The kneading block of the twin-screw extruder is responsible for material mixing and plasticization. Due to severe shear wear, its service life is only 3-5 months, and the cost of replacing a single set exceeds 50000 yuan. Daokedao adopts nano WC particle reinforced cladding technology, and the surface coating hardness of the kneaded block reaches HRC68, with wear resistance increased by 5 times compared to traditional nitriding treatment. For the special tooth profile of the kneading block, a five axis linkage melting system is adopted to accurately replicate the tooth profile, with a tooth top clearance error of ≤ 0.03mm. After repair, the mixing uniformity of the kneading block is improved by 25%, and the material dispersion compliance rate is increased from 85% to 99%. After the repair of a modified plastic factory's Φ 65mm twin-screw kneading block, the service life has been extended to 15-18 months, with a single repair cost of 12000 yuan and an annual cost savings of 80000 yuan for replacement. The device is equipped with 10 sets of kneading block process parameters of different specifications, reducing the time for changeover and debugging to 1 hour.
