Dry Ice Cleaning

Contamination on mold surfaces can have various causes and must be eliminated in order to produce molded parts with high quality.
One method of cleaning is dry ice blasting. This is similar to sandblasting, but much gentler. Dry ice pellets are used as the blasting medium.
The pellets are accelerated to extremely high speed in the dry ice blasting unit with a jet of compressed air and blasted onto the object to be cleaned using a gun and nozzle.
Upon impact with the surface, mini-explosions occur which, in combination with the locally generated cold shock (-78.5°C), detach dirt particles from the substrate.
