Jet Pressure

 

3.6

Jet pressure is the force that pushes the fluid out of the jet when it is dispensed. Too 
little jet pressure and the fluid will not leave the nozzle completely and material will 
accumulate on the nozzle. Too much jet pressure and the fluid will have satellites or 
splatter when it hits the surface of the product. Jet pressure must be between 35-65 psi 
to work correctly. 

1.

 

Set jet pressure at 45 psi to start. 

2.

 

Dispense the material and examine the nozzle and surface that was dispensed 
on for buildup, splatter, or satellites. 

3 .

 

Adjust the jet pressure until the results are correct.   

Do not set jet pressure higher than 65 psi. 

 

Jet Shutdown Procedure

 

3.7

1.

 

Decrease system pressure to 0 psi. 

2.

 

Shut off the heater and wait approximately five minutes for the heater block to 
cool. 

3.

 

Turn the air cap counterclockwise to remove it. 

4.

 

Turn the thumb screw counterclockwise to loosen the syringe.
