 Laser cleaning machine (also known as laser rust removal machine) represents the most high-end industrial cleaning technologies. Laser cleaning machine generates high-density pulsed laser beam which irradiates on the surface of the work piece and removes the rust, dust, oil, grease, oxidation, painting, coating and other contaminants very quickly.

Laser cleaning has the characteristics of non-grinding and non-contact. It has no damage to the substrate. Laser cleaning machine can not only clean organic pollutants like oil, but also remove inorganic substances like metal rust, metal particles, dust, etc. Laser cleaning machine also has the advantages of excellent cleaning effect, high efficiency, low processing cost, simple operation, environment protection and no consumables. This machine is the best choice for industrial cleaning, such as metal surface cleaning, stone cleaning, painting removal, rust removal and so on.

Laser cleaning machine is widely used in all walks of life. Its applications include rust removal on metal surface, oil stains and dirt cleaning, painting and coating removal, pretreatment of welding surface and spraying surface, dust removal on stone statue, cultural relic restoration, rubber mold residue cleaning, etc.

Laser cleaning machine becomes more and more popular in automobile industry, electronics industry, tire industry, shipbuilding industry, rail transit, aerospace, rubber mold industry, construction, cultural relics protection, machinery manufacturing, food processing, petrochemical industry, etc. 

Laser cleaning machine uses laser ablation principle to remove the dust on the metal surface. Laser ablation is a type of physical reaction. When the high-density laser beam irradiates on the metal surface, it is absorbed by the pollution layer on the metal surface. The absorption of large energy forms a rapidly expanding plasma which generates shock waves, and the shock waves turn the pollutants into fragments and remove them off the metal surface. The laser ablation reaction occurs in this way and makes the rust, dirt and oxide layer melt and evaporate very quickly.

Different materials have different properties, so each material has a specific ablation threshold. As long as the energy of laser beam is above the ablation threshold of the dust that needs to be removed, the laser beam can successfully remove the dust. The ablation threshold of rust, oil or painting is much lower than metals like stainless steel, carbon steel, aluminum, etc. Therefore, if the laser parameters are set reasonably, the laser cleaning process will not damage the substrate and leave a very clean surface.

As the laser cleaning machine uses laser ablation to remove dust, there is no consumables required during the laser cleaning process. The traditional industrial cleaning methods like chemical cleaning, ultrasonic cleaning or dry ice cleaning need cleaning reagent to finish the cleaning process, which improves the processing cost and labor cost. Laser cleaning method solves the problem perfectly and it is pollution-free. More and more enterprises prefer use the laser cleaning machine to clean metal parts and restore equipment surface.

  Compared with the traditional industrial cleaning methods, laser cleaning machine has the following advantages: 

1. Non-contact cleaning and no damage to the substrate. The traditional cleaning methods usually contact with the work pieces directly and may damage the surface of the material. Besides, the cleaning agents adhere to the substrate and cannot be removed. Laser cleaning is a non-abrasive and non-contact processing method which solves those problems very easily.
2. No consumables, no chemical agents and environmental friendly. The laser cleaning method is to release laser beam and let the contaminants melt and evaporate, so the laser cleaning doesn’t need any chemical agents and other cleaning agents. The removed rust is small solid powder which is easy to store or recycle. Laser cleaning method has no pollution to the environment and is an ideal way for green cleaning.
3. Excellent cleaning precision and controllable process. Laser cleaning process has high cleaning precision and produces excellent effect on the work piece. It can not only clean flat surface, but also clean curved surface, groove and the inside of pipe. The processed work piece has high cleanliness and no damage. Laser cleaning is automatic and easy to control. The laser output width can be set for precise cleaning. Users can adjust the laser parameters to suit different operating environments and cleaning requirements.
4. Simple and automatic operation. Laser cleaning machine is very easy to install and operate. A handheld laser cleaning machine usually has a compact size and is easy to reach curved surface and complex geometric shapes. Users can hold the cleaning head and clean the specific position on the work pieces per their needs. The cleaning head weights about 2kg-4kg. Also, according to the diversified requirements of users, laser cleaning machine can be hand-held or coordinated with robot to achieve an automated cleaning.
5. High cleaning efficiency and time-saving. The speed of laser cleaning is faster than traditional cleaning methods. A laser cleaning machine can work at 15-30 m2/h speed and perform high quality cleaning at the same time.
6. Reliable laser beam quality and long machine service life. Laser generator has high quality and generates continuous high-density laser beam. With the complete quality control management system and strict machine manufacturing standards, Laser cleaning machine has a long service life and can help users clean various metal parts, molds, equipment and stones for a long time.
7. Low processing cost and low labor cost. Laser cleaning doesn’t need any chemical agents or other consumables, so its processing cost is low. Users just need to provide electricity. Moreover, laser cleaning machine is easy to operate and saves labor cost. Users don’t need to disassemble and move molds when they want to clean the molds. They just need to hold the cleaning head and clean any parts that they want.
