October 28, 2015 - Nordson EFD introduces pneumatic non-contact dispensing systems. The P-Jet and P-Dot valves and V100 controllers jet low- to high-viscosity fluids with great precision and repeatability. They are designed for use in many types of applications and multiple industries including automotive, electronics, aerospace, and medical.
Benefits of the P-Jet include dispensing frequencies of up to 280Hz with dispensable volume starting at 3 nL. Both the P-Jet and P-Dot feature exchangeable nozzles and dispensing tappets to adapt to different kinds of applications. Both are easy to use and maintain featuring wetted parts that are separate from the actuator. They require low voltage of 24 V and maximum fluid pressure of 87 psi (6 bar) to operate, which are important when evaluating safety considerations. In addition, the valves can be easily integrated into production lines.
Pneumatic non-contact dispensing technology benefits include:
- Time savings due to easier positioning of the part and high dispensing frequency and accuracy
- Reduced part damage and contamination due to there being no contact with the part
- Uniform fluid deposits independent of part topography and surface structure
- Easy, safe adjustment of dispensing volumes
- Process control
The P-Jet dispenses low- to medium-viscosity fluids such as solvents, oils, greases, silicones, paints, and fluxes in beads and lines. Common applications include filling, potting, sealing, and coating. The P-Dot dispenses higher viscosity fluids such as adhesives, lacquers, oils, greases, silicones, and fluxes in dots, beads, and lines. Attaching very small electronic components (SMD parts) onto printed circuit boards and substrates is a good application example. "The P-Jet and P-Dot non-contact jet valves offer manufacturers a fast, simple way to generate precise, repeatable micro-deposits for even the most demanding dispensing processes," said Peter Langer, Nordson EFD Business Unit Director - Valves.
"These valves are designed to last a long time with extremely low maintenance."
About Nordson EFD
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.
