Fast and high precision jet dispensing

With the growing demands of miniaturization and cycle time reduction, the jetting offers faster speed, high precision and more flexibility in terms of accessibility and trajectories. 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.

Jet dispenser

– High frequency dispensing of low volume droplets with low and high viscosity products
– Advantageous cycle time as no vertical motion is needed
– Capacity to dispense into tight spaces with all shape trajectories
– No contact to the working surface and no needle – low maintenance
– Simple setting of the dispensing parameters via numerical controllersuch as drop size, pulse time, etc.
– Heating of the valve seat to ensure high degree of repeatability of the drop volume
