Is anyone aware of a good method of accurately but quickly dispensing small quantities (approximately a cc or less) of a very viscous
adhesive?
The adhesive manufacturer's system uses a time and pressure method. This has a pressure pot of adhesive and a dispensing valve which is held open for a particular period of time (a few hundred milliseconds). Pressure and time can be adjusted to vary the amount dispensed.
We have looked at various positive displacement dispensing systems (piston pump, peristaltic pump), but we have not been able to find one which is suitable for a very viscous fluid. Is anyone aware of a comercial system
which is suitable for this application?

I have used the IVEK pumps for adhesives and they work fine.

We use Ivek dispensers for activator, but not for adhesive. The activator is relatively thin, but the adhesive is apparently much too thick for this hardware.

EFD uses a time/pressure method for dispensing liquids and is some of the best equipment available for doing it that way. Steve Hyatt Parker Hannifin RAC Division [email protected]
