In industrial cleaning, laser cleaning is undoubtedly one of the most fascinating methods in the world. Similar to dry ice blasting, it is of great importance to ensure the correct application of the process. Each manufacturing process is unique and therefore requires a customized cleaning method. It is crucial to understand the advantages and disadvantages of different cleaning methods and select the most effective method to make your production processes safer and more economical. Laser cleaning is particularly suitable for automated use.
This innovative technology is characterized by extremely low noise emissions, making it virtually silent. In addition, this method completely dispenses with the use of solid abrasives, meaning that laser cleaning systems can be operated independently of raw materials. This also completely eliminates the annoying disposal of residual materials.
The gentle and non-abrasive processing of the surface means that it is not damaged. This not only guarantees high quality results, but also saves costs for any repairs. The operating costs are also extremely low and the maintenance intervals are particularly long, which has a positive effect on the total cost of ownership.
Laser cleaning systems can be easily automated online. This makes work processes more efficient and saves time. In addition, cleaning a surface with a laser guarantees precise results that meet the highest demands. With our technology, you are therefore ideally equipped for the future.
White Lion offers two extremely powerful and forward-looking solutions for different areas of application and materials with its dry ice and laser cleaning methods.
When using a laser, impurities are removed from layers on the surfaces of components by high-energy vaporization, allowing maximum precision and processing speed to be achieved through customizable parameters. Residues can be neutralized, making laser cleaning extremely environmentally friendly.

The use of mobile laser cleaning has numerous advantages over other methods. The process and implementation of the laser beam method is as follows: A generated laser beam is directed at the runway surface in the touch down zone. Due to the frequency of the laser, only the material to be removed reacts to the beams and vaporizes or burns when the laser beam hits it. The resulting vapours are immediately absorbed by an extraction system and neutralized by a catalyst. An ultrasonic system measures the thickness of the rubber layer before and after cleaning and documents the cleaning success. This data is recorded for quality control purposes and provides information on the condition of the runway.
The operating costs of a laser system are noticeably lower compared to the conventional method. Handling is also more convenient. These two factors make it possible to use the laser system more frequently than the water jet printing method. Weekly or even daily cleaning is possible and may be desirable in order to keep the runway surface evenly clean. In this way, cleaning contributes to the safety of the landing process and flight operations, as the best possible traction is guaranteed at all times. The cleaning laser can be used in all weather conditions as it penetrates water, ice or snow. It also works perfectly at temperatures below freezing.
The innovative laser system for removing rubber abrasion from roads is based on a specially equipped vehicle with various technical components. These include a powerful mobile laser that effectively removes the material to be removed. In addition, ultrasound systems are integrated to precisely measure the layer thickness before and after cleaning. An extraction system ensures that the residues are safely removed and the exhaust gases are filtered. The vehicle is also equipped with a computer system that reliably archives the measurement data and thus enables complete documentation of the cleaning processes. This modern laser system not only ensures maximum efficiency in the removal of rubber abrasion, but also uses environmentally friendly and precise cleaning technology.
Laser cleaning is a convincing, fast and optimal method for industrial cleaning that is extremely precise and efficient. Compared to other cleaning methods such as dry ice blasting, laser cleaning offers numerous advantages such as low operating costs, high precision and environmental compatibility. This method is used in various industrial sectors, from cleaning food baking tins to removing paint in the aerospace industry. By using robots, workpieces can be cleaned automatically, quickly and thoroughly, leading to consistent and reliable results. As no abrasives are required, there is no waste product and laser cleaning enables cleaning with low operating costs. Laser cleaning ensures a high level of reproducibility when cleaning surfaces. Overall, laser cleaning presents itself as a pioneering technology for industrial cleaning processes that impresses with its environmental friendliness, precision and efficiency.

When aircraft land at airports, intensive rubber abrasion occurs on the surface of the runway, especially from the main landing gear. The larger and busier the airport, the faster a layer of rubber builds up on the runway, which must be removed regularly for safety reasons. Rubber abrasion on runways significantly impairs braking in wet, snowy or slushy conditions. A thick layer of rubber makes it difficult for water to run off through the grooves in the runway and means that the tires barely touch the asphalt or concrete. This can lead to dangerous “hydroplaning”, which makes it impossible to control the aircraft. Viscous hydroplaning in particular occurs with a thin film of water on heavily contaminated runways at various speeds and has been involved in a number of accidents. The heaviest contamination with rubber is found in the “touch down zones”, the area of the runway where the airplanes touch down. This large area is usually around 900 meters and needs to be cleaned regularly, especially at large commercial airports every 14 days.
This process of removing the contaminants is usually carried out using water jets. Rotating high-pressure nozzles remove the rubber abrasion and the excess water, together with the dissolved material, the rubber waste, is collected by a vacuum truck and disposed of.
This method is associated with certain costs and limitations. On the one hand, it is expensive as special equipment is required. It is also dependent on the weather, which can lead to delays. Furthermore, this method is abrasive to the track surface, which can lead to wear in the long term. In addition, there are long cleaning intervals and disposal costs for rubber waste.
Clean dryer fabrics and fabric webs with a consistently high cfm value are crucial for a smooth production process in modern paper manufacturing. White Lion fully understands the concerns of paper manufacturers: an online system must be reliable and extremely efficient – both in terms of the cleaning results of the components and the operating costs. The solution is an online system with a laser source – laser cleaning!
Processing is dry, contact-free and the system can be used in the dry and wet sections independently of raw materials. Fibrous materials, sticky substances – the typical impurities that reduce the cfm value – can be evaporated with high energy and at variable production speeds without restrictions! The special feature is that the specially developed dryer fabric does not react to the laser beam and therefore cannot be damaged.
Laser cleaning is completely contactless and noiseless – the machine remains clean.
Compared to conventional cleaning methods, laser cleaning is not only convincing due to the possibility of online operation, but also due to its dryness and independence from raw materials. Thanks to the precise work of the laser beam, the energy used has a maximum cleaning effect on surfaces. The operating costs remain low and the cfm value high. However, the outstanding properties of laser cleaning are not only used in the paper industry. There are also laser cleaning solutions for a common problem in aviation – soiling of the touch-down zone.
