Features:
1) The unit extruder, barrel, screw adopt high-quality steel,
nitride tight handling and precision
machining, with the best hardness and corrosion
resistance, a specially designed screw high
yield, good plastic.
2) The main motor adopts frequency control of motor speed to improve the speed regulating stability of main motor and save electricity by 30%.
3) The screw and material barrel adopt 38 chrome-molybdenum aluminum which has been nitrogen treated and the traction frame adopts lifting type.
4) No matter what size the film is, big or small, it can
achieve the best effect of cooling.

Use:
Both the cylinder and the screw of the extruder are made of high
quality alloy steel through nitration and precision finishing with
the best hardness and corrosion resistance. Scientifically
designed, this machine set has two heads for one extruder with such
advantages as increasing production capacity, saving energy, labour
and workshop area, etc...
This machine set is used for blowing Low-density
polyethylene(LDPE)and high-density polyethylene (HDPE)plastic film
to make various vest bags and flat-rim bags which have been widely
used for packing in the food industry, garment industry and textile
industry, etc...
