Accurate, consistent application of cyanoacrylate is very often a critical in production, due to low viscosity of the liquid. However, Nordson EFD claims its Ultimus II Dispensing Workstation solves this problem by dispensing the same amount of adhesive every time.
 It has been designed to eliminate rework and according to Nordson, cuts adhesive use an average of 50%.
The Ultimus II Workstation is said to eliminate variations in the amount of cyanoacrylate applied by using a precisely timed air pulse instead of guesswork to determine how much material is dispensed. For optimal control of thin fluids, the system has a 0-15 psi ( 0-1 bar) psi pressure regulator, and uses a microprocessor-based digital timer with four decimal places to control deposit size.
Other features include simultaneous digital display of all dispensing parameters, programmable in nine languages (including air pressure, shot count, dispense time and vacuum), and a 'Teach' function designed to simplify initial setup.
Cyanoacrylate is dispensed from a syringe reservoir that can be held like a pen or mounted on an optional arm to leave the operator's hands free to position or assemble parts.
To apply an identical amount of cyanoacrylate on each part, the user places the dispense tip in position and presses an electric foot pedal. Each Ultimus II Workstation includes a complete introductory supply of syringe barrels, pistons and dispense tips matched to the user's specific application.
