Marse MVDU VS – Volumetric doser

The Marse MVDU VS range is a brushless-motor volumetric doser with a stainless-steel screw that accurately doses masterbatch or additive into the main material – for injection moulding and extruder machines alike. The microprocessor control automatically regulates screw speed and dosing cycle. All material-contact components are made entirely from stainless steel.
