Time-Pressure Dispensing
Tutorial
Time-Pressure Dispensing
Time pressure dispensing is the most common dispensing
method used today. Its popularity stems from the need for
process control and the fact that it is possible to dispense
from disposable containers without the need for cleaning.
Our time-pressure dispensers deliver a measured amount of
air pressure, for a measured amount of time, to a pre-filled sy-
ringe barrel. This controlled shot of air pressure forces mate-
rial out of the delivery end of the barrel, through a dispensing
tip and out to the application surface.

Basic Dispensing Guidelines
• Small Shot Size = small dispensing tip,
low fluid pressure, short dispense time
• Large Shot Size = larger dispensing
tip, higher fluid pressure, longer dis-
pense time
• Low Viscosity Fluid = small dis-
pensing tip, low pressure, time
as required
• High Viscosity Fluid = larger dis-
pensing tip (tapered dispensing tip
recommended), high pressure, time
as required
• Positionsyringebarrelat45°angle
• Positionthedispensingtipclosetothe
work surface then activate the dispense
cycle and keep the syringe barrel in the
same position until the cycle is completed
• Ifvacuum“suck-back”isneeded,useonly
enough vacuum to draw back fluid into
the dispense tip. Excessive vacuum could
draw air into the fluid and also could draw
fluid into the dispenser.
Factors Affecting Dispensing
• Pressure: Increas-
ing fluid pressure will
increase dot size and
vice versa
• Time: Increasing
dispense time will
increase dot size
and vice versa
• Dispensing Tip Size:
Larger inside diameter
(orifice) needle results
in bigger dot size
