Laser cleaning can be used not only to clean organic contaminants, but also to clean inorganic materials, including metal corrosion, metal particles, and dust.
The following describes some practical applications. These technologies have been very mature and have been widely used.
Every year, tire manufacturers in the world manufacture hundreds of millions of tires, and the tire molds in the production process must be quickly and reliably cleaned to save downtime.
Conventional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, but these methods usually have to be cooled in a hot mold for several hours, then moved to the cleaning equipment for cleaning, cleaning takes a long time, and easy to damage the accuracy of the mold Chemical solvents and noise can also cause problems such as safety and environmental protection.
The use of laser cleaning methods, because the laser can be transmitted using optical fiber, so it is very flexible in use; because the laser cleaning method can be used to connect the optical fiber to the blind corner of the die or difficult to clean the parts to be cleaned, so easy to use; due to rubber and Without gasification, no toxic gas will be produced, which will affect the safety of the working environment. The technology of laser cleaning tire molds has been widely adopted in the tire industry in Europe and America. Although the initial investment cost is high, the benefits obtained in saving standby time, avoiding mold damage, working safety, and saving raw materials can be quickly recovered.
The anti-adhesive elastic film layer on food industry moulds needs to be replaced regularly to ensure hygiene. The use of laser cleaning without chemicals is also particularly suitable for this application.
