After the screw of the blown film machine wears out, uneven plasticization of the melt leads to large deviations in film thickness and the appearance of crystal points on the surface. Daokedao adopts nano WC particle reinforced cladding technology, with a surface coating hardness of HRC65 on the spiral edge. The wear resistance is three times higher than that of nitriding treatment, and the plasticization uniformity is improved by 20%. By precisely controlling the melting temperature, the straightness error of the screw is ≤ 0.01mm/m, and the gap between the screw and the barrel is maintained at 0.1-0.15mm. For different raw materials such as PE and PP, four sets of process parameters are preset, and the life of the strengthened screw of the Φ 65mm blown film machine is extended from 10 months to 32 months. After application, the thickness deviation of the film was reduced from ± 0.02mm to ± 0.008mm, and the number of crystal points was reduced by 90%, making it suitable for blown film production scenarios such as food packaging film and plastic film.
