Product Details

It is double screw plastic film extruding machine. The double color film blown machine used for blowing various low density polyethylene(LDPE) and high density polyethylene(HDPE) color striped plastic film, etc., which are widely used for packing food, fruit, garments textile, daily necessities and other civil and industrial products. The cylinder and the screw are made of high-quality alloy steel with optimum hardness and strong corrosion resistance after precision finishing and nitrogen treatment. 600 auxiliary machine can be freely adjusted within the limits of 600mm according to the technological requirements of different materials, and has been fitted with a plug-in plate mechanism for making vest bag.

The double-die color strip blown film unit produced by our factory is composed of two-sided three-knife screw barrel and one die. It adopts two kinds of master batch configuration and blows various color strip vest bags (shopping bags). It can achieve colorization without printing, and has the characteristics of bright colors, uniform lines, reasonable structure, advanced technology, smooth winding and high production capacity.

Characteristics:

1. The screw and barrel are made of nitriding treatment and precision machining. The hardness and tolerance is high; the corrosion resistance is strong, and the barrel is durable.

2. The die is plated with hard chrome, whose structure is spiral mandrel type; the extruded molten material is uniform so that the blown film has good surface finish; the air-cooling device structure is labyrinth type, and the air output is uniform.

3. The winding device adopts pressure friction winding or center winding, which is adjusted by torque motor, smooth in winding and convenient for changing rolls.

4. 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.
