Screw dosing unit MGF

gravimetricloss-in-weightfor the plastics industry

This compact loss-in-weight additive feeder precisely measures the amount of additive that is fed directly into the machine throat to eliminate costly waste. Simple, accurate, affordable. The MGF proven loss-in-weight technology automatically calibrates itself, eliminating manual catch-and-weigh calibration procedures and even more common and erroneous guessing of metering rates. 4 standard modes of operation Cyclical, continuous, extrusion following and rate (rate kg/h). Reduces input error The easiest setup procedure in the industry: enter let-down ratio and either shot weight or lb/hr output and press start. Feeder automatically adjusts to screw recovery time and extruder output. Fine metering resolution 100 rpm Stepper Motor advances at 200 increments per revolution. In combination with digital control, the 200-step rotation achieves fine metering resolution of ± 0.2%. Automatic re-calibration ensures continuous accuracy Automatic adjustments guarantee that feed rate is held to within ± 0.2% of desired let-down ratio. East-to-use microprocessor controller saves time User-friendly controller has intuitive setup procedure. Detailed material usage documentation Microprocessor control allows data collection via G2 networking software, or MLAN protocol via Ethernet. Eliminates downtime associated with colour change Feeder automatically re-calibrates to new colour, so no additional setup required. Spare hoppers available for faster colour changes.
