What Is The Working Principle Of The Laser Cleaner? Which Industries Can I Apply To?

Apr 01, 2019

The working principle of the laser cleaning machine is basically the same as that of the laser marking machine. It is mainly used to ablate the surface of the product by rust, coating, oil stain and other surface substances generated by the laser beam on the surface of the product. Laser cleaners are used in a wide range of applications and are basically suitable for any industry.


The laser cleaning machine uses a high-energy-density laser beam to illuminate the surface of the workpiece to instantaneously evaporate or peel off the dirt, rust or coating on the surface, thereby achieving a clean, green, energy-saving and high-efficiency industrial tool. The practical application can quickly remove the paint. Derusting, removing oxides, oil stains, oil stains and product residues, restoration and preservation of historical relics. The laser cleaner removes the surface deposits or surface coatings of the cleaning object at high speed to achieve a clean process. It is a new technology based on the interaction between laser and matter. It is different from the traditional mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method (wet cleaning process). It does not need any CFC organic solvent that destroys the ozone layer, and it is non-polluting. It is noise-free and harmless to the human body and the environment. It is a true green cleaning technology.


How the laser cleaner works

1. Generate various laser beams by different types of lasers.

2. The energy density of the laser can be adjusted to allow the dirt to expand by heat. When the expansion force of the dirt is greater than the adsorption force of the dirt on the substrate, the dirt will leave the surface of the object.

3. The laser beam can generate several thousand degrees or even tens of thousands of degrees of high temperature near the focus, so that the dirt instantly evaporates, vaporizes or decomposes.

4. The divergence angle of the laser beam is small and the directivity is good. The laser beam can be integrated into the spot of different diameters by the concentrating system.

Laser cleaning machine application areas:

 The metal or glass surface coating is removed and the paint is quickly removed.

 Rapid derusting, and various oxides.

 Remove grease, resin, glue, dust, stains, and residue.

 Roughening of metal surface

 Stripping before demolition or before bonding, derusting, degreasing, oxide after welding, residue treatment.

 Mold cleaning, such as tire molds, electronic molds, food molds

 Removal of oil after production and processing of precision parts

 Rapid cleaning of nuclear power component repairs

 Aerospace weapons, oxide treatment, paint removal, rust removal during ship production or maintenance

 Narrow space metal surface cleaning

 Cultural relics cleaning, rock cleaning, cleaning of exterior surfaces of buildings.
