5-9 layers co-extrusion, can choose various interlayer structure. Double-layer platform design of extrusion system, high-accuracy closed- loop control system of extrusion pressure. Available to install the weightlessness feeding system, and closed-loop control with extruder, to guarantee the extrusion capacity. High quality alloy steel automatic die head, make thin film's thickness more uniformity. Interlace helical flow channel design of casting roll ensure the less error of surface temperature. Infrared online automatic thickness gauge, can detect every layer`s thickness. Full-automatic double-station winding machine, to coil the film in gap or winding contact mode can be adjustable. Winding tension is closed-loop control, conical degree is automatic calculated, guaranteeing the constant of tension.
