Gravimetric Masterbatch Control System
Gravimetric Masterbatch Control System
Controls weight-per-metre and masterbatch dosing as one system. The masterbatch unit follows the extruder dynamically under closed-loop control, holding the ratio to ±1%.
What hand-dosed masterbatch costs
Every product has a different formulation, and for years masterbatch has been dosed mainly by hand — inaccurate additions and uneven mixing, which leave pipe quality unstable and add labour cost and needless effort.
And because it rests on the operator's diligence, a moment's lapse can cost the company dearly.

Where it is used
Plastic film, cable, pipe, compounding and chemicals — and any industry that needs several components dosed to an exact ratio.
What the masterbatch control system is
The gravimetric masterbatch control system controls the weight per metre and, at the same time, automatically controls masterbatch dosing — the two functions combined into one control system.
