The basis of extrusion line automation has been gravimetric extruder control for over 35 years.

The principle of "Loss-in-Weight" guarantees a throughput determination accurate to the percentage, independent of the bulk density. Especially for co-extrusion lines, no other control principle for layer thickness control is conceivable.

The modular design of PLAST-CONTROL makes it possible to connect up to six gravimetric feeders per extruder. The recipe-accurate metering of expensive additives and masterbatches takes place directly above the extruder feed. Segregation is thus impossible.

All feeders are of course controlled synchronously with the extruders to ensure correct mixing at all times.
