How does the process for laser cleaning work?

Laser cleaning is the process of removing contaminants such as rust, oil, oxides, grease or other materials adhering to the base material. A pulsed (nanosecond range) and focused laser beam is directed onto the surface and effects the so called laser ablation. The high power density of our laser systems leads to rapid heating and the formation of a plasma on the surface and thus a sudden removal of the impurities. Due to the extremely high speed of the laser process, the base material remains almost untouched. The radiated energy is concentrated on a very thin layer (approx. 1 µm at 10 ns pulse length). However, higher layer thicknesses are also possible.

Different types of lasers, such as fiber lasers or CO2 lasers, are used to clean surfaces. SLCR Lasertechnik GmbH has built up extensive knowledge in the field of laser applications for surface processing over the past few years and can advise their customers extensively on this.

The selection of the laser source for material processing is made by coordinating the power density and irradiation time according to your processing purpose. With many possible combinations of material and laser radiation, there are large ranges of interaction between the surface and the entering light wave. On the basis of our extensive experience, the parameter study and sample treamtent carried out, we can configure your laser system from a variety of different beam sources, scanners and optics.

Weld seams

Here, the SLCR process helps in the preparation by cleaning the weld seams from oil and grease or removing oxide layers.

Food industry

To maintain consistent baking quality, the various molds can be cleaned with the pulsed SLCR lasers.

Automotive industry

In the automotive industry, the high visual and qualitative demands on the interior require high-quality casting skin molds for the production of the interior trim.

Fiber composite material

Not only for vulcanization molds, but also for molds used in the processing of fiber composites, the pulsed SLCR laser technology systems are ideally suited.

CLEANING OF WELDING SEAMS

The production of high quality welding seams needs a clean preparation and an optimal protection for a long lasting corrosion resistance. At that point the SLCR process helps in the matter of preparation by cleaning of weldings seams from oil and grease or the removal of oxide layers. After the welding process the laser procedure can be used for the cleaning of those welding seams to guarantee a long lasting corrosion resistance.

CLEANING OF BAKING MOULDS IN THE FOOD INDUSTRY

During the baking process, residues remain on the moulds / plates which have to be removed to guarantee a continuous production process. Without this cleaning, the bakery products will stick in the mould and the whole baking machine has to be stopped. Various moulds can be cleaned with pulsed SLCR lasers, to receive a clean surface without residues and a constant baking quality. Due to the high flexibility of these systems it is possible to perform a cleaning inside and outside the baking line. Thus a cleaning in the hot mould continuously and a cleaning in defined time intervals is possible.

CLEANING OF MOULDS IN THE AUTOMOTIVE INDUSTRY

Within the automotive industry, high demands on optics and product quality of the interior, require high-quality casting tools for the production of door panel leatherette, dashboards and other surfaces for car interior. To receive a constant product quality, it is necessary to have a regular cleaning. In the mould cleaning of small and huge areas – no matter whether 2D or 3D geometries – the laser „finds“ and removes the parts residue-free, which do not belong to the tool or mould. In addition to that the laser is able to work quickly and completely.

The mould cleaning can also be used in hot moulds.

CLEANING OF MOULDS OR TOOLS FOR THE PROCESSING OF COMPOSITE MATERIALS

Not only e.g. for vulcanization moulds, as well as for moulds which are used for the treatment of composite materials the pulsed SLCR laser systems can be used to achieve a clean surface. Completely cured composite materials can only be cut with special tools. Diamond-staffed cutters are used for this task. Over the time parts of composite materials stick between the diamonds. They have to be removed for a constant cutting quality. With the help of the pulsed SLCR lasers it is possible to clean the tools completely without damaging the diamonds.
