Dynisco Instruments, represented in Australia and New Zealand through Tasman Machinery , will highlight a number of new products at NPE 2009, in Chicago. Among the products to be showcased is the new OPT.TROL modular extrusion control system, which can be utilised across the full range of extrusion processes. OPT.TROL offers in one simple package, auto tuned temperature control, pressure control, speed control, trends, SPC/SQC functions and recipe storage.
OPT.TROL can either be retrofitted to increase productivity on existing lines utilizing old technology or installed on new lines. OPT.TROL can be configured with as few as 8 zones to a maximum of 40 zones of control. The temperature control was developed to allow single screw, twin screw, co-extrusion, or blown film applications to be run. Fully automatic adaptive tuning, (as well as conventional tuning) is provided. Automated heat start up is also a standard feature.
The operating station utilises touch screen technology, displaying process trends as well as on-board SPC functions. The use of pre-defined screens, and sequence control simplify set ups for users. Recipes, screen captures and logging functions can be stored and loaded from various memory devices.
