Unsurpassed coating quality with the greatest possible flexibility and economy:
This is what your customers expect. Nordson's fully automated powder coating systems combine dense-phase technology with intelligent robots specifically developed for coating processes.
Consistently economical
Powder coating systems attain the highest levels of productivity and the best possible, operator-independent, endless repeatable coating quality - along with huge savings in powder, energy and manual interventions - when combined with robots and an integrated control system.
Incorporated into other highly automated and integrated production processes such as Nordson's high-end solutions for conveying and powder recovery, robot-operated guns help reduce powder consumption by up to 45 % while maximizing flexibility and profitability of production at the same time.
Dense-phase technology and robotics
The heart of highly efficient dense-phase technology is the HDLV® pump which pumps a large quantity of powder and very little air to the Encore® HD gun, forming a "soft powder cloud" that contacts the workpiece at low velocity. As a result, the discharge nozzle of the gun can approach the workpiece much, much closer than with other methods. This is exactly what robots do best - unlike hydraulically or pneumatically operated devices, and also with greater speed, precision and endurance than a human hand.
An unbeatable combination
Using a workpiece recognition system (Part Identification Information), the robot also "recognizes" the object, confirms that it is correctly positioned on the conveyor belt and tells the control system and the powder center the appropriate electrostatic, air and powder settings to make.
It follows the contours of the part and aims precisely at hard-to-reach areas, thereby optimizing the coating of surfaces, edges, corners and cavities with unsurpassed efficiency - and it does so always with equal perfection, endlessly repeating without the slightest deviation, absolutely free of human factors or error.
Consistent use of suitable robots in this way makes it possible to increase the quality and cost benefits associated with dense phase technology's 100 % process control even further.
Such sophisticated powder coating systems are already equipped to handle the future needs of modern smart factory production.
The benefits of fully automated robotic powder coating
Nordson's industry-leading HDLV® pumps and Encore® HD spray systems deliver an unmatched level of productivity and coating performance in robot applications.
- High output stability over time due to no wear parts inside the pump affecting output
- Unmatched productivity with up to 700 g/min powder output
- Soft spray with minimum air for up-close application even at high output
- Superior coverage of complex shapes with low spray velocity.
