Pokraskin The syringe dispense system is a very popular system and ideal for adhesives and sealants packaged in standard syringes. The principle is that a timed pulse of air is applied to the back of the syringe and this then forces the adhesive through the nozzle tip. The quantity dispensed is varied by the pressure applied, the nozzle diameter and the time of the air pulse [2]. Figure 8.8 shows a typical syringe dispenser.
An anti-drip feature is often incorporated using a vacuum to hold back the adhesive whilst the system is idle. Other features include digital pressure control and low-level monitoring of the fluid in the syringe.
