Abstract
In a co-extrusion system, a primary extruder is connected to a primary flow director to direct the solid melt from the primary extruder to the co-extrusion assembly. A secondary extruder is connected to a secondary flow director to direct the melt from the secondary extruder to the co-extrusion assembly. A co-extrusion assembly produces simultaneous co-extruded melts without any significant pressure change in the melt. Dies shape the co-extruded melts to a desired shape.
