There are various cleaning methods for traditional cleaning industrial equipment, mostly using chemical agents and mechanical methods for cleaning. In today's increasingly strict environmental protection regulations and increasing awareness of environmental protection and safety in China, the types of chemicals that can be used in industrial production cleaning will become fewer and fewer. How to find a cleaner and non damaging cleaning method is a problem that we have to consider. Laser cleaning has the characteristics of no grinding, non-contact, low thermal effect, and is suitable for cleaning objects of various materials, and is considered the most reliable and effective solution.
 

In the production process of car tires, molds are important mechanical equipment. The quality of the mold directly affects the quality of the tire. The surface of tire molds will have carved patterns or other patterns, and the molds are often used in high temperature and humidity environments. Therefore, there will be a lot of rubber or other residues left in the grooves of the inner molds. When accumulated to a certain extent, it will affect the appearance and structure of the molds, ultimately leading to the production of defective products. Therefore, maintaining the cleanliness of tire molds is particularly important.

Technology has changed life, and traditional tire cleaning is very troublesome. However, since the advent of laser cleaning machines, tire cleaning has become easy, simple, and convenient. Mold is an important tool used in the tire vulcanization process, and it is inevitably contaminated by the comprehensive deposition of rubber, compounding agents, and release agents used during the vulcanization process. Repeated use can cause some pattern pollution dead zones. Therefore, it is necessary to regularly clean the mold to ensure its surface cleanliness.

There are two traditional cleaning methods for tire molds:

Mechanical cleaning method

Using manual sandcloth or steel wire physical grinding and dry sandblasting, different combinations of cleaning can be selected according to needs.

advantage:

1. A mature technology widely adopted by the tire industry.

2. Simple and easy to operate, with low requirements for equipment and tools.

disadvantages:

1. It can cause mechanical damage to the mold and shorten its lifespan.

2. Sandblasting treatment can easily block the exhaust holes of the mold, and the workload of clearing the exhaust holes after sandblasting is significant.

3. Causing high labor intensity and long cleaning cycles.

Chemical cleaning method

Chemical cleaning methods mainly include: organic solvent method, melting method, acid washing method, alkali washing method, etc

advantage:easy to use and low cost.

disadvantages:Long term use of the above methods can cause mold corrosion, directly affecting the appearance and quality of the product. At the same time, these pharmaceutical raw materials pollute the environment and damage the health of operators. Therefore, it is necessary to have complete labor protection measures and pollutant treatment equipment.

Principle and advantages of laser cleaning tire molds

Laser cleaning of tire molds technology is a process that utilizes the characteristics of high energy, high brightness, and good directionality of lasers to destroy the force between pollutants and object surfaces, thereby removing pollutants without damaging the substrate.

Laser cleaning of tire molds is a process of selective evaporation of dirt on the surface of laser cleaned materials. Different materials have different laser energy absorption rates for specific wavelengths. When the absorption rate of the attachment on the surface of the material is greater than the absorption rate of the substrate, laser irradiation can instantly raise the temperature of the attachment above the melting point and cause gasification. The resulting surface interface gasification phenomenon does not damage the substrate as it cannot reach its melting point.
