The powder coating system installed at Blue Willow Aluminium is ACT Nordson’s most advanced system available globally and comprises;

  • The Nordson ColorMax booth for fast and secure colour change.
  • Nordson Encore HD Application equipment with improved transfer efficiency.
  • Nordson Spectrum HD Powder feed center with Nordson Powder Pilot Control System.

ColorMax Booth
The Nordson ColorMax Booth is a highly efficient booth which lends itself to fast and secure colour changes resulting in minimal down time. It is constructed using proprietary canopy material, which has the least amount of powder attraction of any material on the market today, to expedite color-change operations. The booth, by virtue of its design, is environment friendly in that it contains powder, recycles reusable powder, allows users to dispose of waste powder under controlled conditions and saves energy through fast colour change times and variable fan motor speeds.

Encore HD Application
The most revolutionary aspect of the new installation at BWA is the introduction of the Nordson Encore HD application which is based on the ground breaking dense phase gun and pump design as opposed to the old traditional venture technology. These Powder Spray Guns provide for the most versatile and efficient performance available today and allows easy adjustment of the powder concentration and spray velocity to achieve optimum coating coverage and cured finish quality for every conceivable part type therefore resulting in:

  • Consistent, repeatable applied coating thickness and uniformity
  • Highest transfer efficiency
  • Fastest powder deposition rate
  • Lowest operating cost per part
  • Improved coverage of interior corners and recessed areas
  • Automatic purge cleaning of gun, hose and pump
  • Contamination-free, ultra-fast color change
