Mould cleaning in foundries
Cleaning moulds for Die Casting in aluminium and iron goes very well with dry ice blasting. Most foundries use the machines to clean moulds where they apply "die casting" to cast products in aluminium or Iron. In fact they remove almost weekly the silicone graphit release products. That product is sprayed to avoid that the aluminium or iron sticks to the metal moulds. After some days of production this anti-sticking layer is partly removed and have to be renewed. Before spraying a new anti-straying coating, they always remove the old and sticking layer.
