for Metal Packaging

nnnn

Green, Sustainable Packaging for Our World

nnnn

The need for more cost-effective, environmental compliance

nnnn

continues to grow rapidly, driving significant changes to the

nnnn

metal container manufacturing industry.

nnnn

Nordson Powder Coating Technology is an effective, cost-

nnnn

efficient, environmentally friendly solution for aluminum

nnnn

tube and aerosol monobloc manufacturers who face

nnnn

increasing requirements for reduced solvent emissions.

nnnn

Using the Nordson Inside-Spray Powder Coating System* to

nnnn

apply durable, approved powder coatings to aluminum tube

nnnn

and one-piece aerosol containers has significant advantages:

nnnn

■ No major modifications required - applies powder to

nnnn

the container in the existing production line, reducing

nnnn

installation and new technology costs.

nnnn

■ Eliminates solventborne VOC emissions from the

nnnn

coating process.

nnnn

■ Optimizes product performance and quality.

nnnn

■ Eliminates incinerator costs for internal coating.

nnnn

■ Eliminates paint disposal costs for internal coating.

nnnn

System Operation

nnnn

Nordson Sure Coat* powder spray guns are positioned at the

nnnn

spray machine in a manner similar to conventional liquid spray

nnnn

guns. The after-filter, required to meet European CE and ATEX

nnnn

safety requirements, connects to the exhaust hood to reclaim

nnnn

and recycle powder overspray.

nnnn

^Patent Pending

nnnn

Cans are conveyed to the spray station where powder material is

nnnn

applied with Nordson lancing guns. Virgin powder is first sieved

nnnn

in an ultrasonic vibratory sieve. Then, delivered through the

nnnn

Nordson HDLV® (High-Density powder, Low-Volume air)

nnnn

powder pump from the main hopper to the guns' feed hopper

nnnn

which is equipped with high and low level sensors.

nnnn

Throughout the coating application, powder from the gun, as

nnnn

well as overspray, is circulated back to the sieve using proprietary

nnnn

Nordson technology for maximum transfer efficiency.
