Laser Paint Removal

Laser paint removal is an environmentally friendly process used to remove paint layers from surfaces without damaging the substrate. It’s also known as laser coating removal and de-coating. 

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, e-coating, and phosphate coating. Laser cleaning can also be used for other applications such as laser rust removal, oxide removal, mold cleaning, and surface preparation.

How Does Laser Paint Removal Work?

Laser paint removal works through a process known as laser ablation. Laser energy is released in short pulses at a set repetition rate. In doing so, the pulsed laser generates shockwaves that eject coatings from metal surfaces when they reach their ablation threshold. 

As the paint is vaporized, the surface is left intact.

Why Choose Laser Technology for Paint Removal?

    Replace Part Masking

    Manufacturers in the automotive industry spend a lot of time and labor masking parts. This slows down the coating process and often leads to quality issues.

    Laser paint removal is much more effective and can be integrated inline in high-volume automated productions without slowing them down. All you need to do is coat the entire part, then let the laser remove paint from the areas you want.

    Selectively Remove Paint

    Paint stripping applications that demand high precision cannot be performed by sandblasting. This is the case when preparing areas for welding or assembly. With laser cleaning, you can strip paint and other contaminants with micron precision to produce high-quality parts.

    Avoid Damaging The Metal Surface

    Damaging metal surfaces while removing paint is costly. It can increase your scrap rate or diminish the quality of your parts. Unlike other paint removal methods, laser surface cleaning is a non-contact process fine-tuned to remove paint without affecting the metal.

    Minimize Maintenance

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

    This eliminates preparation time, which reduces the average time spent on each part. As a result, paint removal does not become a bottleneck in your production line.

    Create a Safe Workplace

    Some paint stripping methods have more security risks than others. 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 may only have to manage fumes, depending on the type of coating removed. 

    Laserax provides custom integration services. This includes integrating fume extraction systems when needed. This way, you don't have to worry about a safe integration. Our laser machines are guaranteed 100% safe according to international safety standards.​

Industries that Benefit from Laser Paint Removal

Powertrain & drivetrain systems

Automotive Industry

While masking is traditionally used in the automotive industry, laser cleaning is a more efficient and cost-effective solution that is gaining in popularity.

Many parts are coated, painted, phosphated, or laminated to improve material properties. These coatings need to be absent from certain areas before assembly, welding or bonding.

Automotive sectors that benefit from laser paint removal include Foundry, Casting, Drivetrain, Powertrain, E-Drive, Seating, Stamping, Battery, and E-Motor.

Agriculture Industry

Agriculture and heavy equipment manufacturers are increasingly replacing masking with laser cleaning. While part masking is slow and expensive, laser cleaning offers a high return on investment and can keep up with a high production pace.

Parts that benefit from laser cleaning include castings, drivetrains, powertrains, seat rails, stampings, and more.

Aerospace Industry

During maintenance of aircraft parts, coatings need to be removed before being refurbished. Compared to blasting methods, laser technology is an environmentally friendly alternative that is safer for operators.

The cost of aerospace parts and high-quality requirements make laser technology a worthwhile investment.

Other Industries

Laser paint removal is an emerging technology that is precise and efficient. It offers endless possibilities and can be used for applications in a variety of industries.
