Volumetric gravimetric and liquid Series

The ‘DUV’ volumetric, ‘DUG’ gravimetric and ‘DUL’ liquid feeder series are designed for the optimal and efficient automatic dosing of masters, additives, regrind granules and liquids. The machine series presents a synergy between design and applied technology, which makes for high flexibility for different dosing requirements of injection moulding machines, blow moulding machines and extruders.

Dosing screw

The range features a wide variety of screws (different diameters) made of stainless steel and able to provide optimal dosing thanks to their patented profile. The dosing screw, with its inclined axis, offers maximum performance in terms of precision and stability.
