Gravimetric dosing unit GD1

loss-in-weightfor injection molding machinesautomatic

for micro injection moulding, injection moulding and extrusion Loss-in-weight metering for 2 additives • For shot weights from 10 to 500 g • Precision dosing drum technology • No scrapers • Stepper motor with encoder The unique drum dosing concept was developed especially for dosing free flowing materials. The special geometry of the exchangeable dosing drums and the speed adaptation allows precise metering of smallest quantities down to 0.1 g*1 per shot. Thanks to its high precision and repeat accuracy, the drum dosing system is ideally suited for shot dosing for injection moulding and micro injection moulding as well as continuous dosing on extruders. The use of different drum geometries allows a large dosing range from about 10 g/h to >300 kg/h*1. Through the well thought out design, calibration and cleaning are quick and easy. BENEFITS • Up to 2 components can be metered • Gravimetric loss-in-weight metering • Automatic adaptation to material bulk density • Gravimetric consumption measurement • No wear parts (scrapers) • Rapid emptying of batch/additive station for fast colour change and material savings • Largely resistant to vibration and impacts • Easy cleaning without tools • Large dosing range through variable speed and drum geometries • Continuous discharge – low pulsation
