The main reason for poor blown film forming of small blown film machine

The small blown film machine is compacted and precision machined. The specially designed screw has high output and good plasticization. It has the advantages of high production, stability, power saving, low noise, saving labor resources, less waste, bright and smooth film, and good hand feeling. And after many technical innovations and improvements, the accuracy and flatness of the product have been greatly improved, and the application difficulty of the operation process has been reduced.

    The blown film machine screw and barrel are made of alloy steel, which is nitrided and precision machined. It has strong corrosion resistance, acid and alkali resistance, high hardness and durability. The structure is a spiral mandrel type, the extruded molten material is uniform, the blown film has a good surface finish, and the coiling device adopts pressure and friction to control the winding or center winding, and the winding is smooth and convenient for changing the volume.

    In the blown film forming process, a variety of factors will lead to poor blown film formation, generally the following points: the film thickness is not enough, the film is more sticky, the film has wrinkles, the film is not tough enough, the strength is low, The film is vaporized and coked, the optical quality of the film is not good, the film has bubbles, the film has an impression, and the film has a pattern or a straight line.
