The mixing function of the melt pump combined with the filtering function of the screen changer ensures uniform dispersion of color masterbatch, preventing color spots or streaks. For POE/HDPE calcium carbonate high-filler composite materials, the melt pump provides sufficient shear force to disperse fillers, while the screen changer intercepts undispersed large particles, enhancing the mechanical properties of the finished product.
The pressure-stabilizing function of the melt pump combined with the continuous filtering function of the screen changer ensures consistency in pressure, temperature, and viscosity of the melt at the die head. The screen changer reduces wear on the melt pump gears caused by impurities.
Actual case studies show that the combined use of both can extend the lifespan of melt pump gears by 40% and reduce the frequency of screen changer filter mesh replacement by 50%.
The combination of the melt pump and screen changer is an efficient solution for POE/HDPE pellet extrusion production, with core value in enhanced process stability, optimized product quality, extended equipment lifespan, and reduced production costs. When selecting equipment, consider material characteristics, production scale, and budget, and prioritize suppliers with proven application cases (such as Zhengzhou Batte) to ensure system compatibility and long-term operational reliability.
