Plastore®

The GRAVIBELT is a single gravimetric beltfeeder.  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

• Injection molding -  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.
• Extrusion - Enter the max output of your production machine and the % of additive you want to add. The feeder will automatically follow your extruder speed and adjust accordingly.

Easiest startup in the industry

• Just let the built-in hopper loader fill the hopper, start the feeder and you are producing within 2 minutes.
