Nozzles Regulate Thickness
Adaptive Flow Resistors in the Spiral Mandrel Tool Compensate for Volume Flows
Wall thickness fluctuations often occur during the production of blown films. Spiral mandrel dies with adjustable nozzles can balance the volume flows and thus deliver more uniform film thicknesses. The Institute for Plastics Processing (IKV) has taken the first steps to develop such a system.
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
