Hardware and software package for extrusion control
Gefran's new GF-Pack Extrusion is a packaged hardware and software system for the automation of individual small plastic extruders or large-scale extrusion lines. Each system is matched to the customer's requirements with preconfigured application software and a combination of standard Gefran automation elements that include the Digistar II industrial PC with choice of touch screen monitors, the Gilogik II PLC with remote digital and analogue I/O modules, and Geflex temperature controls, counters and relay modules for the distributed control of temperature zones.
The preloaded GF-Pack Extrusion application software includes an intuitive HMI with a graphical interface and straightforward parameter-based machine set-up for temperature zone regulation and motor control. The automation architecture is based upon high-speed GDNET deterministic networking from the Digistar II host to the Gilogik II PLC and with a Modbus RTU network for Geflex temperature control components.
GF-Pack Extrusion is available in a choice of three levels to cover PID control of temperature zones, current, pressure and alarm control with full synchronisation of extruder speed, batching and cutting processes.
Additional functions
The entry-level Extrulabo system is aimed at laboratory and small-scale extruders. For mid-range systems, the Extrucomp package includes increased batch and feed controls, additional filter, granule and centrifuge controls, plus auxiliary motors and water cutting. For sophisticated tubular and profile extrusion solutions, the Extrupipe builds on theses features with typical functions for complete large scale extrusion lines.
Each application package is completely integrated and scalable, with a number of standard and optional features to enhance the extrusion application. These include an intuitive graphical user interface to control temperature zones and motors, management of recipes and optimal processing values (exportable via USB), trends relative to temperatures and essential production values, excel formatted reports and printouts, pre-programmed auto start, video camera via Ethernet (netcam) for remote visual monitoring of machine functions, connection for tele-assistance via modem or via internet, PLC diagnostics, unlimited language management and a host of other features.
