Jet Dispensing

Where dispense shot sizes are becoming smaller, and/ or when your products do not allow physical contact with a dispensing needle, jetting is the most feasible solution.

Adhesives, greases, oils, fixing agents and many other liquids are applied with maximum speed and accuracy through a piezo-driven dispensing valve that is designed for extreme durability and low cost of ownership. The valve is electrically actuated. The material may need to be pressurised at between 0.1 Bar and 100 Bar.

Jet Dispensing Benefits

  • High durability, low maintenance costs
  • No rejects due to collisions between substrate and dispensing needle
  • Highest process reliability
  • Process acceleration due to a maximum dispensing speed
  • Lowest change-over-times, appropriate for various liquids
  • Highly accurate dispensing position
  • Extreme fluid efficiency
  • SPC-compatible control systems offer maximum process control

Applications of Jet Dispensing

Jet Dispensing can be applied in almost every industry. Examples of Jet Dispensing applications are: 

dispensing oils and greases for micromechanical and electronic components, cooling lubricants, spraying solvents and primers, cleaning and disinfection agents, dispensing food colors and flavors, hotmelt adhesives, sealing lacquers, silicone oils and materials for pressure sensitive adhesive tapes.

In traditional contact methods, a needle touches down and physically applies the fluid. With non-contact dispensing, a jet hovers over and shoots fluid at the work surface without ever touching it.

In jet dispensing, the fluid is separated from the applicator using droplet momentum which results in a perfectly round dot.

Jetting produces dots with an extremely small size, a low volume and high consistency. Furthermore, jet dispensing has positive shut-off which enables it to execute precise lines and sharp corners.

Dispensing results can be perfected by fine-tuning the jet and fluid pressures, drop size, drop rate, and dispensing parameters such as refill and dwell time.

Jet technology is perhaps best defined by what does not happen during jetting – there is no contact with the work surface.
