Although traditional cleaning can also perform cleaning operations on the surface of workpieces to a certain extent, with the increasingly stringent environmental protection laws in China today, traditional cleaning is gradually being phased out.

　　The main problems with traditional cleaning methods include:

　　1. Negative impact on the environment and wear on the substrate.

　　2. The sandblasting system generates a large amount of waste and can damage the fine surface of the substrate.

　　3. Cleaning with chemical solvents generates potentially hazardous steam and liquid waste.

　　The traditional method of cleaning molds is labor-intensive, inefficient, low safety factor, and high cost. The shortcomings of traditional cleaning methods have promoted the application of laser technology in the field of surface cleaning. Due to the many advantages of laser cleaning, it has now become the most effective method to remove unwanted substances on the surface of materials.

　　The principle and application of laser cleaning:

　　The principle of laser cleaning is to use a high-frequency short-pulse laser as a cleaning solution for the working medium. The high-energy beam of light of a specific wavelength is absorbed by the rust layer, paint layer, and pollution layer, forming a rapidly expanding plasma, and at the same time generating a shock wave. The shock wave turns the contaminants into fragments and is removed. The substrate also does not absorb energy, does not damage the surface of the object to be cleaned, and does not reduce the surface finish.

　　Laser cleaning can remove the rust layer, coating, paint layer, oxide layer, etc. on the surface of the workpiece, and can be applied to metal or non-metal workpieces. Since laser cleaning is a non-abrasive, non-contact, and non-thermal cleaning method, it will not cause damage to the surface of the workpiece. Laser cleaning equipment can be used in the aerospace industry, shipbuilding industry, rail transit industry, automobile manufacturing industry, steel manufacturing industry, and electronics industry, among others.
