The die head can choose 360 degrees of rotation, can enhance the strength and uniformity of the plastic film.
The screw and material cylinder are made of 38CRMOALA alloy steel, through nitriding treatment and precision processing, high hardness, strong corrosion resistance, durable.
Die head coated with hard chromium, its structure is spiral mandrel type, uniform molten material and good film finish; air cooling device is labyrinth structure with uniform air volume. The circulating water is used to achieve good transparency.
The winding device adopts pressure friction or central winding, adjusted by torque motor, smooth winding and easy roll changing.
