Advantages of laser cleaning technology

Tyre moulds are an important tool used in the tyre production process (the curing process). The tyre moulds have a number of treads (corresponding to the pattern of the tyre) which, over a long period of time, produce many deposits such as sulphide, inorganic substances, silicone oil, carbon black, etc. Therefore, they need to be cleaned regularly to ensure the cleanliness of their surface. However, due to the irregularity and complexity of the mould tread pattern, the usual cleaning methods are not in place and some parts can form dead spots of contamination, thus affecting the quality of the tyre.

At present, the main methods used for tyre mould cleaning are mechanical cleaning, chemical cleaning, dry ice cleaning, ultrasonic cleaning and laser cleaning with radium heat. In the past decade, laser cleaning has developed rapidly and gradually replaced other cleaning methods in many fields. So, what are the advantages of laser cleaning technology?

1. high efficiency

Radium thermal laser radiation to the surface of the mould, will be absorbed by the deposits on the surface of the mould. Under the action of high temperature energy, the deposit instantly vaporises and evaporates from the surface of the object, and the time required is very short. In contrast, traditional cleaning methods, such as ultrasonic cleaning, have to go through preheating, cooling and other processes before cleaning, which takes a long time. And for a daily production of thousands of tyres production enterprises, laser cleaning technology is clearly the most efficient.

2. Reliable

The laser beam can reach areas that are not easy to remove for cleaning, and the cleanliness is higher. Moreover, laser cleaning is non-contact cleaning and no solvents or substances are added during the cleaning process, so that no damage is caused to the mould under the right process parameters (optical parameters of the laser). Compared to traditional mechanical and chemical cleaning methods, it is more reliable.

3.environmental protection

Laser cleaning is the use of high energy beam, without the use of any organic solvents, so no pollution, but also no noise, harmless to the human body and the environment. On the other hand, all kinds of environmental protection laws and regulations have been landed and implemented one after another, and environmental protection manufacturing has gradually become normalized. In such an environment, laser cleaning technology is undoubtedly the most suitable.

With the continuous development and maturity of relevant supporting equipment and technology, the future application of laser thermal laser cleaning technology will be more and more industries.
