Mold is an indispensable component in modern industrial production. Sulfide, oil stain and rusty spots will form on the mold after long-term work, which will result in the burr, dimension instability, etc. of the produced products. The traditional methods of mold washing include mechanical, chemical, ultrasonic cleaning, etc., which are greatly restricted when meeting environmental protection and high precision application needs.Laser cleaning technology uses a high-energy laser beam to irradiate the surface, rendering the instantaneous evaporation or stripping of the surface dirt, causing high speed and effective dirt removal. It is a pollution-free, noiseless and harmless green cleaning technology. S&A chillers for fiber lasers provide laser cleaning equipment with a precise temperature control solution. Having 2 temperature control systems, suitable for different occasions. Real-time monitoring of chiller operation and modification of chiller parameters. Resolving mold dirt problems with laser cleaning equipment, can highly improve production accuracy and efficiency, and bring more benefits to industrial manufacturing.
