For plastics manufacturers producing small and micro sized products, those working with highly expensive additives, and in other applications where high precision dosing of small quantities of additives is required, a question has been raised: is it possible to obtain greater accuracy and precision from a loss in weight gravimetric feeders.

The existing plastic manufacturing process of weighing, blending and conveying, which plastic manufacturers have accepted as “standard practice”, is fraught with waste, inefficiency and unnecessary complexity.

Masterbatch is produced via a highly specialized compounding process: The ratio of pigment and additive must not only be accurate on a consistent basis for each batch, but they must be homogeneously mixed with the base polymer.
