nnnnfor Metal Packaging
nnnnGreen, Sustainable Packaging for Our World
nnnnThe need for more cost-effective, environmental compliance
nnnncontinues to grow rapidly, driving significant changes to the
nnnnmetal container manufacturing industry.
nnnnNordson Powder Coating Technology is an effective, cost-
nnnnefficient, environmentally friendly solution for aluminum
nnnntube and aerosol monobloc manufacturers who face
nnnnincreasing requirements for reduced solvent emissions.
nnnnUsing the Nordson Inside-Spray Powder Coating System* to
nnnnapply durable, approved powder coatings to aluminum tube
nnnnand one-piece aerosol containers has significant advantages:
nnnn■ No major modifications required - applies powder to
nnnnthe container in the existing production line, reducing
nnnninstallation and new technology costs.
nnnn■ Eliminates solventborne VOC emissions from the
nnnncoating process.
nnnn■ Optimizes product performance and quality.
nnnn■ Eliminates incinerator costs for internal coating.
nnnn■ Eliminates paint disposal costs for internal coating.
nnnnSystem Operation
nnnnNordson Sure Coat* powder spray guns are positioned at the
nnnnspray machine in a manner similar to conventional liquid spray
nnnnguns. The after-filter, required to meet European CE and ATEX
nnnnsafety requirements, connects to the exhaust hood to reclaim
nnnnand recycle powder overspray.

nnnnCans are conveyed to the spray station where powder material is
nnnnapplied with Nordson lancing guns. Virgin powder is first sieved
nnnnin an ultrasonic vibratory sieve. Then, delivered through the
nnnnNordson HDLV® (High-Density powder, Low-Volume air)
nnnnpowder pump from the main hopper to the guns' feed hopper
nnnnwhich is equipped with high and low level sensors.
nnnnThroughout the coating application, powder from the gun, as
nnnnwell as overspray, is circulated back to the sieve using proprietary
nnnnNordson technology for maximum transfer efficiency.
