High-pressure water jetting at pressures of up to 3000 bar (45,500 psi) is becoming increasingly widespread as a method of activating the cylinder bore surfaces of engine blocks prior to thermal coating. Now, however, Dürr Ecoclean’s PulseBoreCenter permits the use of no more than 600 bar (8,702 psi) in this application—up to an 80% reduction.The gain is due to the integrated EcoCBooster used in the PulseBoreCenter, which generates a pulsating water jet of much higher kinetic energy. Users will thus benefit from substantial savings in investment and operating cost as well as from improved process results. This technology offers advantages also in other operations such as cleaning, deburring and decoating.
