, molds accumulate grease, oil, and oxide that affect product quality.
- SLTL’s laser cleaning restores molds quickly, reducing downtime and maintenance costs.
6. Automotive Industry
- Cleans engine parts, rims, and frames.
- Removes rust and dirt to enhance performance and extend lifespan.
- Prepares surfaces for painting, welding, or coating.
7. Other Key Industries
- Aerospace: Cleaning aircraft parts with precision.
- Food Processing: Removing contaminants from equipment without chemicals.
- Power Generation: Cleaning turbines and parts.
- Electronics & Semiconductor: Cleaning tiny components safely.
- Oil & Gas: Rust and coating removal from pipelines and rigs.
- Construction & Sheet Metal: Preparing steel and metal surfaces for fabrication.
What Can the Machine Remove?
The SLTL Laser Cleaning Machine can handle almost any contaminant or deposit, including:
- Rust and corrosion
- Paint (including selective paint removal)
- Oil and grease stains
- Oxidation layers
- Anodized coatings
- Scale, salt, and soil deposits
- Road grime on machinery
- Galvanized zinc staining
- Mold residue
- Stone pollution layers
It can even perform surface conditioning and texturing, which improves adhesion for coatings or welding.
Why Choose Laser Cleaning Over Traditional Methods?
Here’s how SLTL’s solution stacks up against older techniques:
| Method | Problems Faced | Why Laser Cleaning Wins |
| Sandblasting | Creates dust, damages surfaces, noisy, needs abrasive material | Clean, precise, no consumables |
| Chemical Cleaning | Toxic waste, costly disposal, unsafe for workers | Eco-friendly, safe, no waste |
| Manual Scrubbing | Slow, inconsistent, labor-heavy | Fast, repeatable, automation-ready |
| Water Blasting | Messy, risk of water damage, disposal issues | Dry, clean, easy waste handling |
Safety and Eco-Friendly Design
SLTL has made safety and sustainability a priority:
- Non-contact process: No mechanical stress on the part.
- Minimal heat effect: Base material stays safe.
- No hazardous waste: Unlike chemicals, nothing toxic is left behind.
- Noise-free operation: Much quieter than blasting methods.
- Fume extraction system: Keeps the air clean for workers.
This makes it not only good for business but also good for the planet.
