Northwest Ohio is home to one of the world’s leading manufacturers of automotive glass, supplying brand name manufacturers like Kenworth, Peterbilt and DAF. When you supply glass to these renowned names, your finished product must be clearly flawless – like the glass itself. So, when it came time to improve the glass manufacturing process, this glass manufacturer turned to Nordson Corporation, a leader in the production of application equipment for liquid painting.

The Nordson team demonstrated how an Iso-Flo® manual electrostatic hand gun system could provide a precision spraying solution that would improve efficiency for the customer. Nordson conducted initial testing, then left them with a demo system to continue testing in their actual production environment. The Iso-Flo unit is a voltage block system that offers an easier, safer and cost-effective way to spray electrostatically charged waterborne coatings. The system supplies charged coating to the spray devices, while preventing the charge from conducting back through the paint-supply system. For single-gun manual operations, the Iso-Flo system includes a single paint reservoir. The reservoir fills from the grounded paint supply when the gun is triggered off between parts. When the gun is triggered on, the reservoir immediately disconnects from the grounded paint supply and connects to the spray gun. The electrostatic charge is applied within the Iso-Flo HD unit, between the paint reservoir and the spray gun.

The Nordson Iso-Flo® HD Voltage Block System features an advanced design which eliminates ground loops, eliminates potential for arcing or sparking, and provides higher charge density than traditional systems. It reduces downtime due to grounding problems associated with waterborne coatings, increases productivity by providing reliable performance and consistent high quality finish. Installation is easy with minimal maintenance , making the system an ideal choice for optimizing waterborne paint applications.

Rugged construction for the most demanding finishing operations
High-capacity, field-repairable pumps provide long life with minimal maintenance
Innovative arc-suppression feature that allows continuous coating without delay between cycles
Includes paint reservoirs sized for productivity and paint savings
Factory Mutual and CE approved

Our customer realized the benefits of using electrostatic spraying to apply the mold release agent. They now use the Nordson system three shifts per day, accommodating production to meet all its customer demands and providing many additional benefits.“The Nordson electrostatic spraying system is much more lenient and forgiving than the customer’s previous non-electrostatic spray system,” says Syrowski. “The mold release agent (supplied by Franklynn USA, Glenview, Illinois) is applied very accurately. Our customer has essentially eliminated overspray and material waste. In addition, by minimizing the sticking issues, product reject rate is now very low.” As a result, the system resulted in a fast return on investment. “The customer now sees 40 percent less mold release agent than with the old system,” explains Syrowski. “Material savings alone would have given a system payback in 12 to 14 months. When adding in the savings from fewer product rejects, the customer saw a system payback in less than six months.”

The Nordson Trilogy ® electrostatic spray systems are available in manual or automatic gun models that incorporate the latest in engineering and design materials. As a result, you’ll achieve many benefits that decrease the cost of ownership and enhance your bottom line.

Trilogy guns are the highest kV guns available in the industry today. At 93 kV, they provide superior transfer efficiency and paint wrap. With the strongest electrostatic load lines, voltage remains consistently high, even as gun-to-part distances change – ensuring high efficiency coverage. In addition, Automatic Current Limiting lets you customize the charge to coat specific part profiles, improving coverage across the part and into contours and recesses.

Wide range of air caps and fluid tips for consistent and repeatable atomization.
The highest kV in the industry – 93 kV – reduces material waste costs.
Handle forward design provides better balance and improved operator comfort.
Quick-flush fluid passages for ease of cleaning and maintenance.
Rugged gun bodies minimize maintenance costs and downtime.
More than 50 fluid tip and air cap combinations for even greater flexibility.
Automatic current limiting allows for greater control of charging which translates to better part coverage whatever the part profile
FM and CE approvals for electrostatic safety.
