Each layer of flow channel is specially designed for each specific polymer.Comparing with co-extrusion through die and feed block,multilayer manifold die can get more uniform and accurate proportion of each layer of polymer.There are separate temperature control units in each layer of flow channel,with heat insulation device.
· Percentage of surface layer can reach as little as 5%
· Suitable for co-extrusion of different polymers with different melting points,the largest melting temperature difference is 80℃.There are separate temperature control units in each layer of flow channel,with heat insulation device.
· Can produce much more layers co-extrusion profile together with customized feed block.
· Can be equipped with width adjustment device(deckle system).
Multilayer coextrusion sheet die series
· Restrictor bar is optional,dealing with more kinds of polymers with different viscosities.
· Can be installed width adjustment device(deckle system),easily getting the products with different widths.
· Fast lip open system,replaceable die lip and pull&push fine-tuning bolts are available to choose for controlling die lip open gap,getting products with different thickness.
