Dosage / Volumetric

Filling and dosing machines are packing equipments which measure out a product from a bulk supply by some predetermined value, e.g. volume, level in a container, mass or count. The filling way used is influenced largely by the nature of the product e.g. liquid, gas, piece goods, powder, free flowing solids or sticky paste, but also by the measure for selling the product e.g. by weight, by volume or by count.

Volumetric and level filling is typically associated with liquid or gas products, but a whole range of products also use this technology including dry products such as powders and granules, dog foods, cat foods, through to semi-liquids such as gels and pastes, or even products which are normally solid at room temperature like fats, lipstick and stick deodorants.

Different methods of filling have been developed not only to accommodate the different characteristics of the product but also to achieve various accuracies of fill, because while for a low value product there may be no incentive to fill more accurately than the statutory requirements, for high value product increased accuracy can represent a considerable saving in product “give-away”.
