Laser Paint Removal

Laser paint removal is a process through which a paint layer is removed from a surface without damaging the substrate. It’s also known as laser coating removal and de-coating. The laser beam is pulsed onto the part with a precise energy density: it is higher than the paint ablation threshold, but lower than the substrate ablation threshold. As the paint is vaporized, the surface is left intact.

The process can be applied to any metals, although the most typical applications are steel and aluminum. It can be used for most types of coatings, including powder coating and e-coating. Laser cleaning can also be used for other applications like mold cleaning, rust removal, and surface preparation.

Why Choose Laser Technology for Paint Removal?

Damaging metal surfaces while removing paint is costly. It can increase your scrap rate or diminish the life span of your structures. Unlike other paint removal methods, laser surface cleaning can be fine-tuned for paint removal—and only that.

For Production Lines

Automotive manufacturers reported to us that up to 5% of their parts such as wheels, brake pads, and fenders have minor paint defects during the manufacturing process. Scrapping those parts is expensive.

Laser paint stripping is a great solution for high-volume productions. As opposed to abrasive blasting alternatives, laser cleaning is completely automated and doesn't need maintenance between parts.

This eliminates preparation time for each part, which reduces the average time spent on each part. As a result, paint removal isn’t the bottleneck in your production line.

For Refurbishing Applications

Expensive equipment must be treated with caution to avoid diminishing its life span. Laser paint stripping is a great choice for refurbishing expensive structures such as electrical towers and power plants (e.g., nuclear, hydro, or gas). It's also great for vehicles such as planes, ships, submarines, and trains.

To Strip Paint With Micron Precision

Paint stripping applications that demand precision cannot be performed by manual blasting. Laser cleaning works in a different order of magnitude than abrasive blasting methods: its precision is calculated in microns. It delivers the accuracy you need for applications like logo etching and data matrix etching (also known as marking by removing).

To Create a Safe Workplace

Safety hazards in the workplace can result in injuries, long-term sickness, and even death. Paint removal must be safely integrated to avoid any issues on the shop floor.

Some paint stripping methods have more inherent security risks than others. For example, if you want to remove a coating using abrasive media blasting, you must set up a room that meets the following requirements:

  • A ventilation system must be installed to protect workers from exposure to toxic and hazardous waste
  • Workers must wear equipment for respiratory, hearing and body protection
  • Appropriate measures must be taken to share safety-related information (training sessions, stickers, etc.)

Managing fewer safety issues means fewer potential risks in your workplace. Laser cleaning is a lot simpler to implement than mechanical and chemical alternatives. You must only consider one potential risk: depending on the type of coating that you need removed, you may or may not have to manage hazardous fumes. 

Laserax provides custom integration services. This includes integrating ventilation systems near the laser cleaning machine, if necessary. This way, you don't have to worry about a safe integration. Our laser machines are always guaranteed 100% safe according to international safety standards.

To Use Your Workers Efficiently

What if you could use your workers to do the tasks for which you hired them? To perform more important tasks than replace consumables like disks, water, sand, or dry ice? Or what if you could simply reduce the number of workers you need?

Alternatives like sandblasting and shotblasting require operators to manually blast painted surfaces. Operators are also needed for regular maintenance like replacing consumables.

But your workers can be used more efficiently. With laser surface cleaning, coating removal is completely automated and, as such, doesn't need operators or consumables. It's a cost-effective operation that follows cycle times.

High-Power Fiber Laser Systems

Laserax manufactures high-power fiber laser systems specifically designed to remove coatings from metal surfaces, most commonly steel and aluminum surfaces. Laser energy is released in short pulses and at a set repetition rate. The pulsed laser thus generates shockwaves that eject coatings from metal surfaces.
