Gravimetric Doser SGD

    The servo-driven SGD series gravimetric doser is controlled by PLC. It is suitable for injection moulding and extrusion occasions, which require a precision dosing ratio with masterbatch, additive, virgin, or regrind. SGD can work with the VL - Venturi Loader to realize the auto conveying of the masterbatch to the dosing unit. The unit is also available in dual doser.
