Abstract:
A co-extrusion composite die for producing composite sheets and a composite sheet production equipment. A surface material and a bottom material are co-extruded by a composite extrusion die. The co-extrusion composite die is formed by assembling a first body (301), a second body (303) and a middle body (302), and the temperatures of the three bodies are differed from one another by means of an independent temperature adjustment system, thereby achieving the effect that the temperatures of a surface fluid extrusion channel (331), a bottom fluid extrusion channel (332) and a merging channel (333) in the same die are different from one another.
