The first step for automation of extrusion lines consist of a gravimetric.
Due to recording and control of the product weight maximum savings are achieved. The final product shows a considerably lower fluctuation range, so that waste and start-up scrap are reduced. Additional product weights can be reduced to a minimum via regulation. As the system records the real throughput in kg/h, fluctuations due to bulk density, material temperature or process engineering modifications of throughput can be compensated resp. corrected.
