There are patterns and logo patterns in the mold, which are relatively delicate carving processes. However, the mold is repeatedly used under high pressure and high temperature, which is inevitably polluted by the comprehensive deposition of rubber, compounding agent and release agent used in the vulcanization process (the main pollutants are sulfide, inorganic oxide, silicone oil, carbon black, etc.).

It is easy to accumulate rubber and residues in patterns, grooves, etc., which will affect the surface shape of the tire to a certain extent, thus making the product defective or scrap. Therefore, the mold must be cleaned regularly to ensure the cleanliness of its surface, so as to ensure the quality of the mold and the service life of the mold.

On the other hand, there is an annual demand of tens of billions of goods manufactured with molds all over the world. The cleaning of molds in the production process must be rapid and reliable to save downtime. The traditional chemical cleaning method, high-pressure water cleaning method, dry ice method and so on all have the disadvantages of high labor intensity, low efficiency, low safety factor and high cost. Therefore, the manufacturing industry urgently needs an efficient, low-cost, cleaning technology. Laser cleaning technology has the advantages of high efficiency, low cost, and no damage to the mold. At the same time, it can realize the online cleaning operation and ensure the safety of the operator. Compared with the traditional cleaning method, the use of laser cleaning greatly improves the cleaning quality and cleaning efficiency, solves the problems existing in the traditional cleaning method, and fully meets the requirements of rapid and reliable tire cleaning.
