The cleaning of production moulds is a classic application for the dry ice procedure.

The cleaning of moulds is regularly performed at differing intervals albeit the downtimes of a production mould is greatly dependent upon the quality of the cleaning. In order to ensure the dimensional stability of the products over a longer period of time, the cleaning procedure used must not change the mould surface. Exactly for this application the dry ice cleaning methods provides huge benefits because the dry ice Particles do not take of parts of the surface.  The coatings to be stripped off generally consist of release agents or product remains.

The use of dry ice during the cleaning of production moulds makes it possible to clean the moulds directly in the press. Laborious changes of moulds cease to apply and the production capacities can be increased. The relatively soft granulate does not damage the moulds. Dry ice does sublimate on contact which leads to the cleaning process having no residues other than the dirt itself. The temperature of dry ice (minus 78 degrees) ensures that the residues become brittle, and thus also the hardest impurities are removed. Furthermore, does the sublimation process clean any spring valves in the mould.

The dry ice blasting method is suitable, for instance, for casting moulds, tyre moulds, rubber moulded articles, moulds for PU foam products, moulds for plastic products, block foam moulds or even baking tins in the food industry.
