Gravibelt with Smart Controller

Gravibelt

Is a gravimetric belt feeder. The unit accurately feeds free flowing color and additives at the throat of extrusion, blow molding
and injection molding machines. The system incorporates a special algorithm that filters out vibrations and movement from
mold clamping making it suitable for use on injection molding machines. The Gravibelt offers a wide dynamic feed range under
one setup. With a feed rate from 1 oz to 80 lbs/hr for pellets, and 0.5 oz to 30 lbs/hr for micro pellets. Isolated 10/100 Ethernet
makes possible the retrieval of production information. An integrated venturi loader is included with the system.

Features:
Easy Setup
  • Just enter the shot size and the % of additive you want to add. Start the feeder and it will automatically adjust itself to the machine cycle.Injection molding –
  • Enter the max output of your production machine and the % of additive you want to add. The feeder will automatically follow your extruder speed adjusting accordingly.
  • Extrusion Easiest startup in the industry! Just let the built-in hopper loader fill the hopper, start the feeder and you are producing within minutes.
