MGF-ST
10 REASONS TO CHOOSE THE MGF
01
3 STANDARD MODES
OF OPERATION
Cyclical, continuous,
extrusion following.
extrusion following.
02
REDUCES INPUT ERROR
The easiest setup procedure in the industry: feeder automatically adjusts to screw recovery time and extruder output.
03
FINE METERING RESOLUTION
100 rpm Stepper Motor advances at 200 increments per revolution achieving fine metering resolution of ± 0.2%.
04
AUTOMATIC RE‑CALIBRATION ENSURES CONTINUOUS ACCURACY
Automatic adjustments guarantee that feed rate is held to within ± 0.2% of desired let‑down ratio.
05
EASY‑TO‑USE MICROPROCESSOR CONTROLLER SAVES TIME
User‑friendly controller has intuitive setup procedure.
06
DETAILED MATERIAL USAGE DOCUMENTATION
Microprocessor control allows data collection via G2 networking software, or MLAN protocol via Ethernet.
07
ELIMINATES DOWNTIME ASSOCIATED WITH COLOR CHANGE
Feeder automatically re-calibrates to new color, so no additional setup required. Spare hoppers are available for faster color changes.
08
NO TOOLS REQUIRED
Load cell assembly slips easily into place. The metering device is locked in place by two clips and can be quickly removed.
09
DUAL LOAD CELLS
Hopper is mounted on two load cells to prevent distorted readings from cantilevered loads in the hopper.
10
FAST CLEAN‑OUT AND REPLACEMENT
Aluminium hopper with brushed exterior holds up to 25 lb (11 kg) of material. Easy removal and replacement of supply hopper allows fast material change. Spare supply hoppers and hopper extensions are available.
TECHNICAL SPECIFICATIONS
MGF CONFIGURATION - ST VS. STV
The standard MGF‑X‑ST stepper configuration can be used for either injection or extrusion applications. The injection mode utilizes a contact closure from the machine as a means of detecting the plastification time while the extrusion mode input will accept a 0‑10 Vdc proportional signal from the extruder drive. MGF‑X‑STV is the alternate option. The input circuitry is voltage sensing. The V suffix represents voltage and is a different circuit board which does not have extrusion following capability. This model is injection only.
