Increases Dispensing Speed, Throughput, Precision, and Accuracy
East Providence, RI USA – March 5, 2014 -- Nordson EFD, a Nordson company (NASDAQ: NDSN), the world’s leading precision fluid dispensing systems manufacturer, introduces the new ValveMate™ 9000, state-of-the-art precision valve controller. The intricate microprocessor circuitry ensures the dispensing of precise, accurate, and repeatable amounts of the adhesives, lubricants, and other assembly fluids used in many of today’s advanced products, such as medical devices, automotive components, and portable electronics. The ValveMate 9000 incorporates advanced features such as Auto-Increment mode that adjusts dispensing parameters after a certain number of shots or a specific elapsed time.
The ValveMate 9000 offers independent dual-valve control programming, each with 24 watt temperature controllers for J-type thermocouples. Each channel can drive a remote high-speed solenoid valve up to 500Hz. At such fast dispense speeds, the high voltage can potentially damage the dispense system, so the ValveMate 9000 incorporates a clever solution with a unique spike-and-hold functionality. When properly set, the spike-and-hold function allows the controller to spike the voltage for a user-specified spike time and then throttle the voltage down to a user-specified hold voltage after the spike time expires.
In addition, two electronic pressure regulators (EPRs) provide stability in the fluid reservoir by maintaining consistent dispensing with full-to-empty pressure control. This allows the system to compensate for periodically changing conditions, such as fluid viscosity changes, and can be used to alter the dispensing patterns and create deposits of different sizes.
Unlike existing controllers, the ValveMate 9000 offers the ability to remotely program the set-up parameters of the dispense station from the host PC or programmable logic controller (PLC). This feature enables adjustments to be made quickly and easily on-the-fly, without stopping the production line.
“Valve controllers offer an extremely accurate and cost-effective way to regulate the dispensing cycle and keep assembly lines running at maximum efficiency, without the need for time-consuming programming or mechanical adjustments that require the production line to be shut down,” said Claude Bergeron, EFD global product line manager. “The benefits of controlled fluid dispensing include higher yields, greater process control, better quality, less rework, fewer rejects, and lower production costs.”
Nordson EFD designs and manufactures precision fluid dispensing systems for benchtop assembly processes and automated assembly lines. By enabling manufacturers to apply the same amount of adhesive, lubricant or other assembly fluid to every part, every time, EFD dispensing systems are helping companies in a wide variety of industries increase throughput, improve quality, and lower their production costs. Other fluid management capabilities include high-quality syringe barrels and cartridges for packaging one- and two-component materials, along with a wide variety of fittings, couplers and connectors for controlling fluid flow in medical, biopharmaceutical and industrial environments. The company is also a leading formulator of specialty solder pastes for dispensing and printing applications in the electronics industry.
