Nordson EFD Launches Innovative P-Jet Non-Contact Jetting Technology for Higher Throughput Yields

The launch of the P-Jet and P-Dot comes with EFD’s recent acquisition of Liquidyn, a Germany-based company that designs and manufactures non-contact micro dispensing valves. The company was founded in 2006 by two German engineers looking to provide manufacturers more efficient fluid dispensing options.

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.”
