The procedure of removing processing contamination from Moulding Tools, can lead to expensive tool repair costs. Past practices of using abrasive materials can now be effectively replaced by the use of Soft Impact Granulated Blast media's in a Pressure or Suction Blast Cabinet. Melamine and Urea are the most effective grades for this purpose, performing successful cleaning on hardened tool steel and also aluminium tools without damage. The additional cost of Plastic Media is more than justified when significant savings on tool repairs are taken into consideration. Heat discolouration in tools remain when using Plastic Media, proving that no surface metal is removed, thus reducing tool wear / maintenance. Benefits using Plastic Media include;  Tool Refurbishment - Cost Savings.  Reduced scrap from start up lifts.  No use of chemicals.  Dry blasting, no oxidisation.  Thermoset media can clean hot tools, meaning less down time.  Can be used in all Dryblast equipment
