Mainly Consisting of System

Mainly consisting of system is also included that “auto loader” “screen changer”.

Optional System Parts:

• IBC system

This system not only can rapidly cooling bubble, exhaust inner heat, water molecules and emissions of bubble,but also can supply new cooling air , lower the inner temperature of the bubble, increase the output and improve the mechanical properties of films.

• Take off Unit with Rotary System Unit

Haul-off Tower : Column adopts 140 mm*140 mm square tube, height 6 m, 2 floors platform, guardrail height 1.1 m;

Haul-off Speed : Max 60 m/min

Roller Length : 1,100 mm

Roller Material:Synthetic rubber

The film rotating device are moving relatively to the bubble at the speed of 0. 1 – 0. 3r / min for ± 360 °, so that the thickness deviation caused by die, the air ring and the tower frame is distributed at random, which ensures that the high-quality film are rolled at the winder.

• EPC System

Correct the film.
