Powder Coating System Green, Sustainable Packaging for Our World The need for more cost-effective, environmental compliance continues to grow rapidly, driving significant changes to the metal container manufacturing industry. Nordson Powder Coating Technology is an effective, cost- efficient, environmentally friendly solution for aluminum tube and aerosol monobloc manufacturers who face increasing requirements for reduced solvent emissions. Using the Nordson Inside-Spray Powder Coating System* to apply durable, approved powder coatings to aluminum tube and one-piece aerosol containers has significant advantages: ■ No major modifications required - applies powder to the container in the existing production line, reducing installation and new technology costs. ■ Eliminates solventborne VOC emissions from the coating process. ■ Optimizes product performance and quality. ■ Eliminates incinerator costs for internal coating. ■ Eliminates paint disposal costs for internal coating. System Operation Nordson Sure Coat* powder spray guns are positioned at the spray machine in a manner similar to conventional liquid spray guns. The after-filter, required to meet European CE and ATEX safety requirements, connects to the exhaust hood to reclaim and recycle powder overspray. ^Patent Pending Cans are conveyed to the spray station where powder material is applied with Nordson lancing guns. Virgin powder is first sieved in an ultrasonic vibratory sieve. Then, delivered through the Nordson HDLV® (High-Density powder, Low-Volume air) powder pump from the main hopper to the guns' feed hopper which is equipped with high and low level sensors. Throughout the coating application, powder from the gun, as well as overspray, is circulated back to the sieve using proprietary Nordson technology for maximum transfer efficiency.

Powder Coating System for Metal Packaging Precise Coating Control Powder particles receive an electrostatic charge as they exit the spray gun. As a result, they are attracted to the grounded container. Setting kV output provides maximum transfer Nordson Automatic Feedback Current (AFC) lets the operator set maximum current (uA) output from the spray gun to prevent excess charging of sprayed powder. Setting is adjustable in 1 kV increments at the range of 25 to 95 kV. This provides an optimum combination of kV and electrostatic field strength for coating parts with interior corners and deep recesses...

Powder Coating System for Metal Packaging Guns and Power Supply The aerodynamic shape and smooth engineered-material external surfaces of the Sure Coat* automatic gun, facilitate fast, easy powder cleaning and maintenance. All connections for powder tubing and power cable for the integral voltage multiplier feature a quick-disconnect design. The gun is easily disassembled for routine maintenance to check for wear on all powder-contact parts. And the integral voltage SURE COAT- <£*$> Spray nozzle extensions can be customized by Nordson to accommodate varying container lengths and diameters. Simple,...
