Laser Paint Removal is an ablative process whereby laser energy is focused and absorbed by the surface, resulting in vaporization of the coating with minimal effect to the underlying substrate. This process can be applied to various materials including metal, plastics, composites and glass.
A clean surface – this is the basic requirement for successful and durable welding and adhesive connections. However, before joining, components often have paint and functional layers. The laser provides a remedy for this: the non-contact tool frees components of functional layers within seconds. And it does this only in areas where joining is meant to take place, for example, or where the functional layer is no longer needed. Here’s how it works: pulses with high peak pulse power evaporate the wafer-thin layers, without affecting the component.
Subsequent processes such as joining can then be carried out faster, more homogenously, and are entirely reproducible. The connections are clean and last longer. Joining preparation work using light as a tool can also integrate seamlessly into industrial series production, due to the fact that data can be easily transferred via interfaces.
What is 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 Laser Paint Removal Works
Laser paint removal works through a process known as laser ablation. Laser ablation works by sending nanosecond laser pulses into a surface, creating shockwaves that eject contaminants or turn them into gas. Laser cleaning can effectively clean the target surface without harming any substrate layers or surrounding material. We’ll help you find and calibrate the cleaning laser in order to optimize it to your cleaning needs.
What are the benefits of laser paint removal?
There are many advantages of Laser Paint Removal. They can provide you with deep clean, shine and protection against future stains and there is no harmful chemicals used which means they are safe for all those that are sensitive to other solutions. They can be used to restore high gloss surfaces, such as walls and floors.
Stripping with a laser does not require any additional blasting agents or chemical substances which would prove elaborate and expensive.
Reproducible and precise
The laser enables controlled paint removal, precise down to the micrometer – easy to reproduce and extremely precise.
Laser paint removal represents an almost wear-free technology as no mechanical tool is subjected to wear and tear.
Gentle on the material
While alternative methods to laser cleaning such as sandblasting can damage the surface of the component, the laser operates gently, leaving absolutely no residue.

Industries That Benefit From Laser Paint Removal
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 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.
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.
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.
