· 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).

· 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.
