New Porcelain Enamel (PE) Coating Technologies Improve Operating Efficiency and Coating Performance


  • Encore® PE Guns incorporate 100 kV voltage multiplier for superior first-pass transfer efficiency
  • Encore PE Pump delivers up to 30 percent more powder than previous generation technology

AMHERST, OH, April 8, 2013 – Nordson Corporation (NASDAQ-NDSN), a recognized leader in liquid and powder coating technologies, introduces new Encore Porcelain Enamel (PE) Guns and Encore PE Pump to improve operating efficiency in porcelain enamel coating operations.  

“These technologies incorporate the proven industry-leading designs and application performance of their predecessors – the Versa-Spray® PE guns and the Nordson 100 Plus PE pump,” explains Bob Allsop, marketing manager, Nordson Powder Coating Systems. “However, with many design enhancements, our new products for PE coating incorporate features that enhance system versatility, efficiency and coating performance.”

Encore PE Guns are available in manual and automatic configurations.  Both feature a 100 kV voltage multiplier, assuring maximum first-pass transfer efficiency. For the Encore PE manual gun, this is a significant increase compared to previous-generation guns.

In addition, a new, positively retained deflector and locking pattern adjustment sleeve ensures consistent, repeatable spray performance. The addition of electrode air wash in the Encore design helps keep the gun charging electrode clean. This maintains maximum electrostatic charging efficiency. It also helps prevent agglomerated powder from disturbing the spray pattern or dislodging and inadvertently being applied to the part, causing possible surface finish defects.

Other enhanced gun features include:

  • An adjustable mounting bracket enables automatic gun positioning from 90-degrees up (from parallel to gun bar) to 90-degrees down, to efficiently coat the tops and bottoms of parts.
  • Parts commonality between automatic and manual guns to ensure consistency and minimize replacement parts inventory.
  • Optional straight and angled flat-spray nozzles and ion collector to meet various application needs.
  • A choice of gun controllers, both with digital, closed-loop pneumatic control – providing basic to more advanced operation.

The new Encore PE Pump delivers up to 30 percent more powder at comparable compressed air settings (or comparable output at significantly reduced settings) compared to its predecessor, the Nordson 100 Plus PE pump, In typical high-gun-count porcelain-enamel powder coating operations, this improved efficiency translates to substantial savings in compressed air consumption.

Both the Encore guns and Encore pump incorporate specially engineered parts designed for porcelain-enamel powder to maximize spray performance and wear life.  They are easy to disassemble for routine cleaning and maintenance and are also completely field repairable.
