Jet dispenser

With the growing demands of miniaturization and cycle time reduction, the jet dispenser offers faster speed and high precision; but also more flexibility in terms of accessibility and trajectories. Furthermore, this contactless dispensing technique uses pneumatic or piezoelectric actuated valves to propel droplet of fluids out of the nozzle, which results in dots of small size and volume.

As there is no contact with the surface and no necessity of a needle, the fluid can be dispensed into tight spaces along any trajectory such as thin lines, sharp corners, etc. However the major asset of propelling small dots from above the working surface is that no Z-motion is required, thereby significantly increasing speed and reducing cycle time.

The jet dispenser can be integrated in most of our standard dispensing platforms including: MRC500, TR300, OEM, and station.

The main features of our jet dispenser head include:

  • High frequency dispensing of low volume droplets with low and high viscosity products
  • Ability to dispense into tight spaces with all shape trajectories
  • Simple setting of the dispensing parameters via numerical controller such as drop size, pulse time, etc.

3 reasons to choose the jet dispenser

  1. Significant cycle time advantages – no need of vertical motion.
  2. No contact to the working surface and no needle – low maintenance.
  3. Heating of the valve seat to ensure high degree of repeatability of the drop volume.

  • High precision dispensing of glue, lubricating oil and grease, point by point, multipoints or in line for watch movements and components as well as micro-mechanisms
