German automation supplier Bruckmann Steuerungstechnik GmbH has developed an additional software module for direct extrusion lines.
BSG said the software is designed for twin-screw co-extrusion lines used for film extrusion. That equipment usually uses conveyors and feeders in combination with two extruders. A double screen changer/melt pump assembly is installed downstream of the extruders, and both lines converge at a flat die.
BSG's software controls the complete extrusion line from one operator control panel, maintaining a consistent material throughput at the die, even during screen changing.
The software has been installed on a PET thermoforming line in Turkey.
BSG, a member of Kreyenborg Group, is based in Uedem, Germany.
