Whether for the paint stripping of metal parts, the selective cleaning of components or the preparation for post-processing - the process is versatile, efficient and ideal for automated production processes.
What is laser paint stripping?
In laser paint stripping, paint, colour or coating is removed from the surface using highly focused laser beams - without damaging the base material. The energy of the laser dissolves the coating thermally or by ablation, turning it into particles or vapour.
Typical applications range from localised paint removal to the complete paint stripping of complex components. The stripping of cathodic dip painting (CDP) coatings using laser technology offers a highly precise and economical alternative to conventional paint stripping processes such as blasting or chemical stripping.
Advantages of laser paint stripping at a glance
- Non-contact process - no mechanical stress
- Precise & selective cleaning - ideal for sensitive or structured surfaces
- No chemicals - environmentally friendly and safe for employees
- No abrasive residues - clean processes, less reworking
- Can be automated - ideal for series production and inline integration
- Low operating costs - no consumables such as abrasives or solvents
Typical areas of application
- Removal of powder coating, paint or primer on aluminium, steel, stainless steel, galvanisedmetals, composite materials(partially, depending on absorption)
- Paint stripping for repair and restoration
- Preparation for welding, bonding or measuring processes
- Exposure of contact surfaces in electrical engineering
Technology & process details
Our systems utilise depending on the application:
- Fibre laser (1064 nm) - powerful and universally applicable
- Short-pulse or ultrashort-pulse lasers - for fine, sensitive surfaces
- Scanner or gantry technology - adapted to geometry and cycle times
The power, pulse rate and focus diameter of our laser systems are precisely adapted to the material, paint quality and coating thickness - to achieve optimum cleaning quality without damaging the substrate.
A particularly demanding area of application for laser paint stripping is the preparation of contact surfaces for electrical connections. In many industrial applications - for example in automotive engineering, power electronics or mechanical and plant engineering - certain areas of a component must be free of the cathodic dip coating to ensure reliable electrical conductivity. Cathodic dip-paint coatings have an insulating effect and prevent the safe flow of current or the formation of permanent contact connections, e.g. for earthing points, earthing rails or screw connections with a conductive function. With laser technology, these contact surfaces can be stripped with high precision, reproducibly and without damaging the base material. The laser specifically removes only the coating, while the underlying metal surface is cleanly exposed. This is crucial for the quality and long-term stability of the electrical connection. Thanks to the non-contact processing, even sensitive or complex geometries are easily achieved - without any masking or post-processing. The process parameters can be precisely customised to the respective material combination, which guarantees controlled and reliable exposure. In this way, laser-based paint stripping not only ensures optimum electrical contacts, but also makes a significant contribution to process reliability and quality in series production.

Why rely on lasers?
Laser paint stripping not only saves time and money, but also meets strict environmental regulations and the requirements of modern, digitalised production lines.
A one-off investment in a laser system permanently reduces operating costs - without any chemicals, storage costs or disposal costs.
