Tire molds are an important tool to be used in tire production (vulcanization). There are some patterns in the tire mold (corresponding to the texture of the tire). Long-term use will produce a lot of deposits, such as sulfide, inorganic, silicone oil, carbon black and so on. Therefore, regular cleaning is required to ensure the cleanliness of the surface. However, due to the irregular and complicated pattern of the mold pattern, the general cleaning method is not cleaned in place, and some parts will form a dead corner, which will affect the quality of the tire.
At present, the methods used for tire mold cleaning mainly include mechanical cleaning, chemical cleaning, dry ice cleaning, ultrasonic cleaning, and Laser Cleaning. In the past decade, laser cleaning has developed rapidly, gradually replacing other cleaning methods in many fields. So, what are the advantages of laser cleaning technology?
After the laser is radiated to the surface of the mold, it is absorbed by the deposit on the surface of the mold. Under the action of high-temperature energy, the time required for the vaporization of the deposit to vaporize off the surface of the object is very short. The traditional cleaning method, such as ultrasonic cleaning, can be cleaned after preheating, cooling, etc., and takes a long time. For a tire manufacturer with thousands of daily production, laser cleaning technology is clearly the most efficient.
The laser beam can be cleaned at a location that is difficult to remove, resulting in a higher degree of cleanliness. Moreover, the laser cleaning is non-contact cleaning, and no solvent or substance is added during the cleaning process, so the mold is not damaged under the appropriate process parameters (the optical parameters of the laser). More reliable than traditional mechanical cleaning, chemical cleaning and other methods.
Laser cleaning is a high-energy beam that does not require any organic solvents, so it is non-polluting and noise-free, and is harmless to the human body and the environment. On the other hand, various environmental laws and regulations have been implemented and implemented one after another, and environmentally friendly manufacturing has gradually become normalized. In such an environment, laser cleaning technology is undoubtedly the most suitable.
