use:
This unit is suitable for blowing polypropylene (PP) plastic film, which is widely used in the packaging of civilian and industrial products such as food, clothing, textiles, and daily necessities.
Features:
1.The die head can rotate around 360 degrees, which can enhance the strength and uniformity of the plastic film.
2.The screw and barrel are made of 380CRMOALA alloy steel, which is made of nitriding treatment and precision processing, with high hardness, strong corrosion resistance and durability.
3. The die head is plated with hard inscription, and its structure is a spiral mandrel type, the extruded molten material is uniform, and the blown film has a good finish; the air-cooling device has a labyrinth-type structure with uniform air output and is cooled by circulating water. So that the blown film achieves transparency.
4. The winding device adopts pressure friction winding or center winding, which is adjusted by a torque motor, and the winding is smooth and easy to change.
