ACCURATE, PRECISE EXTRUSION CONTROL TrueWeighTM Gravimetric Control System allows extrusion processors to put their equipment on “cruise control.” It tracks material being fed to the extruder and automatically adjusts screw rpm and the haul-off device to maintain a consistent product output regardless of changes in raw materials, ambient conditions or processing variables. The system offers functionality that suits both mono-layer and co-extrusion applications in film, sheet, extrusion coating, pipe, profile, tubing and wire & cable extrusion. TWC Controller AUTOMATES EXTRUSION CONTROL BY WEIGHT Varying process conditions, backpressure, material bulk density, and even operator skill sets can reduce extruder throughput and affect productivity and profitability. This easy-to-use extrusion control system gives processors complete visibility and control over throughput and finished product dimensions. TrueWeigh coordinates operation of up to twelve (12) extruders, governing not only total product throughput and dimensions, but also the relative weight of different layers. Processors realize increased yield through precise, consistent control over extruder output and weight per length to maintain consistent rate and product thickness. Product quality can be improved with precise layer-ratio control in co-extruded film or sheet, and through better dimensional stability in tubing, pipe and profile wall thickness. Tightens tolerances, saves material costs TrueWeigh allows processors to run products at minimum thicknesses (+/- 0.5% of set point). The extrusion control system synchronizes the extruder(s) and the haul-off device, optimizing stability of the production process and creating less start-up scrap by achieving production speeds quicker, and reducing or eliminating off-spec scrap. Easy-to-use, intuitive touch screen 5.7 inch LCD touch screen controller with full color graphics allows quick and easy set-up. User-friendly screens are configurable to match each specific extrusion process type. Simple menu driven touch screens use a Q&A approach to guide the operator through set-up. The operator can monitor the extrusion control set points, the haul-off control data, current and past alarm status and complete management of material inventory data. Quality maintained during transitions Advanced programming ramps extruder(s) and haul-off drives synchronously. This allows the system to make smooth transitions from one line output setting to a new target output while maintaining product quality.
