Laser Cleaning

Precise, Clean, and Contact-Free Surface Treatment with Laser Technology

Laser cleaning is a contactless and highly efficient technology that removes rust, paint, coatings, oxides, or contaminants without chemicals, abrasives, or manual labor. It is widely used across various industries due to its precision, speed, and minimal environmental impact.

Cleaning Surfaces with Laser –
Your Benefits in the Spotlight

Precise
Removes only the contamination layer, preserving the base material – even on delicate or complex surfaces.
Powerful & Fast
High-speed scanning allows for rapid processing, reducing downtime and labor costs.
Clean
No chemicals, abrasive media, or water needed – resulting in a dry, residue-free process.
Eco-Friendly
Generates minimal waste and eliminates the need for hazardous cleaning agents.
Versatile
Can be integrated into automated production lines or used as a mobile, handheld system for field applications; works effectively on a wide range of materials.
Low Operating Costs
Minimal maintenance and no need for consumables like sand or solvents.

Cleaning Surfaces with Laser – How it works

Laser cleaning uses a focused laser beam that causes surface contaminants like rust, paint, or residue to absorb the energy, evaporate or break apart and lift off – while the base material remains unaffected. The method is highly precise and localized, perfectly suited for delicate components and intricate surfaces. To ensure thorough and even cleaning, the laser beam is moved across the surface using a scanning system, typically with galvanometer scanners (galvo heads). These fast-moving mirrors direct the beam in controlled patterns –such as lines – covering the target area efficiently. The scan speed, beam intensity, and pattern are all adjustable, enabling optimized cleaning for different materials and contamination levels.

Laser beam hits the surface

Our lasers emit light in short pulses in the nanosecond range. The process is gentle on the material, as the heat input to the workpiece is reduced to a minimum.

The radiation heats up the oxid layer

Our lasers work with a wavelength of approximately 1064 nm. This light is well absorbed by layers of dirt or paint, but not by the workpiece.

The surface is cleaned by blasting off the contamination

Accessories such as our extraction system remove particles directly from the workpiece and from the air, making the laser process very clean.
