The advantages brought by the integrationof DIE-CLAR (an innovative system for thecleaning of dies used in aluminium extrusionindustry) and CRYSTALFIX (the most updatedtechnology for the recovery of caustic sodaused in the process of dies pickling) havebeen successfully proven by Italtecno on thefield.

With an INTEGRATED DIE-CLAR & CRYSTAL-FIX SYSTEM all the advantages connected toeach individual technology are summed to-gether and provide a total answer to theproblems caused by the conventional diespickling systems:

• Fully automatic operations, from diescleaning sequence to spent caustic sodarecovery

• 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 detachmentpre-treatment.
