GRAVIMETRIC DOSING UNIT

DG SERIES

 

Gravimetric dosing unit - dg series

The volumetric dosing units of the DM series have been designed to automatically and accurately dose master, additives and regrind. The synergy between design, applied technology and material quality results in high flexibility. They can be installed on injection moulding machines, blow-moulding machines, and extruders.

Two versions available:
• base version with manual loading of material.
• advanced version with automatic loading of material by means of a Venturi feeder.

Technical Specifications

• Inclined-axis feeder.
• Brushless motor.
• Remote 4’’ color touchscreen operator panel.
• Load cells.
• Lower slide gate to discharge material.
• Central flanged base to install up to 2 units.
• Complete with static mixer.
• ModBus interface.
• ETHERNET connector.
• USB connection.
• Connection to PC.

ACCESSORIES

    • Mixer.
    • Venturi feeder.
