Segment Screw Barrel

The segment screw barrel system allows different functional elements—such as conveying, mixing, and kneading sections—to be freely combined according to process requirements. Each segment is made of nitrided alloy steel, providing outstanding hardness, high torque strength, and wear resistance. The modular design allows rapid replacement of worn parts, minimizing downtime and reducing maintenance costs. Nanhaiya’s modular barrels are compatible with international brands like Coperion and JSW.

Product Parameter

Product Feature and Application

Nanhaiya segment screw barrel provides flexibility, durability, and high performance. The segmented design allows users to adjust screw configuration according to material formula or processing purpose, achieving optimized plasticizing, mixing, and dispersion. It is widely applied in engineering plastics, filler compounding, masterbatch, and additive extrusion.

Production Details

Each Nanhaiya segment screw barrel is processed by CNC and undergoes vacuum heat treatment. The inner liners can be replaced individually, improving cost efficiency. Alloy coatings are optionally applied on high-wear sections to further extend service life. Nanhaiya segmented system delivers stable operation, easy maintenance, and long-term reliability, helping customers achieve continuous high-performance extrusion production.
