Miniature dosing systems for precision dispensing

PreeFlow volumetric micro dispensers can accurately dispense oils, greases, sealants, adhesives, silicones, fluxes, solder pastes, foodstuffs (FDA approved) or abrasive media.

The accuracy of the volume dosed is unaffected by temperature, pressure or viscosity.

Dosing fluid pressures of 16 to 20 bar can be achieved.

All PreeFlow volumetric micro dispensers and volumetric dosing systems have an instant reverse-flow feature for a clean, controlled material separation with no dripping or stringing.

They use a volumetric micro-dispenser system utilising the Endless Piston Principle that enables the dosing of a multitude of different media with just one efficient volumetric micro-dispenser unit.

A popular exhibition piece is to show the dispensing of raw egg yolks and on occasions, live goldfish without harming either.

With volumetric dosing accuracies of one per cent and repeatability of greater than 99 per cent, product wastage is reduced.

Typical applications for PreeFlow volumetric micro dispensers include: SMT system applications; micro-potting applications; glob-topping of delicate IC devices; precision-oiling and greasing of bearings and small assemblies; precision adhesive bonding of small assemblies; gasket dispensing; precision bonding applications; packaging application using UV-cured adhesives; photovoltaic component manufacture; optical drive manufacture; LED and LCD manufacture; medical device manufacture; and cake decoration.
