PRO-GRAV

All of our automation principles over the last 35 years have been based on gravimetric extrusion control.

The “loss in weight” principle guarantees precise measurement of throughput and control designed for all types of extrusion processes. Extrusion control has proven to be an essential first step for establishing a stable extrusion process.

Fully modular construction allows up to 6 dosing units plus main material to be fitted to each extruder (including co-extruders). Precise dosing of costly additives and master batches takes place directly above the extruder throat.

All dosing units outputs are synchronized with the main hopper output to guarantee an accurate product recipe. The latest generation of dosing unit now incorporates a high torque motor delivering a wide speed range.

 

Advantages:

  • Independent from bulk density
  • Fast product change
  • Rigid construction
  • Precise dosing of small volume
  • Easy operation and simple target entry
  • Customer tailored solutions
  • Up to 7 components per extruder
  • Minimal dosing screw changes necessary
  • Easy cleaning due to removable hoppers
