Common methods for precision dispense
of liquids include positive and air displacement methods.
A proprietary dispense
control system which accounts for variances in fluid dynamics through the dispense
cycle is at the heart of the system and its accuracy, according to Frederick.
This will not be an issue on a single unit but if multiple systems are made, the tubing tolerance on the ID may affect the dispense
Units come complete with supply containers, controls, meters, dispense
valve, housing and all interconnecting piping.
It operates on a 10.8-volt rechargeable lithium ion battery and can dispense
up to 60 cartridges before the charge is exhausted.
adjustable quantities of substance for virtually any application including oils for lubrication, liquid for food additives, inks, adhesives and chemicals.
The controller s unique microprocessor circuitry provides exact time control of the dispense
cycle with an improved user interface.
Six valve models (260, 460 and 960) dispense
or store up to six different ingredients.
And instead of central blending, individual dispensing systems can automatically blend and dispense
mold charges on demand at the press.
Accurately repeats shots of 1 cc and up at speeds from less than 1 lb/min to 100 lb/ min and dispenses
viscosities from water-thin to heavily filled pastes.
Its new Gravimold system automatically and precisely dispenses
up to four material components into a mold.
REQUIREMENTS FOR HIGHER speed and precision in applying very small volumes of material in precise locations have been met with the development of better pump technologies and dispense
methodologies for a much more controlled and automated process with tighter tolerance levels and higher throughput.
