· Screw and barrel are designed to adopt the special compounding function to melt at high speed and homogeneous, also get greater output.

· Spiral flow channel die is designed to stabilize melt flow. Optional rotating device is chosen and helpful to eliminate gauge band on the web.

· Air/ water rings are alum-alloyed special design for providing excellent and stable cooling. The combination of air and water cooling rings for water output and air blow stably working together, which results in excellent film transparency, film surface is evenly and glossy.

· Take-off unit allows adjustment to the proper height and provides effective film cooling.

· A variety of winders including manual, 2 bobbin type, 4 bobbin type, back to back winder with computerized tension control for high quality film. Computerized speed control system of take-off and winding units will provide precise winding quality, won' t cause tensile or broken of film.
