PVC Parallel Twin Screw Barrel

This Nanhaiya screw barrel set is specifically optimized for PVC processing, featuring high torque, strong feeding, and uniform plasticizing. The parallel twin screw design ensures excellent melt homogeneity while reducing shear-induced material degradation. Made from high-grade steel with a thick nickel-based and tungsten carbide alloy layer, the barrel offers long service life even under continuous high-speed operation.

Product Parameter (Specification)

Product Feature and Application

Nanhaiya PVC parallel twin screw barrels provide consistent melt quality, high output, and excellent wear resistance. They are widely used in PVC profiles, pipes, and foam board extrusion. The design accommodates high filler and recycled content without compromising quality or throughput.

Production Details

Each Nanhaiya parallel twin screw barrel undergoes advanced CNC machining and precision grinding. The surface is mirror-finished to minimize friction and improve plastic flow. The screw flight is hardened by nitriding or bimetallic alloy coating for long-term stability.
