Which Materials Can Be Used for Laser Cleaning?

Laser cleaning machine using high-frequency high-energy laser pulse irradiation of the surface of the workpiece, so that the surface of the oil stains, rust spots or coatings instantaneous evaporation or stripping, the surface of the workpiece attached to the surface or the surface coating can be removed at high speed and effective cleaning material, so as to achieve the object to clean and cleaning process. With no damage to the parts matrix, no consumables, energy saving and environmental protection, etc., to meet the industrial processing areas of complex modeling, fine positioning of the cleaning requirements, to achieve a higher degree of cleanliness of the cleaning effect and lower overall cost of production benefits.

Suntop laser production of laser cleaning equipment is a new generation of surface treatment of high-tech products, easy to install, simple operation, high degree of automation. Simple operation, power on, no chemicals, media, dust and water can be cleaned. It can be cleaned according to the curved surface with high cleanliness of the cleaning surface. Stains, dirt, rust, coatings, coatings and oxidized layer, widely used in ship, auto repair, rubber mold, high-end machine tools, rail, environmental protection and other industries.

The main driver for laser cleaning applications is the market demand for non-toxic, non-abrasive cleaning methods that can be used as an alternative to previously used chemical, manual and abrasive jet cleaning methods.

Laser Cleaning Applications:

1. Surface polishing and rust removal in steel manufacturing

1) Rusting occurs when metal is exposed to moisture and reacts with water to form ferrous oxide. This rusting degrades the metal and makes it unsuitable for use in many applications.

2) On the other hand, as a result of the heat treatment process, an oxidized layer is formed on the surface of the metal. The oxidized layer discolors the surface of the metal, thus hindering subsequent finishing operations.

2. Cleaning of anode parts

1) The presence of dirt and other contaminants increases the resistance of the anode resulting in more battery power consumption.

2) The presence of contaminants also shortens the life of the anode by increasing the rate of consumption during the smelting process.

3. Preparation of metal bonding

1) In order to improve process stability, surface adhesion and better weld quality, the surface of the metal material to be joined must be prepared before applying welding and other joining techniques.

2) Without the necessary cleaning of the metal material surfaces, joints and seams are prone to degradation, increased wear, and even catastrophic failure.

4. Pre-brazing treatment

1) It helps to remove ferrous and non-ferrous metals, lubricants and other contaminants from metal and aluminum surfaces in preparation for high quality soldering.

2) It also ensures smooth and non-porous brazed seams.

5. Partial removal of coatings

1)It can be used on virtually all surface types, whether chemically anodized, oxide or organic coatings

2)Laser cleaning for automotive and other industries removes coatings and paints while maintaining the integrity of the substrate.

6. Selective Paint Removal

The use of lasers for polishing, surface cleaning and coating removal is rapidly expanding. Depending on the application, the laser pulse frequency, energy and wavelength must be precisely selected to clean, polish and ablate the target material. At the same time, any form of damage to the substrate must be prevented. At present, laser cleaning technology is mainly used for the cleaning of small parts. Of course, it is highly likely that this technology will also be applicable for cleaning large surfaces and large equipment/structures. With the current progress in the field, these visions are expected to become a reality in the near future.
