The advantages brought by the integration of DIE-CLAR (an innovative system for the cleaning of dies used in aluminium extrusion industry) and CRYSTALFIX (the most updated technology for the recovery of caustic soda used in the process of dies pickling) have been successfully proven by Italtecno on the field. With an INTEGRATED DIE-CLAR & CRYSTAL- FIX SYSTEM all the advantages connected to each individual technology are summed to- gether and provide a total answer to the problems caused by the conventional dies pickling systems: • Fully automatic operations, from dies cleaning sequence to spent caustic soda recovery • Highly environmental friendly process • Total enhancement of safety for workers • Recovery of aluminium metal • Recovery of caustic soda • No spent toxic/hazardous waste to be di- sposed or to be treated This integrated approach to dies cleaning, can be additionally enhanced by implemen- ting a mechanical aluminium detachment pre-treatment.
