Metering and dispensing technologies has introduced a range of precision fluid control systems such as pneumatically operated air pulse dispensers, and allied accessories like tips barrels, precision dispense valves [for various applications], pressure tanks, etc, to provide a positive control to handle variety of fluids. Dotting, lining, potting, filling, doming, encapsulating, spraying, coating, etc. Can be carried out with ease, efficiency and high degree of repeatability and accuracy. These systems are able to handle any type of fluid such as adhesives, anaerobics, light curing, uv curing, moisture curing [cyanoacrylates], latex based, solvent based, etc, coating fluids [hard coating of optical lenses], lacquers, dyes, etc.
